Quarry Crusher is mainly used as coarse crusher and medium crusher in mines, building materials, infrastructure and other departments. Jaw crusher work part of the machine is two piece of board, a fixed jaw plate (fixed jaw), vertical (or slightly upper extroversion) fixed in the body on the front wall, the other is a movable jaw plate (jaw), position, form a crushing cavity on the small and fixed plate (Hubei the working chamber). The movable jaw plate periodically moves back and forth towards the fixed jaw plate, sometimes separated and sometimes approached. When separating, the material enters the crushing cavity, and the finished product is unloaded from the lower part; when close to the material, the material which is arranged between the two jaw plates is crushed, bent and split to break.
In the jaw crusher, the static and dynamic plate wear can cause the crusher not to run normally and lose the crushing capacity. The normal production of jaw crusher ensures the normal production of jaw crusher. Extend the Hubei board using noodles, reducing wear method:
The crusher will wear in the course of the work, this kind of wear can be reduced and inevitable, wear will shorten the mechanical life, so as far as possible to reduce. The crusher also wears itself during the processing of the ore.. In order to minimize the loss of parts, it is necessary to adhere to the scientific choice of models; two, the rational use and selection. Once the type selection is improper, the serious will cause the factory long-term production passive, the light person will also cause the frequent multi consumption.
Crushing methods are mixed crushing and pre screening crushing, mixing crushing, refers to the cement production of two raw materials in a certain proportion into a crusher for crushing process. The common mixed crushing is limestone and marl, limestone and shale, limestone and clay. The raw materials are screened before crushing, and the crushing of the sieve is often achieved, and good results can be obtained.
Machine jaw problems: jaw crusher jaw plate and machine contact surface is not smooth; the eccentric shaft speed is too fast, has broken the material not excluded, lead to the crushing cavity blockage, jaw plate wear; changes of material properties, but no crusher to make timely adjustments; the angle between the plate and the movable jaw the fixed jaw plate is too large, more than the normal range; its strength and wear resistance of the jaw plate, the fight against bad performance.
Solution to jaw crusher jaw plate wear: new, jaw plate must be fixed, tight, installed, and the surface of the machine contact smoothly. In the surface between the jaw plate and machine pad a layer of plastic materials used; each batch into the crusher material to sampling, once the material properties have great changes to parameters of crusher change timely, to cooperate with the material into the jaw plate must be chosen; high hardness, wear resistance, fight strong material.
