Jaw Crusher of main components

1. Rack

Up and down the walls of the opening frame is rigid framework for supporting the eccentric

shaft and bear fragmentation reaction of materials, require sufficient strength and

stiffness, which is often cast as a whole cast, minicomputers can also be used instead of

high-quality cast iron steel. Sub-rack mainframe be cast, and then bolt firmly linked into

the overall, complex casting process. Made a small jaw crusher frame welded thick steel

plate can also be used, but less stiffness.

2. Jaw plate and side plate protection

Fixed Jaw Crusher and movable jaw by the jaw

and the jaw plates bed, regardless of jaw plates is working with the wedge bolt and fixed to

the jaw on the bed. Jaw jaw is fixed rack anterior bed, moving bed jaw jaw hanging Week, to

have sufficient strength and rigidity to withstand the crushing counter-force, so most of

steel or cast iron.

3. Transmission Parts

Eccentric shaft is broken machine spindle, torque curve by a huge, high carbon steel.

Eccentric part of the required finishing, heat treatment, the bearing liner with Babbitt

pouring. Eccentric shaft pulley mounted at one end, other end of the flywheel installed.

4. Adjuster

Conditioning installations wedge, plate type and the hydraulic type, and so, generally

wedge, wedge formed by the front two, the former wedge can move easily withstand push back

plate; wedge after the wedge for the adjustment can be up and down Mobile, two backward

fitting wedge ramp, wedge, after the screw to move up or down to adjust the size of the

discharge port. Small jaw crusher discharge port after the change in regulation is the use

of thrust plate bearings and gasket between the frame number to achieve.

5. Flywheel

Jaw crusher jaw 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. Cast iron or cast steel wheel manufacturing often, the minicomputer often made

integral flywheel. Flywheel manufacture, installation, pay attention to static balance.

6. Lubrication Device
Eccentric shaft bearing lubrication cycle usually concentrated. Spindle and thrust plate

bearing 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 open a

number of axial bearing oil groove bottom, the middle part of the tank open so connected,

and then forced into the dry butter oil pump lubrication.

This series of products, great crushing ratio, even granularity, simple structure, reliable

operation, easy maintenance, less operating cost and so on. Widely used in mining, smelting,

building material, highway, railway, water conservancy and chemical industry and other

industries, breaking strength no more than 320 MPa of various materials.

PE, PEX series jaw crusher is a complex swing crusher for metallurgy, mining, construction,

transport, cement and other sectors, as thick broken, the breaking strength in 300Mpa

following use of various ores or rocks. Simple structure is reasonable, high output, broken

than large, long life tooth plate, finished with uniform size, low consumption power,

maintenance and easy maintenance, etc. You Dian, is currently the most advanced models.

The series crusher broken song moving

squeeze-type way, its working principle is: motor-driven belt and pulley, through the

eccentric axis to move the jaw up and down, up when the movable jaw plate and movable jaw

when the elbow angle between the larger, so promote the movable jaw plate close to the fixed

jaw plate, while the material is crushed or split pieces to achieve the purpose of crushing;

when the movable jaw down, the elbow angle between plate and moving jaw smaller, movable jaw

plate in the bar, spring under the influence, leaving the fixed jaw plate, this time has

been broken under the mouth of materials discharged from the crushing chamber. With the

continuous rotation motor for periodically broken jaw mobile crushing and waste materials,

to achieve mass production
