PF-1620 impact crusher housing design
Abstract：This article introduces the PF-1620 Impact crusher chassis body design content. This article describes in detail the classification of the crusher, the advantages and disadvantages, purpose and use of the occasion. Mainly from the impact crusher works, the body construction, design and other aspects of this design done in detail. In program design, from the material point of view, to analyze and compare the three programs, and ultimately determine the optimal solution. After completing the plan was finalized, it has been designed for cabinet structure. The main components and strength check and calculation, mainly flat key connection for the crusher, the rotor shaft strength, bearing selection, ground screw of checking calculations. Strength formula for use of check and make bending moment diagram and torque diagram to illustrate.
