Jaw crusher is mainly used for crushing various ores and large materials with compression strength not more than 320Mpa into medium-sized grains;and is widely applied in mine, metallurgy, construction, road, railway, water conservancy, chemical industry, refractory material and ceramic etc.
Working Principle of Jaw Crusher
This crusher adopts the electric motor as the power. The eccentric shaft is resolved by an electric motor through v-belts. It causes the swing jaw following the pre-concerted 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.
Again, jaw crusher impact load bearing on the babbitt lining, duration of work for about two years or so, the deadline, you will need to re-cast. If the eccentric shaft and bearings, spindle and bearing wear, the tip clearance is 1.5 times larger than the original assembly gap, the need to increase the pad adjustment or replacement; oil ditch wear of 1.5 mm, oil groove and adjustments should be re-opened. The gap between the connecting rod head cover and the eccentric shaft, wear and tear is greater than 1.5 times the assembly gap, also need to add a pad to adjust or replace. Babbitt bearing on deep peel or larger abrasions should be re-cast. Bearing quality processed the following requirement: babbitt surface should be uniform in color, luster, silver-white; babbitt surface layer should not be ash, cracks, sand holes, shrinkage and peel phenomenon.
