The Design Of The PF-1318 Impact Crusher Rotor 

Abstract：   The design starts from the specifications of the rotor, and it references the relevant parameters of PF1318 crusher. Initially it sets the rotor speed, so that I can design the board hammer size, number and other relevant data with the rotor speed. Productivity and size of the crushed materials should be ensured before the overall structure of the design finished, according to the whole structure, I could determine the design of all the major components of the design. 

 The design of the main components includes pulley design calculation, the structural design of shaft, bearing selection, design and calculation of the rotor components, board structure and a fixed hammer, crushing chamber design and the design of computing counter devices and so on. One of the most important parts is the rotor design and board design and the fixed method of hammer. In order to increase the stiffness of the rotor, the rotor body is combined with ZG340 material, and it casts with the whole body. Board hammer is fixed with bolts, and use of new materials could enhance their wear resistance and utilization. Finally, I illustrate the installation, repair and maintenance of impact crusher, which is essential to improve their life. 

 The overall design further improves its crush performance which is based on the impact crusher of the PF1318 model. Moreover, it exits advantages such as simple structure, light weight, small dimensions, low cost of equipment, operation safety, convenient operation, easy maintenance and management.
