 Jaw crusher is an important mechanical equipment for crushing ore. The jaw crusher may show some wear during use. In order to minimize the loss of mechanical parts, one needs to insist on scientifically selecting the model; two It is reasonable to use and select materials. Of course, everyone needs to pay attention to the maintenance of the jaw crusher.


 
    Some problems may occur during the use of the jaw crusher. For example, in the structure of the jaw crusher, the wear of the dynamic and static jaw plates can cause the crusher to fail to operate normally and lose the crushing ability; the contact between the jaw plate and the machine surface is not stable; The speed of the eccentric shaft is too fast, and the crushed materials are too late to be eliminated, resulting in clogging of the crushing chamber and wear of the jaw plate; the angle between the movable jaw plate and the fixed jaw plate is too large and exceeds the normal range; the strength and strength of the jaw plate Wear resistance, poor resistance to impact.
 
Jiaozuo zhongxin reminds the majority of users to pay attention to the newly installed jaws must be fixed and tightly installed, and the surface of the machine is in stable contact. A layer of material with better plasticity can be placed between the jaw plate and the surface of the machine; each batch of material entering the crusher must be sampled. Once there is a major change in the nature of the material, the crusher must be changed in time The parameters should be matched with the incoming materials; the jaw plate must be selected from materials with high hardness, wear resistance and strong resistance; the worn jaw crusher jaw plate should be replaced in time.
 
Pay attention to the process of crushing the ore by the jaw crusher. The jaw crusher must be in normal operation before it can be fed; the crushed material should be evenly added into the crushing cavity, and the side feeding or full feeding should be avoided to prevent unilateral Overload or overload; under normal circumstances, the temperature rise of the bearing does not exceed 35 ℃, & the high temperature does not exceed 70 ℃, if it exceeds 70 ℃, it should be shut down immediately, and it should be checked in time; before the shutdown, the feeding work should be s*ped *. After the crushed objects in the crushing cavity are completely discharged, the motor can be turned off.
