subject: About The Suitable Assembling Of Jaw Crusher [print this page] 1. The working principle of jaw crusher1. The working principle of jaw crusher
This crusher adopts the electric motor as the power. The eccentric shaft is revolved by an electric motor through v-belts. It causes the swing jaw following the preconcerted path to crush the feeding material. Thus the material will be crushed in the crushing chamber which is composed of the stationary jaw plate, swing jaw plate and the liner plate. The material is discharged from the lower part of machine that is what you want.
Please carefully examine the fasteners, especially lubrication components and bolts, before the machine is started. Enough oil must be needed on each lubrication component. Fasten the loose bolts, clear the crushing cavity, and then start the machine. During the normal operation, even material feeding is important. Insufficient load or over load is not allowed. Moving jaw plate, fixed jaw plate, side guard plate and roof plate are wearing parts, and much attention should be paid to them.
2. The suitable assembling of jaw crusher
In the assembling, the crushing plate must be firmly stick to the jaw plate, soft metal (such as lead, zinc, etc) was used as gaskets between crushing plate and jaw plate, and must ensure the crushing plate and jaw plate are fixed by bolts. When crusher in working, the crushing plate should not have a loose phenomenon, otherwise, easy to break or worn out, that will decrease the working life of crushing plate. So we must ensure the install of crushing plate during assembling, consequently, make it possible that extend the working life.
3. Extend the working life of crushing plate during use
In the production, crushing plate and material act directly, the power of crushing is big, for example, when crushing material with hardness, maybe bolt of crushing plate will be loosing, which will make the crushing plate worn out and produce noise. If the situation worse, the crushing plate will drop or break off so that make the crusher to stop, the normal production will be affected.
4. Conclusion
For the longer working life of the jaw plate of jaw crusher, we must improve those aspects, such as design and selecting material, assembling, etc, thereby improve the efficiency and decrease the cost.
