Working Principle: The raw material enters the crushing chamber via a frequency-controlled screw feeder, where it is subjected to intense impact from the impact hammer, as well as impact, friction, and shearing in the gap between the impact hammer and the liner. The crushed material rises with the airflow to the classification wheel for grading, where micropowders meeting the fineness requirements are discharged. Features: 1. This machine integrates mechanical crushing and airflow classification into one unit, making it a new type of combined equipment with a compact structure. 2. This machine is equipped with a split-type unit.
