Jaw Crusher main components

1 rack
Rack is opening up and down the walls of the rigid frame, eccentric shaft and used as support material to withstand crushing reaction, small jaw crusher requires sufficient strength and stiffness, usually with a cast steel piece casting, minicomputer can also be used instead of high-quality cast iron steel. Cast to be sub-rack mainframe, and then bolt firmly linked into the whole, casting complex. Made a small jaw crusher frame welded thick steel plate can also be used, but less stiffness.
(2) jaw plate and side guard
By the fixed jaw and movable jaw jaw jaw bed and board composition, board is working, regardless of the jaw, with bolts fixed to the jaw and wedge iron bed. Fixed jaw jaw is rack anterior 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 broken machine spindle, bent by a huge 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
There are wedge-style adjustment device, plate and hydraulic, etc., generally wedge-type, two wedge formed by the front and rear, front wedge can move, stand up push plate; to adjust the wedge after wedge, can be up and down mobile, two wedges fit slope backward from the screw to move up or down to adjust the wedge after the discharge port size. Small jaw crusher discharge port after the adjustment is to use changes in the thrust bearing plate gasket between the frame and how much to achieve.
5. Flywheel
Jaw crusher jaw moving flywheel to store energy during air travel, and then used in industry to form, so that mechanical work is in line uniformly. Flywheel pulley also plays a role. Flywheel often cast iron or cast steel, minicomputers, often made of the overall style of the flywheel. Flywheel manufacturing, installation, pay attention to static equilibrium.
6 lubricating device
Eccentric shaft bearing lubrication cycle is usually concentrated. Spindle and the thrust plate support surface generally use the grease gun oil to the oil by hand. Moving jaw of the pendulum angle is very small, between the spindle and bearing lubrication difficulties, often in the opening number of the axial bearing oil groove bottom, the middle part of open connecting to the tank so, then pumps force the butter into the dry lubrication.
This series of products, with a 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, crushing compression strength not more than 320 MPa of various materials.
PE, PEX series jaw crusher crusher swing is a complex device, used in metallurgy, mining, construction, transportation, cement and other departments, as rough broken, broken in 300Mpa the following compressive strength of various minerals or rocks purposes. Has a simple structure, high output, broken than large, long life gear plate, finished uniform size, low power consumption, easy maintenance, etc., is currently the most advanced models.
This series of crusher, squeeze-type dynamic way for the song, its working principle is: Motor drives belt and pulley, the eccentric shaft to move up and down jaw movement, rises when moving jaw toggle plate and moving jaw angle between the larger, and thus push moving jaw plate close to the fixed jaw plate, while the material is crushed or split pieces, broken to achieve the purpose; down when moving the jaw, the toggle plate and moving jaw angle between, moving jaw plate rod, spring under the effect of leaving the fixed jaw plate, this time under the broken material from the crushing chamber discharge port. With the motor for rotating the motor broken jaw periodically for crushing and waste material, to achieve mass production.
