Coal mill dynamic powder separator
The coal mill dynamic powder separator is mainly used as a grading device in a coal mill coal preparation (pulverizing) system.
The material enters the powder separator from the air inlet pipe 11 with the airflow, reaches the upper part of the casing through the gap between the inner and outer cones, changes the direction through the guide vanes, forms a rotating airflow and enters the rotor. Under the combined action of the rotating airflow and the rotor rotation , Sort the materials. Qualified materials (fine powder) enter the rotor with the airflow, and are discharged through the air outlet. The finished materials are collected by the next level of dust collection equipment; unqualified materials (coarse powder) are collected by the inner cone of the powder separator and returned through the material. The slipper is sent back to the mill to circulate again.
