Understanding The System Composed Of Jaw Crusher

Jaw Crusher

As we all know, it is a jaw crusher machinery crushing of materials, machinery production line is one of the commonly used equipment, widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry in a variety of ores and Block medium-grained materials broken. Maximum compressive strength of the material to be broken does not exceed 320MPa, generally used for the first break. The main part of it, what does?
1. Rack
Rack is a rigid frame up and down the walls of the opening, serving as a support reaction force of eccentric shaft and withstand the crushing materials, require sufficient strength and rigidity, generally with the whole cast steel, minicomputer also available quality cast iron instead of steel. Mainframe rack need segmented cast, then bolt firmly linked together into a whole, the casting process is complicated. Rack made small jaw crusher can also be used thick steel plate welded but rigidity poor.
2. jaw plate and side guards
Fixed jaw and movable jaw by jaw bed and jaw plates, jaw working portion is fixed to the bed with a jaw and wedge bolts. Fixed jaw jaw bed is rack anterior wall, moving jaw jaw bed hanging in the week, have sufficient strength and rigidity to withstand the crushing reaction force, which is mostly cast steel or cast iron.
3. Transmission Parts
Crusher eccentric shaft is the main shaft by a huge bending torque, high-carbon steel. Eccentric portion to be finishing, heat treatment, bearing metal with babbitt pouring. One end of the eccentric shaft mounted pulley, and the other end mounted flywheel.
4. The adjustment means
There wedge adjustment device, plate and hydraulic, etc., commonly used wedge from before and after the two wedge composed of former wedge can move back and forth, back against the push plate; wedge after wedge is adjusted, up or down mobile, two wedge ramps Backward bonded by the wedge moved up and down after the screw is adjusted so that the size of the discharge port. Small jaw crusher discharge port to adjust the shim between the thrust plate bearing the rack after use to achieve the number decrease.
5. Flywheel
Jaw crusher flywheel energy storage for air travel when moving jaw, and then used for the formation of industrial, mechanical work is in line tends to be uniform. Also play a role of a flywheel pulley. Flywheel often cast iron or cast steel, minicomputers flywheel often made integral. Flywheel manufacturing, pay attention to the installation of static equilibrium.
6. The lubricating device
Eccentric shaft bearings are usually centralized lubrication cycle. Mandrel and thrust plate bearing surface generally use manual grease gun oil to the oil. Movable jaw swing angle is very small, so that lubrication difficulties between the spindle and the bush, often at the bottom of the pad to open a number of axial oil groove, open in the middle part to the reservoir so that it communicates, and then injected into the dry butter oil pump forced lubrication.
