Specific analysis on the crushing chamber wear of the crusher

Wear crusher cavity, which liner wear because many factors affect such as material hardness, grinding, particle size, moisture and the amount of crushed material and the feeding mode and the operating conditions. Even if these factors are the same, the wear of the liner is different for the same crusher due to the different shape of the crushing cavity. The wear analysis of the crushing chamber of the 1750 fine crusher is as follows.

During the start of the operation of the crusher, the number of broken materials entering the population of the parallel area of ​​the crusher was the highest, and then dropped sharply thereafter. Therefore, the parallel zone is subjected to intense wear and the parallel zone gradually changes after several days of operation of the crusher.

As the lining wears and the contour of the crushing chamber changes, the material that is broken along the height of the crushing chamber is more evenly distributed. There is a change in the size of the crushing cavity in the limit wear range of the lining plate, especially the late parallel region does not exist, and the entire cavity shape completely loses the original contour. At this time, the size of the feed port is reduced by about 1.4-1.7 times, and the amount of material processed at the feed port is the largest. As the quality of the product deteriorates due to the absence of parallel zones, the crusher production also decreases.

In summary, due to the uneven wear of the lining, the crushing cavity loses the shape of the original crushing cavity, resulting in low life of the lining and a decrease in technical and economic indicators of the crusher. Therefore, the crusher cavity of this crusher should be improved.
