Zhongxin Heavy Industry cone crusher can be used in building materials industry, road construction industry, chemical industry and silicate industry. It is suitable for crushing various ores and rocks with medium and medium hardness. Simmons cone crusher has a series of advantages such as large crushing force, high efficiency, high processing capacity and low operating cost.

Mining crushers will face wear and tear, especially the crushing cavity of cone crushers. What are the conditions that affect the wear of the crushing cavity? Among them, the material hardness, abrasiveness, particle size, moisture, etc. will affect the wear of the crushing cavity, and the wear of the same material will be different for different cavity types.

During the operation of the crusher, the number of crushed materials entering the population in the parallel area of ​​the crusher was the largest, and thereafter it dropped sharply. Therefore, after the parallel zone is strongly worn and the crusher has been operated for several days, the parallel zone gradually changes.

With the wear of the liner and the degree of change in the contour of the crushing cavity, the material that is crushed along the height of the crushing cavity is more evenly distributed. There are changes in the contour size of the crushing cavity within the limit wear range of the liner, especially the parallel zone no long exists in the later stage, and the entire cavity shape completely loses its original contour. At this time, the size of the feeding port is reduced by about 1.4-1.7 times, and the amount of materials processed by the feeding port is the largest. Because the parallel zone does not exist, the quality of the product deteriorates, and the output of the crusher also decreases.

To sum up, due to uneven wear of the liner, the crushing cavity loses the shape of the original crushing cavity, resulting in a low liner life and a decline in the technical and economic indicators of the crusher.
