Method of reducing wear during use of jaw crusher

Problems in using jaw crusher The contact between the jaw plate and the surface of the machine is not stable; the eccentric shaft rotates too fast, and the crushed materials can not be removed, which causes the crushing chamber to be blocked and the jaw plate to be worn; the properties of the materials have changed, but the crusher has not made timely adjustment; the included angle between the movable jaw plate and the fixed jaw plate is too large, which exceeds the normal range; the strength, wear resistance and resistance of the jaw plate Not good To solve the abrasion of jaw plate of jaw crusher, the newly installed jaw plate must be fixed tightly, installed well and contact with the surface of the machine smoothly A layer of material with good plasticity can be padded between the jaw plate and the surface of the machine; each batch of materials entering the crusher shall be subject to sampling inspection Once the material property changes greatly, the parameters of the crusher shall be changed in time to make it match with the entered materials; the jaw plate must be made of materials with high hardness, wear resistance and strong resistance; the mining crushing production line technology shall be possessed The same type of worn jaw plate of mine coarse crushing and cement fine crushing can be interchanged in cement enterprises, and the worn jaw plate can be repaired by overlaying In addition, attention shall be paid during the working process: the crusher can be put into operation only after normal operation; the crushed materials shall be evenly added into the crushing chamber to avoid side feeding or stacking to prevent unilateral overload or overload; under normal conditions, the temperature rise of bearing shall not exceed 35 ℃, Zui high temperature shall not exceed 70 ℃, if it exceeds 70 ℃, the machine shall be shut down immediately to find out the cause and eliminate it In addition, before the shutdown, the feeding work shall be stopped first, and the motor can be closed only after the crushing chamber is completely discharged from the crushing chamber; during the crushing, if the shutdown is caused by the blocking of materials in the crushing chamber, the motor shall be closed immediately, and it can be started only after the materials are removed; after one end of the toothed plate is worn, it can be used in a reversed way.
