Exploring the Key Features of Pipe Conveyor for Efficient Material Handling
The pipe conveyor, an advanced form of belt conveyor, offers unique advantages that make it an excellent choice for various industries. In addition to the performance characteristics of conventional belt conveyors, the pipe conveyor stands out with its exceptional capabilities. This article will examine its key features and explain why it has become a preferred solution for material transportation.
Versatile Material Transport
The pipe conveyor systems is a highly versatile piece of machinery with a wide range of applications across numerous industries, including steel, construction, paper, grain, salt, and chemical. Due to its versatility in handling a range of materials, the pipe conveyor has become a crucial bulk material handling equipment in efficient material handling processes.
Sealed Material Transport
The pipe conveyor's distinctive enclosed tubular sealed belt structure effectively prevents material spillage, dust generation, and external environmental influences, enhancing operational efficiency and safety. The sealed design significantly reduces material losses during transportation and minimizes the impact on the surrounding environment, making it an ideal solution for conveying slag, ore, and other materials.
Flexible Route Layout
The tubular conveyor's flexible route layout allows for convenient arrangement along curved paths, enhancing operational flexibility. The tubular shape of the belt provides excellent maneuverability, enabling it to negotiate curves with ease. The use of nylon fabric belts allows for a radius of curvature of up to 300 times the pipe diameter, enabling seamless routing through complex spatial curves.
Steep Angle Conveying
The tubular shape of the belt increases the friction coefficient between the material and the belt, allowing for efficient transportation at steep angles. The pipe conveyor system is capable of achieving inclinations of up to 30°, and for materials with poor flowability, inclinations of even higher levels are possible. This feature is especially advantageous for applications that require vertical material transport, as it reduces conveying distances, saves space, and lowers equipment costs.
Simultaneous Bi-directional Material Transport
The pipe conveyor offers a unique solution for simultaneous bi-directional material transport, utilising the upper and lower branches of the belt to provide a highly efficient and cost-effective solution for your material handling needs. The circular tube shape of both the loaded (upper) and empty load (lower) branches allows for the smooth transport of materials in opposite directions. This capability is invaluable for optimizing material flow and enhancing operational efficiency.
The pipe belt conveyor offers a number of significant advantages over traditional belt conveyors. The pipe belt conveyor is an ideal solution for industries seeking efficient and reliable material handling systems. Its ability to handle various materials, sealed transportation, flexible routing, steep-angle conveying, and simultaneous bi-directional material transport make it a versatile and reliable choice for a range of applications. By leveraging the unique features of the pipe conveyor, businesses can improve productivity, reduce material loss, minimize environmental impact, and optimize their operational processes.
Apron feeder is a heavy-duty conveyor designed to feed large lumps of ore and aggregate to downstream equipment. It has strong structure, smooth operation, uniform feeding (usually adopts frequency control system so as to adjust the operating speed, control the feeding volume and reduce the phenomenon of blockage), and it is the commonly used equipment in heavy load feeding and conveying system.
CAFU Machinery's apron feeder works as follows:
Our apron feeder is mainly divided into frame, crawler chain assembly (below), support rollers (sealed for life and self-lubricating), transmission system (including electric or hydraulic drive) and other components.
The grooved head sprocket is driven by an electric motor and reducer to move the crawler chain, which engages with the sprocket to pull the crawler chain track assembly with the material forward at a certain speed. The load carrying mechanism (support rollers) is rotated by the friction of the crawler chain track and carries the weight of the material and the running part. The frame, on the other hand, carries the entire weight of the machine and transfers it through the frame to the base of the machine.
The material is fed into the feeder from a hopper (or pit) located above the rear section of the apron feeder and moves forward through the crawler track assembly until it is discharged at the head.
For example, our CF1052 Apron Feeder is designed as a light-duty machine with a 20m3 feed hopper, which can transport limestone, ore and other materials with a particle size of not more than 600mm and a bulk density of 1.6t/m³ in use. It consists of a frame, crawler track assembly, support rollers, transmission system and other components.
The apron feeder requires minimal maintenance due to its tracked design. All components are 'sealed for life' and 'self-lubricating', requiring virtually no maintenance. This ensures that our customers enjoy long-term reliability and minimal downtime.
The 20m3 hopper liner is robustly constructed from wear resistant steel.
