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.
