Next, the material enters into the special explosion-proof pulsed dust collector of the vertical mill for collecting finished product coal powder after being classified by the classifier. Last, the collected finished product coal fines are conveyed by silo pump pneumatic conveying system to the storage silo or conveyed to lime shaft kiln as fuel when necessary.

Meanwhile, in order to meet the requirements of customers for safety and environmental protection, the system is equipped with pulsed dust collector to guarantee the effect of dust removing, and carbon dioxide fire extinguisher, nitrogen gas explosion protection system and explosion valve. What’s more, there is also equipped with oxygen analyzer, gas detection instruments, various sensors and other automatic control accessories, which can timely and effectively prevent from the safety accidents and guarantee the continuous running time of the equipment to maximum.