In practice, the apron feeder has several advantages. It provides better feed control for downstream equipment and prevents clogging; it absorbs the impact of material loaded directly onto the feeder, especially in shallow layers; and it is flexible in its application, recovering dry or wet material of any size at a uniform rate. In addition, its crawler chain track uses a track and roller design similar to that used in bulldozers and excavators, with polyurethane seals in the rollers to prevent the ingress of abrasive materials, making the slat feeder easy to operate and maintain and extending its service life.
In addition, the apron feeder can be installed not only horizontally, but also on an incline (usually not more than 20 degrees), which saves overall space and offers a number of other benefits and features. However, there are certain requirements and specifications (as outlined in the Apron Feeder Installation Guide) that must be followed when installing and using the apron feeder to ensure proper operation and performance.
As an excellent representative of bulk material handling equipment, CAFU Machinery has always made it an important goal to supply the highest quality apron feeder handling equipment to the mining industry, we continue to innovate and improve our products through user feedback, which has made our products trusted for more than 10 years. Please do not hesitate to contact us to order the most professional equipment for your aggregate handling needs.
The pneumatic conveying system for cement grinding is a technologically integrated system that uses air flow as a conveying force to convey powdered materials such as cement powder in pipelines. It mainly consists of conveying pump, conveying pipeline, gas source and purification equipment, gas-solid separator (such as dust collector), fan and other components.
The working principle of the system is to push the materials to be conveyed along the airflow direction in the airtight conveying pipe by the airflow generated by air compressor or Roots blower.
The pneumatic conveying system for cement grinding has the following characteristics.
• High flexibility: the piping arrangement is flexible and not affected by existing buildings or terrain.
• Good environmental protection: the equipment is completely enclosed, less dust flying, can meet environmental protection requirements.
• Easy to maintain: the system is highly integrated and can be controlled automatically.
• High conveying efficiency: capacity from 1 tonne to 300 t/h.
• Convenient operation: materials can be conveyed centrally from dispersed points to one place, or dispersed from one place to many other places, which is convenient for long-distance operation.
In a cement plant, the design of a pneumatic conveying system for the cement grinding and unloading area requires a number of factors to be considered.
In general, this pneumatic conveying system has a large conveying capacity (about 150-300 tonnes/hour) and a long conveying distance. The system continuously feeds the material from the air chute to the conveying pump, how to avoid blockage at the back end of the system and ensure the smoothness of the front end of the system will be the key to the design of the pneumatic conveying system for the cement grinding and unloading area.
Firstly, the conveying distance and conveying capacity should be considered. If the conveying distance is long and the conveying volume is large, a dense phase conveying system may be required to ensure that the material can be transported to the destination in a stable and efficient manner. In this case, if the conveying is continuous (uninterrupted conveying), then the double conveying pump system needs to be considered.
Secondly, the design of the piping system may require specially designed conveying pipes and equipment to prevent clogging and wear.
Further, system reliability and maintenance costs need to be a key concern. Advanced pneumatic conveying systems offer a higher degree of automation and lower maintenance requirements, but the initial investment may be higher. Relatively simple systems, on the other hand, are less costly but may require more manual maintenance and troubleshooting in long-term operation.
Also, energy consumption is an important factor. The energy consumption of different types of pneumatic conveying systems varies greatly, and detailed calculations and comparisons are needed to select a solution that consumes less energy while meeting the conveying requirements. Under the same conditions, dilute-phase conveying pipes need to be larger, and energy consumption is relatively high, so it is generally used in systems with smaller conveying capacity (less than 120 tonnes per hour).
Finally, the overall layout of the plant and the compatibility of existing equipment need to be considered. Ensure that the new pneumatic conveying system can be seamlessly integrated with other production processes, without affecting the smooth operation of the entire production process.
In conclusion, when designing a pneumatic conveying solution for the cement grinding and unloading area, it is necessary to weigh all the above factors and design the best solution according to the specific production needs and conditions.
CAFU Machinery is a specialist supplier of pneumatic conveying system. Our products are widely used in cement production, thermal power generation and other fields. If you have any requirements in this products, please do not hesitate to contact us.
Select The Appropriate Material for Customized Blow Bars for Impact Crusher
The blow bar is a crucial consumable item for impact crushers, typically comprising a chrome-based mixture. The primary function of the blow bar is to repeatedly rotate at high speed to impact the aggregate, thereby breaking down materials such as asphalt, concrete, limestone, and others to achieve the desired particle size.
Typically, users select the appropriate blow bar material based on the specific functions of their impact crusher.
CAFU's impact crusher blow bar is available in a wide range of materials to suit your specific requirements, including manganese, low chrome, medium chrome, high chrome, martensitic and composite ceramic.
