After completing the preparations, the next step is to conduct a no-load test run. This test is crucial to ensure that the feeder operates smoothly without any issues before being put into actual use.
1. Duration of Test Run
- The no-load test run should last for one hour. During this time, the equipment should operate normally without any abnormal noises, and there should be no signs of jamming or knocking in the moving parts.
- A one-hour test run provides sufficient time to observe the behavior of the feeder under no-load conditions. It allows us to detect any potential issues early on and make necessary adjustments before proceeding to the load test.
2. Inspection After Test Run
- Once the no-load test run is complete, stop the equipment and inspect all the connecting parts for any signs of loosening. Check the temperature rise of all bearing areas, the reducer, and the motor. Normal operation should result in a moderate temperature rise within the specified limits.
- Inspecting the connecting parts and monitoring the temperature rise helps ensure the integrity and reliability of the equipment. Any loosening of connections or excessive temperature rise may indicate potential problems that need to be addressed before proceeding to the load test.
Step 3: Load Test Run
If the no-load test run is successful, the next step is to conduct a load test run. This test simulates the actual operating conditions and helps determine the feeder's performance under load.
1. Preparation for Load Test Run
- Start by filling the hopper with gravel and powdered materials until there is at least a 500 mm thick protective layer of material on the load chain plate during operation. This protective layer helps prevent damage to the chain plate and ensures smooth material transfer.
- The choice of materials for the protective layer should be similar to the actual materials that will be handled by the feeder. This helps ensure that the test results are representative of the real-world operating conditions.
2. Gradual Increase in Material Flow
- Once the protective layer is in place, start adding the normal materials to be handled by the feeder. The material flow should be gradually increased to the rated capacity. This allows the equipment to adjust gradually to the load and helps detect any potential issues at different load levels.
- Monitoring the material flow and observing the behavior of the feeder during the gradual increase in load helps ensure that it operates smoothly and efficiently. Any signs of instability or excessive stress on the equipment should be addressed immediately.
3. Duration of Load Test Run
- The load test run should last for at least two hours. During this time, observe the feeder's performance closely. Check for any signs of abnormal noises, vibrations, or excessive wear. Monitor the temperature rise of the bearings, reducer, and motor to ensure they remain within the acceptable limits.
- A two-hour load test run provides sufficient time to assess the feeder's performance under continuous load. It allows us to detect any potential issues that may arise during prolonged operation and make necessary adjustments or repairs.

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.

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.
