Reversible Crusher Design
Abstract：The specification of the design is theReversiblecrusher design,
And it mainly contents: the institutional design of the rotor; plate hammerstructural design; plate counterattack design.
The design starts from the specifications of the rotor, and it references the relevant parameters of PFK-1212 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 in the article introduced a new Reversible crusher beyond the traditional one, It highlighted the working principle of Reversible crusher, and through the main parts of the strength calculation which optimized the overall structure of the Reversible crusher, moreover, analyzed its advantages and disadvantages and application, and then Reversible crusher of the whole structure was improved design, which is mainly improved rotor design and material selection of nutation reasonable parameters, also can shorten the product development cycle and improve product reliability. Finally, described the operation installation maintenance of the entire machine minutely. Maybe can provide a reference of the use and preparation for coal enterprise.