High Manganese Steel
Given the characteristics of manganese steel with an austenitic structure, high manganese steel is typically selected for less abrasive aggregates (e.g., limestone) and larger feed sizes in impact crusher applications.
Chromium Steels
The chrome steel blow bars for impact crusher is a crucial component, also known as an impact crusher plate hammer or hammer head. Typically, these bars are crafted from wear-resistant materials, such as high-chrome alloys, which offer high hardness and wear resistance, making them ideal for use in crushing ores, rocks, and other materials.
The key features and benefits of the chrome steel impact crusher striking bar include:
• The product is highly resistant to abrasion, made from high chrome alloy and other wear-resistant materials, which enable it to withstand the impact and abrasion of materials during the crushing process, thus prolonging its service life.
• This product offers high crushing efficiency thanks to its reasonable design, which effectively crushes materials into the required particle size, thereby improving crushing efficiency.
• It is highly adaptable and suitable for use with a wide range of materials, regardless of hardness or particle size.
When selecting a chrome steel impact crusher blow bar, it is essential to consider the following factors:
• Material characteristics, including hardness, particle size, and humidity, must be considered to ensure the percussion bar can meet the crushing requirements of the material.
• Crusher type: It should be noted that different type of impact crushers may require different sizes and shapes of blow bars.
Due to the low toughness of chrome steel, blow bars must undergo a heat treatment process and the parameters such as temperature range and annealing time must be strictly controlled in order to prevent the material from becoming brittle.
Martensitic Steels
The primary alloying elements of martensitic steels are iron, chrome, and carbon. While martensitic steels offer high strength and hardness, they have relatively poor plasticity and toughness. Consequently, during the heat treatment process, carbon is removed from the martensite in order to enhance the material's strength and wear resistance.
In terms of hardness and toughness requirements, martensitic steels occupy an intermediate position between manganese and chrome steels. They offer good wear resistance and good resistance to impact stresses. In case of weak impact capacity, martensitic steel should be preferred as it cannot harden the surface of manganese steel.
Alloy Steel & High Chromium Ceramic Composites
Alloy steel and high-chromium ceramic composites offer a unique combination of high wear resistance and extremely hard ceramics. The liquid metal is drawn into the porous ceramic network by the ceramic preform, which allows the composite to be formed.
This composite makes the blow bar particularly wear-resistant and also provides excellent impact resistance. The ceramic microhardness of the infiltrated composite is ≧1800HV, which significantly extends the service life by 80-100%.
As previously noted, the enhancement of steel wear resistance (hardness) is typically accompanied by a reduction in toughness (impact resistance). Consequently, when selecting blow bars for impact crusher, it is essential to consider the specific application environment holistically to identify the optimal alloy material for achieving the best overall performance.
Crusher jaw plates are mainly used as liners for primary and secondary crushers, which are widely used in mining industry, building material production, aggregate processing and other industries.
As a kind of commonly used crusher spare parts, crusher jaw plates mainly consist of two jaw plates combined.
One is the fixed jaw (stationary jaw), which is vertically fixed on the front wall of the frame.
The other is the movable jaw (swing jaw), its position is inclined, it and the fixed jaw to form a relative angle of the crushing chamber.
Due to the periodic reciprocating motion of the movable jaw plate and the fixed jaw plate, the aggregate is crushed by strong extrusion.
As a result, the movable and fixed jaws are the most frequently replaced wear parts of a jaw crusher, and CAFU can manufacture jaws in a variety of tooth shapes and materials to suit your operating conditions. Our crusher jaw plates are made of cast high manganese steel with 13% and 18% manganese and 2% chromium.
In addition, we can customize special crusher jaw plates to increase performance by using even higher manganese content (21% and 23%) and 3% chromium.

The wear resistance of crusher liners can usually be tested by the following methods:
1. Hardness test: The hardness of the liner is measured by a hardness tester, and the hardness reflects its wear resistance to some extent. Common hardness testing methods include Brinell, Rockwell and Vickers hardness.
2. Wear test: A simulated wear test can be performed in the laboratory, such as using a wear tester to rub a liner sample against an abrasive material under certain conditions and then measuring the amount of wear.
3. Chemical composition analysis: The chemical composition of the liner is examined and the content and ratio of certain elements, especially manganese, will affect its wear resistance.
4. Microstructure observation: The microstructure of the liner is observed by metallurgical microscope and other equipment, such as grain size, phase distribution, etc. Good microstructure helps to improve wear resistance.
