Physical Model for the Motion of Cone Crusher

For the cone crusher, the form of the vibration is quite complicated. Since the whole cone crusher is installed on the isolation mounting of the spring, the outer crushing cone has four degrees of freedom, two horizontal degrees of freedom and two degrees of torsion. In the crushing cavity, the inner crushing cone moves horizontally around the outer crushing cone. Since the particle size of the material particles is different, the thickness of the material layers is not even. When the inner crushing cone slides around the material layer, with the change of the thickness of the material layer and the extrusion and impact, innumerable additional weak pulse ripple with different size will appear. The pulse ripple makes the cone crusher produce the additional vibration so that the vibrating form of the crushing system of the cone crusher becomes more complex.
When you establish the double plastid vibration crushing mechanics model, you have to consider the vibrating effect of the material layers. The material layer plays the role to store the energy and absorb the energy in the crushing process. In order to more clearly describe the dual plastid vibration system, the experts of Henan Hongxing Mining Machinery have showed the simplified system mechanics model.
In the double plasmid model, the piecewise linear and the nonlinear hysteretic force can be used to express this action. There is slight gap between the spring and the crushing cone. There will be gap only in the special case or when the filling rate of the materials in the crushing cavity. If the space distribution of the material layer is even, the hysteretic force is symmetrical about the original point of the displacement.
Before studying the two freedom degree double plastid mechanics model, we must have a better understanding about the crushing equipment. The study on the two freedom degree double plastid mechanics model is very important in the actual use of the cone crusher, which may help us better use the cone crusher.
