Application It is mainly used for the transportation of cement, fly ash, calcium carbonate, titanium white powder, polyvinyl chloride powder, mineral powder, wood powder, etc. It has the advantages of environmental protection, long-distance transportation, not influenced by weather, convenient installation and high reliability. Principle This system uses fluidization technology and air pressure difference principle to achieve the purpose of powder transportation. According to the process technological requirements, the upper jet pump is selected, which is characterized in that it is suitable for powder conveying with large specific gravity and high moisture content. The bin pump uses the SIEMENS PLC to combine the man-machine interface control way, realized the intellectualized control.
