Impact crusher are mainly three kinds of crushing stone

Author:admin Hits:

The impact crusher member is a high-speed rotation of the rotor, with the hammer plate gob in the range of rotor rotation (i.e., the hammering area) fed into the machine by the impact of the hammer plate, the material is fed into the hammer zone by the guide plate, material block after the impact of the board hammer abandoned high speed crashed into the back plate, once again under attack, and then from the rebound counterattack plate to plate hammer, continue to repeat the process. In commuting between the material strike against each role. As the material by plate hammer blow, with the impact of the counter plate and the materials between the collision. Materials continue cracks, loose and crushed. When the material particle size is smaller than the gap between the counter plate and plate hammer is unloaded.

According to the principle of the introduction of the above work, it was found that the crushing effect of the impact crusher has the following three points:

(1) Free broken. Material into the crushing cavity immediately subject to the impact of the board hammer. Material between the impact and friction between the plate hammer and materials, supplies and materials, material crushing due to these effects.

(2) The rebounded broken. The broken material is not actually unlimited dispersed, but concentrated in the body due to the impact of high-speed board hammer, so that the materials are high movement speed, and then hit the counter plate perish material thereby further broken. Such a crushing effect called rebound effect.

(3) Milling effect. Has not been broken by the crushing effect of the above two is greater than the the irresolute inlet size of materials, the material at high-speed rotation of the plate hammer milling and crushing.
