The crusher can not be broken. What happened to the stone?
Within a certain range, increasing the eccentricity of the eccentric shaft can increase the capacity of the crusher, but it also increases the energy consumption of the crushing unit weight of the ore.. The speed is too large, will have been broken in the crushing chamber of the ore to discharge, and blockage phenomenon, but to reduce production capacity, power consumption increases, therefore, there should be a jaw crusher optimum rpm.
Due to improper use can often cause the phenomenon of death, so in the crusher, crushing the material, must pay attention the degree of uniformity of the material, there is the hardness of the material properly, if perfect, drum type drying machine, can add a working procedure.
Generally, the main factors that affect the crushing capacity of jaw crusher are meshing angle and revolution.The angle of engagement is the angle between the moving jaw and the fixed jaw. According to the calculation, the maximum angle of contact can reach 32 degrees. The actual use is less than 25 degrees, generally about 1820 degrees. The angle of contact is too large to crush the ore in the crushing cavity so that it hurts or damages other equipment, while the productivity decreases as the Jiao Zengda (crushing ratio increases). Adjust the size of the ore discharge, and also change the size of the angle of engagement. In actual life, the size of ore discharge is regulated according to the size of ore discharge. Therefore, it is reasonable to enlarge the discharge gate as much as possible to ensure the product granularity. The size of the ore discharge can be adjusted by adjusting blocks, and the relation between crushing ratio and productivity should be paid attention to when adjusting the ore discharge.
