Impact crusher model predicts better results

The working principle of the cone crusher is to apply the extrusion force to the material, so that the material is broken at the same time by the bending force and the shear force between the two cone surfaces, and the material can be unloaded after crushing. Its large production capacity and low power consumption. When the material is broken, due to the crushing force, a friction force is generated on the surface of the moving cone, and the direction is opposite to that of the moving cone. Because the upper and lower sides of the main shaft are all connected dynamically, this frictional force causes the moment formed by the moving cone to make a yaw movement around 0'0 while also performing the opposite rotation movement. This self-rotation movement can promote more uniform particle size and uniform wear on the moving cone surface.

The gyratory crusher has two kinds of side unloading and center unloading. The side unloading has disadvantages such as large height of the fuselage and easy unloading of the discharging material. Currently, it has basically been eliminated, and the central unloading structure of the low frame is generally produced. The improved impact crusher model can predict the performance under steady state conditions. The model has a series of parameters. The performance of an impact crusher can be described in terms of a classification function, which depends on the impact energy per unit mass, rotor speed, and feed rate.

Hammer Crusher Based on the results of particle dynamics analysis, the impact energy per unit mass of the vertical axis impact crusher is greater than that of the horizontal axis type. The results predicted by the model are basically consistent with the experimental results. The parameters that are assumed to be constants are functions of impact energy and feed rate, and they are expressed by a suitable formula, and good results are obtained.
