Reasons for the wear of the crushing cavity of Symons cone crusher
Cone crushers are widely used in machine-made sand and gravel, high-grade highways, railways, water conservancy, airports, construction, cement, refractories, metallurgy and other industries to produce high-quality stones. It is suitable for fine crushing of granite, basalt, limestone, river pebble, cement clinker, quartz stone, iron ore, bauxite and other minerals. The cone crusher is a new type of crusher designed with a new crushing concept. The equipment structure principle is completely different from other crushers such as jaw crushers, hammer crushers, and impact crushers. Its crushing capacity and production capacity are incomparable to other types of crushers.
The reason for the wear of the crushing chamber is that there are too many factors affecting the wear of the liner, such as material hardness, abrasiveness, particle size, moisture, and the amount of material being crushed, as well as feeding methods and operating conditions. Even if these factors are the same, the wear of the lining board is different for the same type of crusher due to the different shape of the crushing cavity.
The analysis of the wear of the crushing cavity of the cone crusher is as follows:
During the operation of the crusher, the amount of crushed materials entering the population in the parallel area of the crusher was relatively large, and thereafter it dropped sharply. Therefore, after the parallel zone is severely 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. In the wear range of the liner, there are changes in the contour size of the crushing cavity, especially in the later period of the parallel zone no longer exists, and the entire cavity shape completely loses the 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. Due to the absence of the parallel zone, the product quality 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.