5. Actual use test: Install the liner in the crusher for actual operation, and check its wear level after a certain period of time.
There is usually a positive correlation between the wear resistance of a liner and its hardness.
In general, the higher the hardness, the more wear resistant the liner will tend to be. Higher hardness means that the surface of the liner is less susceptible to scratches, dents, and deformation from friction and impact with the material.
However, hardness is not the only factor that determines wear resistance. The wear resistance of the liner is also affected by its chemical composition, microstructure, toughness, and other factors.
For example, simply striving for excessive hardness can reduce the toughness of the liner, making it susceptible to fracture under high impact. Good microstructure, such as fine and uniform grain structure, also helps to improve wear resistance.
In addition, the working conditions of the liner in practice, such as the type of material, impact strength, temperature, etc., will also affect the wear resistance.
Therefore, when considering the wear resistance of crusher liners, it is necessary not only to use hardness as an indicator, but also to consider a variety of factors in a comprehensive manner.
Several methods can be considered to optimize the hardness and toughness of crusher liners:
1. Material selection and alloying:
• Select suitable base materials, such as high-quality manganese steel, and add appropriate amounts of alloying elements, such as chromium, molybdenum, and nickel, to improve their performance.
• Precisely control the content and proportion of alloying elements to achieve a balance between hardness and toughness.
2. Heat treatment process:
• Adopting suitable heat treatment process can improve the hardness of the liner and strengthen the toughness of the liner.
• Optimize the heat treatment temperature, time and cooling speed and other parameters to achieve the ideal organization and performance.
3. Micro-organization control:
• By controlling the casting process parameters, such as casting temperature, cooling rate, etc., to obtain a fine and uniform grain structure, thus improving hardness and toughness.
• Adopt advanced processing technology, such as shot blasting, etc., to improve the microstructure.
4. Optimized design:
• Optimize the design of the shape and structure of the liner to reduce stress concentration and improve the overall mechanical properties.
5. Quality control:
• Strictly control the quality of raw materials in the production process to ensure uniform composition.
• Strengthen quality inspection in the production process, timely detection and treatment of defects.
Selecting the appropriate material and profile for customized mill liners is a crucial aspect of the process.
Mill liners serve to mitigate the impact and abrasion of the grinding media, safeguard the mill shell from wear and impact, and extend the lifespan of the mill. During the grinding process, hard ores, as well as steel balls and rods, are subjected to repeated impact on the shell. Without the protection of a well-designed mill liner system, the shell will inevitably suffer damage.
The mill liner system comprises the following components:
Liner Body: The liner body is typically cast from wear-resistant materials, including high manganese steel, high chromium cast iron, alloy steel, and others. Additionally, liners are available in a combination of rubber and steel backing plates, offering versatility for use with different materials.
Fixing Device: The fixing device is typically secured with 10.9 grade high-strength special bolts. The bolts are available in three different head shapes: round, square and oval. The purpose of the mounting is to secure the liner firmly to the mill shell, thereby preventing loosening and potential detachment during mill operation.
Sealing Parts: It is essential to ensure that the liner and the mill shell are properly sealed to prevent material leakage. The fixing device (bolt) of the liner should be fitted with a 10mm thick rubber gasket to effectively isolate the gap between the bolt holes and the outside.
A mill liner with a reasonable contour shape can optimize the material flow and grinding effect in the mill, reduce the energy consumption of the mill and improve the production efficiency.
The design of mill liners varies considerably from one application to another and cannot be generalized. The range of mill liner types includes flat liners, platen liners, cambered liners, spiral cambered classification liners, wave liners, step liners and so on. This variety allows us to provide the right solution for each application and process section within the mill.
In most cases, mill liners can be further classified according to their specific roles, with the categories typically including shell liners, diaphragm liners, and lifter liners.
When customizing mill liners, it is essential to make careful trade-offs (in most cases, the original design can be retained) with full consideration of factors such as mill dimensions, operating conditions and material properties. This allows for the optimization of liner selection, if necessary, in order to achieve highly efficient grinding, a prolonged equipment service life and increased overall productivity.
The selection of mill liners for different mills depends on a number of factors.
SAG Mill
SAG (semi-automatic grinding) mill liners are typically made of cast alloys. In some cases, steel-backed rubber liners may be used, depending on the size and nature of the material being processed. Due to the necessity of withstanding the considerable impact of the big material, the alloy steel liner must be not only wear-resistant, but also highly impact-resistant. An appropriate ratio of casting material and a suitable heat treatment process can significantly improve the impact resistance of mill liners.
