The Rat case type crusher is composed of a base, side cover, stator, rotor, cutter bar, main shaft and bearing seat and a belt pulley. The whole machine is composed of feed hopper, main drive motor, crusher, frame and so on. Suitable for cassava, fruit, coal and so on.
 
When working, the motor drives the main shaft to rotate by a pair of belt wheels, The materials which are transported up and down from the previous process are free to fall into the feed hopper, and the material is pushed forward along the axial direction. After the coarse crushing, the material immediately into the fine crushing area, the rotor with high speed rotation of material, the knife on the stator will be further broken material (knife row can be used on both sides), at this point, the general size of the material is about 4-8mm, (according to the knife row of the tooth pitch, stator slot width and speed may be adjusted), then the material drop from the waist of the stator into the next process to the discharge port.
The utility model has the advantages of strong adaptability, two driving wheels are respectively driven by the two motors to rotate at different speeds when working. Raw material enter the machine from the feed inlet, enter the wheel center area through the adjustment plate, in the falling process, by the impact of the rotating rod repeatedly hammer, and the impact and friction between the raw materials, the crushed fine material falls from the discharge port.
