( 1 ) rebound broken. The material is not actually broken unlimited dispersed , but are concentrated in the box-shaped frame body inside . Hammer against the action of high-speed rotation of the rotor , the material to obtain a high velocity, and the impact on the frame body , the frame body with the same size and opposite force to the material , the material is further broken, this crushing action called "rebound broken ."
( 2 ) Freedom in the crushing cavity broken. Ore into the crushing chamber , immediately hit the hammer on the high-speed rotation of the rotor impact , as the child playing with a lot of racket ball fragmented glass , hand tempo play, on the other hand between the glass balls hit each other . Meanwhile beat with glass balls and rubbing action between the ball and the ball is so crushing cavity material by crushing effect of external forces .
( 3 ) milling broken. That is not broken above two crushing effect is greater than the size of the port of discharge material , and broken by high-speed rotation of the hammer mill at the mouth of the discharge .
Learn from Impact Crusher crushing theory is the basis for technical achievements , " air strikes " established
Back ( also known as impact ) crusher works: mainly through the impact of high-speed rotary hammer material blocks along the weak part of it ( bedding , joints , etc. ) selectively broken. After the material has been hugely impact kinetic energy through the back plate and material impact inter further broken. The above process is repeated until a final qualifying products.
