According to conventional design methods of various crushers some silly stupid coarse composite rock breaking machine, and some strength insufficient stiffness. Optimize the structure design is our company's recent design guidelines emphasize, is the only way to compete in today's environment of business survival. We are large vertical compound crusher design, finite element method for the first time, the motor bearings are optimized. PF Series Impact Crusher is my company in the absorption of foreign advanced technology composite rock breaking machine classification, combined with mud gravel mining industry specific conditions and the development of the latest generation of composite crusher rock breaking machine performance, the device has a crushing ratio After the material was broken cubic particles, wear parts and long service life, etc., after the user has made to promote the use of the obvious economic benefits. Main purpose: This series crusher is suitable for building materials, mining, metallurgy, chemical industry broken limestone, clinker, coal and other ore crushing operations, but also can be used for dolomite, flint, lead and zinc, serpentine, high slag crushing operations, coal, phosphate rock and other medium hardness of materials, especially for artificial sand or stone pavement highway machining of hard limestone, dolomite, granite, basalt crusher. Its compressive strength of not more than 140 MPa humidity less than 15%. Composite rock breaking machine performance, Hainan composite rock breaking machine, Xin Li Heavy provided by Gongyi City Heavy Machinery Manufacturing Co., Ltd. Xin Li.