Ball Mill
Ball mill are a common piece of equipment in the mineral processing industry, particularly for processing cement raw materials. Their primary function is to grind a range of materials into a fine powder. Ball mill liners are typically manufactured from high manganese steel, high chromium cast iron, chromium-manganese alloy, and a rubber-steel backing plate combination. Following heat treatment, these liners demonstrate extremely high wear and impact resistance. The typical service life is 6,000 to 10,000 hours.
Rod Mill
A rod mill is a key piece of equipment used for grinding ores. The use of steel rods as grinding media offers several advantages over ball mills. The line contact between the rods is more favourable to coarse grinding operations, effectively avoiding the issue of over-crushing. Rod mill liners are typically manufactured from high manganese steel or high carbon alloy steel, which can significantly extend the service life of the liners and minimize machine downtime through the use of optimal contour design and configuration.

Each type of crusher liners is designed and manufactured to meet the specific working needs and crushing process requirements of different types of crushers.
When selecting the most suitable crusher liners for your needs, it is advisable to consider the following factors:
1. Material Characteristics: It is important to understand the hardness, humidity, particle size, and corrosiveness of the material to be crushed. For high hardness materials, it is necessary to choose a stronger, more wear-resistant liner material.
2. Type of Crusher: Different types of crushers (such as jaw crushers, cone crushers, impact crushers, etc.) have different working principles and crushing methods, which in turn require different liner shapes, structures, and sizes.
3. Liner Material: In addition to manganese steel, other materials are available, including high-chrome cast iron liners, alloy steel liners, and so on. The choice of material should be made according to budgetary constraints and the actual needs of the application. For example, high-chrome cast iron offers high wear resistance but is relatively expensive.
4. Quality and Workmanship: High-quality liners are typically produced through a meticulous casting process, free from defects such as porosity, slag entrapment, and surface irregularities.
When selecting the optimal crusher liners, it is essential to consider a multitude of variables. If you are seeking a dependable supplier of manganese steel crusher wear part, we invite you to contact CAFU.
Crusher liners is an important part of the crusher. It is usually installed in the crushing chamber of the crusher, directly in contact with the crushed material, commonly used in cone crusher, jaw crusher, impact crusher, gyratory crusher. its main functions include:
1. Protect the crusher body: Reduce the wear and impact of materials on the crusher body and prolong the service life of the crusher.
2. Improve crushing effect: Through reasonable liner shape and design, it can optimize the crushing process of materials and improve the crushing efficiency and product quality.
3. Enhance the crushing force: Change the trajectory and force state of the material to enhance the effect of crushing force.
The materials of crusher liners are mainly as follows, and the performance characteristics of each material are as follows:
1. High-manganese steel: Manganese crusher liners have good toughness and work-hardening properties. When subjected to heavy impact and extrusion, the surface will harden rapidly, thus improving wear resistance. However, under low impact load or low stress wear conditions, the work hardening effect is not obvious, and the wear resistance may not be as good as some other materials.
2. Alloy steel: Alloy steel crusher liners higher hardness, high strength, wear resistance is better. Through the reasonable proportion of alloying elements, you can get different performance, adapt to a variety of working conditions.
3. Wear-resistant cast iron: With high hardness and certain toughness, relatively low cost. However, in the extremely harsh wear environment, its wear resistance may be slightly inferior.
4. Ceramic composite materials: Ceramic composite series, including high manganese steel ceramic composite materials, alloy steel ceramic composite materials, high chromium ceramic composite materials. Extremely high hardness, excellent wear resistance and good chemical corrosion resistance. However, ceramic composite materials are more brittle and may be prone to fracture under strong impact.
The crusher wear part selects different materials with different wear resistance and strength characteristics to adapt to different crushing conditions and material characteristics. Its shape and structure are also various, such as corrugated, serrated, etc., to meet different crushing needs.
In practice, the selection of crusher wear liners requires comprehensive consideration of the crusher working conditions, the type of material to be crushed, the cost and other factors to achieve the best results and economic benefits.
Wear plate is a kind of plate with high abrasion resistance, usually made of special alloy material, which can withstand high-intensity abrasion and impact. In the industrial field, wear plate is widely used in mining, metallurgy, cement, coal and other industries in equipment such as crusher, conveyor, hopper and so on, in order to protect the body structure of the equipment and extend the service life of the equipment.
Wear plate screen, on the other hand, is a kind of screen made of wear plate with higher wear resistance and strength, which can be used for a long time in harsh working environment.
