Structures of attitor/attritor :

The main machine is composed of a frame, a stepless speed reducer, an automatic feeder and a crushing chamber. The crushing chamber is equipped with a classification device, a bushing, a crushing knife and other main working parts. The grading shaft hole is sleeved in the crushing main shaft, and the bearing is sealed as Labyrinth.


Working principle of ultrafine grinder/superfine pulverizer

The material is pushed into the crushing chamber by the automatic feeder. Due to the negative pressure, the material entering the crushing chamber is impacted and sheared at a high speed by the crushing knife. At the same time, it is crushed by the high-frequency vibration generated by the eddy current. The negative pressure enters the classifying wheel, because the rotating powder A of the classifying wheel is simultaneously subjected to the centrifugal force F of the aerodynamic force E.
