Mining machinery crusher machine cavity wear, the reason is that the impact liner wear too many factors, such as material hardness, abrasive, particle size, moisture, and broken the amount of material as well as to a material way with the operating conditions. Even if these factors, the crushing chamber shape, with a crusher machine liner wear is not the same.During operation of the crusher premises broken material into the crusher machine parallel area population number up, after a sharp decline. Therefore, parallel to the area subject to intense wear and stone crusher after running a number of days, and parallel area gradually changed.
With the liner wear and crushing cavity outline the extent of changes, the height of the material to be broken along the crushing chamber is distributed more evenly. In the the liner limit wear range, there are changes in the size of the crushing chamber profile, especially late parallel zone no longer exists, the entire cavity shaped entirely lost its original contour.
Feed port size is reduced approximately 1.4 and 1.7 times, up to the amount of material being processed feed port. Parallel area does not exist, the deterioration in the quality of products, crusher production also fell.
In summary, the liner wear unevenly, crushing cavity lose the original shape of the crushing chamber liner low life and crusher technical and economic indicators fell.
