| 摘要 |
A wear part for a mineral material processing apparatus includes an outer wear surface which includes an initial phase wear surface to be put in crushing contact with an opposite wear surface, and an end phase wear surface to be taken vertically into use in the crushing process from under the initial wear surface when the wear is progressing. The wear part includes an end phase wear surface with a protrusion to be put in use when the wear of the outer wear surface is progressing. By means of the protrusion, the working life of the wear part can be prolonged. A mineral material processing apparatus and a mineral material processing plant is also disclosed. |
