Jaw crusher objective and scope

1, the series jaw broken primarily made use of in metallurgy, mining, chemical, cement, construction, refractory and ceramics as well as other industrial sectors for the secondary and tertiary crushing of numerous medium challenging ore and rock with.

2. This series of jaw-breaking best suited to crushing compression strength not greater than 300MPa (MPa) inside a selection of soft and tough ore, the largest block of the material to become broken is just not higher than the technical parameters specified within the table.


1, rack

Rack is really a rigid frame up and down the walls on the opening, the eccentric shaft is made use of as a help and subjected to reaction of broken material, needs adequate strength and stiffness, ordinarily using the whole cast steel, minicomputers can also be employed in location of high-quality cast iron. Cast chassis mainframe segment requires, after which bolt firmly linked within a entire complicated casting procedure. Rack made tiny jaw crusher also can be thick steel plate welded with each other, but poor stiffness.

2, jaws and side guards

Fixed jaw and movable jaw by the jaw bed and jaw plate, jaw is functioning portion, fixed bed inside the jaw and wedge bolts. Jaw jaw is fixed bed frame front wall, moving jaw jaw hanging bed on the shaft, have sufficient strength and rigidity to withstand the crushing reaction force, which can be mainly steel or cast iron.

3, the drive member

The eccentric shaft spindle jaw crusher, torque curve by a huge, high-carbon steel. Eccentric part of any finishing, heat treatment, bearing bush with babbitt pouring. Eccentric shaft pulley mounted at one end plus the other end mounted flywheel.

4, adjusting indicates

There wedge adjustment device, and hydraulic plate, and so forth., generally made use of wedge by wedge consisting of two front and rear, front wedge might be moved back and forth, back against the push plate; wedge right after wedge is adjusted, up or down move backward two wedge ramps match by moving up and down so that the screw wedge adjusted soon after discharge port size. Small jaw crusher discharge port regulation is gasket among the thrust plate bearing the amount of the frame to achieve the enhance or lower right after use.

5, flywheel

jaw crusher

Jaw crusher flywheel to shop power jaw air travel when moving, and then used in industrial type, the mechanical work is in line tends to be uniform, but in addition acts as a flywheel pulley, flywheel frequently cast iron or steel manufacturing, minicomputers normally made of monolithic flywheel, flywheel manufacturing, pay consideration towards the installation of static equilibrium.

6, the lubricating device

Eccentric shaft bearings are often centralized lubrication cycle. Mandrel and thrust plate bearing surface generally use grease gun oil for the oil by hand. Swing angle from the movable jaw is very compact, in order that lubrication in between the spindle and bearing difficulty, often inside the bush in the bottom of the opening quantity of the axial oil groove, open inside the middle of a ring to ensure that it communicates towards the reservoir, after which injected in to the dry butter oil pump forced lubrication.
