The working part of the cone crusher is two truncated cones, one is a fixed cone (also called an outer cone) and the other is a moving cone (also called an inner cone). In the portion of the moving cone close to the fixed cone, the material is pressed, impacted and bent by the moving cone to become the crushing cavity; when the moving cone is offset from the fixed cone, the broken material is discharged under the self-weight at the bottom of the cone , becomes the discharge port, and the…

From the physical phenomena and geometrical characteristics of ore crushing and ball mill grinding process, grinding is the continuation of crushing ore, which is a process of reducing the size of a nugget or ore. However, from the thermodynamic point of view, grinding is a process of internal energy increase. The grinding machine works on the ore block and overcomes the cohesion of the ore block to break it. Therefore,…
