(Summary description)The choice of pneumatic conveying system, how to choose a suitable pneumatic conveying system according to the type of material? As a highly automated material conveying system, there are many types of pneumatic conveying systems, and the conveying methods of materials in closed conveying pipelines are also different. According to different material characteristics, the appropriate type of pneumatic conveying system should be selected to achieve ideal conveying. The effect can meet the actual needs and process needs. Next, we will tell you how to choose the right pneumatic conveying system according to the type of material. 1. When transporting flammable and explosive materials such as chemicals, metal powder, plastic, coal powder, etc., safety measures such as explosion-proof valves and automatic fire extinguishing devices must be installed. 2. Sticky substances will stick and clog funnels and pipes. Therefore, the rotary feeder should preferably choose the vane rotary feeder. 3. If the fine powder content of less than 50 microns in the wet material is less than 10%, most of the fine powder can be conveyed by the traditional pneumatic conveying system. If the moisture content of the wet material is high, the wet powder will stick to the inner wall of the elbow, causing the pipe to be blocked, then the feeder should choose a blowing feeder. If the material is not too wet, the air can be heated to reduce bonding problems. 4. The static electricity of the material will produce adhesion, which will affect the fluidity of the material, and the air can be properly humidified. Dense phase conveying requires less gas and lowers humidification cost.   5. In the process of pneumatic conveying, most of the material crushing occurs at the bend of the pipeline. Therefore, in the design of the pneumatic conveying system, the number of pipe bends should be minimized to prevent material breakage. 6. Use dry air to prevent problems with hygroscopic materials. The material can be dried in advance by freezing or desiccant. Sometimes the moisture content of the material is not large, and the material can be conveyed by dense phase pneumatic conveying. 7. When the top discharge bin pump is not suitable for conveying granular materials, avoid using the offset rotary feeder. 8. During the conveying process, micron and sub-micron fine powder will be attached to the inner wall of the pipeline, thereby reducing the cross-sectional area of the pipeline and reducing the pneumatic conveying capacity. This problem can be solved by choosing flexible pipes with vibration function. The choice of pneumatic conveying system, how to choose a suitable pneumatic conveying system according to the type of material? When choosing a pneumatic conveying system, the viscosity and moisture content of the material should be detected. When transporting flammable and explosive materials such as plastics, chemicals, metal powder, coal powder, etc., safety measures such as explosion-proof valves and automatic fire extinguishing devices should be installed to ensure the safety of material transportation.
