Since the inertial cone crusher has very good structural characteristics and dynamics, the inertial cone crusher can be used to meet different process requirements in the processing the ore with different nature. The analysis of the nonlinear vibration condition can deeply reveal the excellent characteristics in order to better guide the production.
The inertia cone crusher is composed of three parts, namely the power parts, transmission parts, and the work part. The vibration condition of inertial cone crusher in the work process is very complex. The vibration condition includes the high frequency slight vibration and the circle vibration in the plane. In the work process, the materials to be crushed suffer from the crushing force in the crushing cavity. In addition, the material vibration is a very important part of the vibration system. The vibration of the actual inertial cone crusher is a kind of two-degree freedom nonlinear vibration.
The first is the hysteresis force analysis. In the motion cycle of the organism of the inertia cone crusher, the hysteresis force is symmetrical, which is a piecewise linear odd function and is symmetrical about the origin point. When the gap of the moving cone of the cone crusher is larger than the loose degree of the materials in the crushing cavity, the moving cone begins to load, the accumulation of stress and strain increases in the material layer, which is in the elastic deformation stage. When the relative displacement of the moving cone reaches the limits of displacement, the crusher machine is in forward unloaded state. The hysteresis force will finally be reduced to zero. Since the working process of the crusher machine is periodic and symmetrical, the motion situation is similar to the previous analysis.
The second is the hysteresis force equation. Since the hysteretic force is symmetrical about the origin of coordinates, you can use the displacement and velocity of the moving cone establish the hysteretic force equation. From the calculation of the equation, we can know the actual vibration frequency of the crusher not only relates to the frequency of the vibration exciter, the quality of the machine and the elastic stiffness of the rubber spring, but also relates to the parameters of the materials.
