PEX-150×750fineJaw-fashioned Crusher
Abstract：The domestic use jaw type breaker type are very many, But common traditional duplicate pendulum Jaw-fashioned Crusher. The duplicate pendulum jaw type breaker appearance had more than 140 years history, And consummates and the improvement unceasingly after the people long-term practice, Its structure pattern and the organization parameter are day by day reasonable, The structure simple, the manufacture is easy, the work reliably, the service convenient, therefore in profession use and so on the metallurgy, mine, building materials, chemical industry, coal is extremely widespread. Along with the modernized development, various industry sector further grows to the broken crushed stone demand, studies the duplicate pendulum Jaw-fashioned Crusher to have the very vital significance. This graduation project mainly is for meets the production need: Feed head size: ; Discharge hole size: ; Feeding block greatest size: ; Output: .Mainly studies the duplicate pendulum Jaw-fashioned Crusher the movement analysis, V belt choice, the analysis which the Jaw-fashioned Crusher, the toothed rack wears, each kind of operational parameter choice, operating mechanism optimization. Key research transmission design and system optimization.
