Description

In the inertial cone crusher, the material block is subjected to the preset crushing force under the condition of strong inertial vibration, which can ensure the density of the material layer, make the particles bear the pressure in all directions, and realize the breakage in the layer.

 

Breaking force, directly related to the effect of crushing material blocks. The crushing force is too small, did not reach the material between the strength of the grain, the material is not broken. If the crushing force is too large, not only more than the material grain contact strength limit, but also make the object the grain itself is destroyed, this is not only a waste of energy and cause crushing harmful. Therefore, for each kind of material will be pre selected a suitable breaking force value, the material block only by grain boundary rupture without causing crystal damage, realize selective crushing.

 

The material is subjected to strong vibration in the crushing chamber, which can change the direction of the material blocks to each other, thus causing alternating shear and bending stress in the layer. At the same time, the powder that binds between the material blocks will be removed. These powders not only weaken the interaction between the material blocks, but also crush themselves, resulting in over-crushing. However, in the inertial crusher, because the material layer is strongly vibrated, the powder can be removed, thus improving the crushing effect between the materials. In the inertial crusher, because there is no rigid connection between the moving cone and the motor, the amplitude of the moving cone is not limited by the transmission system, and its size depends on the material layer.When the crusher starts, the crusher has small swing frequency, small crushing force and small amplitude, so the starting moment is also small, and the machine will not be damaged by starting with load. So the inertial crusher has the advantage of starting and stopping with load.
