grinding and classification system for coal fly ash

Detailed Description:

I. Operational Mechanism

The feed mechanism initiates the transport of materials into the primary crushing compartment of the main apparatus. Inside this chamber, materials undergo extensive fragmentation via a synergy of impacts, collisions, frictions, shearing actions, and compressions with swiftly rotating elements and particle interactions. Subsequently, a grading wheel segregates the pulverized material into coarse and fine powders. The coarser fractions are recirculated back into the crushing chamber for intensified grinding, whereas the refined gas is expelled efficiently by the induced draft fan.
