Jaw crusher structure

1 Rack
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.
2 jaw plate and side plate protection
Determined by the jaw and jaw jaw jaw bed and board composition, board is working part of the jaw, the wedge bolt and fixed to the jaw bed. Jaw jaw is fixed rack wall bed, moving bed jaw jaw hanging in the week, and have sufficient strength and rigidity to withstand the crushing counter-force, which are mostly cast steel or cast iron.
3 Transmission Parts
Eccentric shaft is the crusher shaft, by a huge bend torque, 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.
4 conditioning
Conditioning with 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.
5. Flywheel
Jaw crusher jaw moving flywheel to store energy when the air travel, and then used for industrial form, so that mechanical work is in line uniformly. Also plays a role in the flywheel pulley. Often of cast iron or cast steel flywheel manufactured minicomputers often made integral flywheel. Flywheel manufacture, installation, pay attention to static equilibrium.
6. 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. This series of products, with crushing ratio, even granularity, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics. Widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry and many other industries, does not exceed the compressive strength of 320 MPa crushing various materials. PE, PEX series jaw crusher is a complex swing broken equipment for metallurgy, mining, construction, transport, cement and other sectors, as crushing, the compressive strength in 300Mpa broken ore or rock under a variety of purposes. Has a simple structure, high yield, crushing ratio, tooth plate, long life, uniform product size, low power consumption, easy maintenance, etc., is currently the most advanced models. This series of crusher broken song moving extrusion-type way, its working principle is: the motor-driven belt and pulley, the eccentric shaft so that the upper and lower jaw movement, jaw rises when moving the elbow angle between the plate and moving jaw larger, thus promote the jaw plate close to the fixed jaw plate, while the material is crushed or split pieces to achieve the purpose of crushing; when moving the jaw down, the elbow angle between the plate and moving jaw smaller, moving jaw plate rod, spring under the effect of leaving the fixed jaw plate, this time broken material from the crushing chamber under the discharge port. With the electric motor for rotating the mobile jaw crusher for crushing and waste material periodically, to achieve mass production.
