The larger size jaw crusher, a block of material, the greater the degree of crushing, jaw withstand greater impact loads. In this case, the choice of material, you should first consider increasing its hardness and toughness in ensuring the jaw premise. Broken different materials (such as granite, quartzite and limestone), jaw material should be different; and higher material hardness, the hardness of the corresponding jaw should also be higher. Movable plate and fixed plate by different ways and wear mechanisms force, the movable plate to withstand greater impact force, therefore, we should first consider the toughness; and given the support plate from the rack, it can give priority to hardness. When selecting jaw material, technical and economic effects should be considered, and strive to achieve quality and cheap, with market competitiveness. Should also consider the reasonableness of its technology, so that the production plant is easy to organize production and quality control. For decades now broken vertical composite uses "more broken and less grinding, energy saving" has been mining, building materials and other industries to pursue. But until the late 20th century complex vertical break performance, vast majority of our business has been in use mineral jaw crusher + cone crusher + technology portfolio mill, mill feed material due to the large size, can only reach around 20mm, restricting the mill increased production, increased energy mill, it is difficult to achieve good economic Vertical Composite broken introduced Xin Li Heavy professional manufacturer (certified), Hainan Vertical Composite broken Gongyi City Xin Li Heavy Machinery Manufacturing Co. available.
