Reversible Crusher Design
Abstract：The specification of the design is the Reversible crusher design, and it mainly contents: the institutional design of the rotor; plate hammer structural design; plate counterattack design.
The design starts from the specifications of the rotor, and it references the relevant parameters of PFK-1212 crusher. 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. 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 PFK-1212 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.
Key Words：Impact Crusher, content, structure, compute
