PNEUMATIC CONVEYING AND SORTING SYSTEM OF MULTIPURPOSE PULVERIZED COAL ASH PROJECT

The ash collecting unit improved by providing with dry conveying and sorting technology in the multipurpose pulverized coal ash project is briefly explained. The system has a remote operation function and a real-time supervisory system. Its installation does not require much space. Its running is smooth and its operation is simple. Now a reasonable sorting, a continual conveying and a recovery of the pulverized coal ash are all achieved. There is no any more secondary pollution. The wear of the charge and discharge valves has been solved. It is concluded that the system is worthy to be promoted for widespread application.
