Analysis of Design and Calculation of Impact Crusher

Theoretically, the yield of the coarse impact crusher can be calculated according to the crushing materials produced through one circle of the rotation of moving cone. In fact, the amount of the discharging material in the unit time not only relates to the size of the circle, but also relates to the density degree of the material. Obviously, this assumption does not fully reflect the actual situation. To this end, in the actual production, we usually use some empirical formula for calculation. The crushing process of the impact crusher is similar to the crushing process of the jaw crusher. Therefore, the calculation method of the jaw crusher still can be used in the calculation process of the coarse impact crusher. The derivation method of power needed by the coarse impact crusher in the theory is basically similar to that of the jaw crusher.
At present, the domestic calculation for the strength, rigidity, abrasion resistance, and the stability of the main components of the impact crusher is not perfect yet. Therefore, in the design calculations, we should still use the design methods of the heavy machinery and general machinery parts to do the design calculations of the impact crusher. There are major three parts for the design and calculation of the impact crusher. This parameter is the structural parameter required by the process of the impact crusher. The ores are fed into the impact crusher through the conveyor belt. The ores through the ore dividing plate do not directly fall in the ore mouth. Therefore, the circle space formed by the ore dividing plate and the fixed cone should not be stuck by the large pieces of the ore. The cone angle of the material hopper should be determined by the liner of the moving cone.
