Title Solution of jaw crusher jaw plate wear
Description Mixed crushing refers to the limestone production process in which two kinds of raw materials are fed into a crusher in a certain proportion for crushing. Common mixed crushing are limestone and marl, limestone and shale, limestone and clay, etc. Screening raw materials before crushing, only crushing the screening materials, often can achieve good results. For example, nowadays cement is produced by a new dry process with pre-decomposition, which improves the silicic acid rate in the raw material mixing, and often needs to be mixed with siliceous raw materials. The contact between the jaw plate and the machine surface is not stable; the eccentric shaft rotates too fast to remove the crushed materials, which results in jamming of the crushing chamber and wear of the jaw plate. Material properties have changed, but the crusher has not been adjusted in time; the angle between the movable jaw plate and the fixed jaw plate is too large to exceed the normal range; The strength and wear resistance of the jaw plate are not good.
