The two cone shape of gyratory crusher are in steeply inclined, the movable cone is erect frustum cone ,and fixed cone is headstand frustum cone, which is mainly used to magnify the feeding end. The two cones of medium and fine cone crusher are both gentle dip erect frustum cones, and between the two cones, there is a certain length parallel crush section (parallel band), which is used to control the granularity of product, for the design of medium and fine crusher is based on the quality and capacity of crusher.
Impact crusher main shaft assembly is composed of bearing seat, main shaft, bearings and other components.
Impact crusher impeller is a hollow cylinder made of special material, it is mounted on a spindle assembly end head, cone sleeve and binding transfer torque, high rotating speed impact crusher impeller is the key components, the material enter into the impeller from the upper wheel feeder central feeding tube, central cloth cone allocate to the each emission stream crossing on average, Head cast material is equipped with special material and can be replaced.
Impeller material will be projected out when it is accelerated to 6075 M / s, it first form an impact with waterfall materials, and then hit the eddy lining and lining again. A channel plate is provided between the conical cap and polishing material, protecting impeller from wearing.
Grinding and classification
In the ore mining factory, grinding operation is falling behind the crushing processing. However, this operation continues crushing processing to ore is an important part of the ore separation. The quality of the grinding product has direct impact on the level of the choosing index. The combination of grinding machine and classifier grinding process is called a ore-milling classification process. The grinding process should make its final product size up the following operation needs. Besides, the grinding process should be simple, flexible and has certain adaptability. The main grinding process equipments are ball mill, grate ball mill, wet grinding machine, Raymond mill, autogenous mill, semi-autogenous mill and spiral classifier, etc.
