The jaw crusher is widely used in the industries of mining, metallurgy, chemical engineering, building materials, water conservancy, transportation; etc. it is one of the most widely used mineral processing equipment that is mainly used in the crushing of ore materials in sand production line, beneficiation production line, jaw crusher is the best choice for coarse crushing and fine crushing of materials, the routine maintenance of crusher can guarantee the steady and favorable operation of equipment. In order to have a good maintenance of the equipment, a better understanding of the structure of the equipment is very essential. DSMAC (Ding Sheng Machinery) will give you a detailed introduction of the six main components of jaw crusher.

1. Transmission parts

Eccentric shaft is the core crusher shaft, by the force of a huge bend torque, made by high-carbon steel. Eccentric part of the required finishing, heat treatment, bearing with Babbitt lining tile cast. Eccentric shaft pulley mounted at one end the other end mounted flywheel.

2. Racks

Up and down the walls of the opening frame is rigid framework for supporting the eccentric shaft and the crushing of materials to withstand the reaction, requires sufficient strength and stiffness, usually with a cast the whole cast, minicomputer can also be used instead of high-quality cast iron steel. Cast to be sub-rack mainframe, and then link into the overall solid bolt, casting complex. Made small jaw crusher frame welded thick steel plate can also be used, but less stiffness

3. Jaw plate and side guard plate

Set jaw and swinging jaw are composed by jaw plate and guard plate, jaw plate is fastened to jaw bed by bolt and drift. The jaw bed of set jaw is anterior part of racks. Swinging jaw bed is hanging in the around, who must has enough strength and stiffness to bear the counter-force of crushing.

4. Flywheel

The flywheel of jaw crusher is used for store the energy while the swinging jaw is moving, and then used in industry form, so that the mechanical work is well-distributed. Flywheel is mainly used for cast iron and cast steel, while the flywheel of mineral machine is usually unitary. Static balance should be paid attention to when making and setting up the flywheel.

5. Lubricating device

Eccentric shaft bearing lubrication cycle is usually concentrated. Spindle and thrust plate support surface generally use the grease gun oil to the oil by hand. Jaw of the swing angle is small, so that between the spindle and bearing lubrication difficulties, often in the opening number at the bottom of the axial bearing oil groove in the middle to open a ring connected to the tank to make it, then pump to force the butter into the dry lubrication.

6. Regulating equipment

Regulating equipment has wedge type, plate and hydraulic, etc., generally wedge-style, the wedge formed by the front two, the first wedge can move, push plate to withstand; wedge after wedge is adjustable, up and down Mobile, two backward slant wedge fit, after the screw so that the wedge moved up and down to adjust the size of the discharge port. Small jaw crusher discharge port after the adjustment is to use changes in the thrust bearing plate between the gasket and rack number to achieve

The jaw crusher that produced by DSMAC features simple structure, excellent strength, high crushing efficiency, reliable performance, easy overhaul and maintenance, and low production and construction cost. The good quality and service of DSMAC enjoys a good reputation among its customers at home and abroad.
