Jaw crusher system components

Jaw crusher system components

Jaw crusher is a mechanical equipment broken materials, machinery production line is commonly used in one of the equipment, widely used in mining, smelting, building materials, roads, railways, water conservancy and chemical industries in a variety of minerals and bulk materials broken.

1. Rack

Rack is the upper and lower openings of the four-wall rigid frame, used to support the eccentric shaft and withstand the reaction of broken material, requires a sufficient strength and rigidity, generally cast steel casting, minicomputer can also use high-quality cast iron instead of cast steel. Mainframe frame to be sub-cast, and then firmly linked into a whole bolt, casting process is complex. Homemade small jaw crusher frame can also be welded with thick steel plate, but the stiffness is poor.

2. Jaw plate and side panels

Fixed jaw and moving jaw are composed of jaw and jaw plate, jaw plate is part of the work, with bolts and wedge fixed in the jaw bed. Fixed jaw jaw bed is the rack front wall, moving jaw jaw bed hanging in the week, there must be sufficient strength and rigidity to withstand crushing reaction, which are mostly cast steel or cast iron.

3. Transmission parts

Eccentric shaft is the main axis of crusher, by a huge bending torque, the use of high-carbon steel manufacturing. Eccentric part of the need to finish processing, heat treatment, bearing lining with babbitt casting. One end of the eccentric shaft pulley, the other end of the flywheel.

4. Adjustment device

Wedge type, wedge type, wedge type, wedge type, wedge type, wedge type, wedge type, wedge type, wedge type, wedge type, wedge type and wedge type Move, the wedge of the slope of the backward fit, by the screw to move up and down after the wedge to adjust the discharge port size. Small jaw crusher out of the mouth adjustment is to increase or decrease after the thrust plate bearing between the frame and the number of pads to achieve.

5. Flywheel

Jaw crusher flywheel to store the energy when moving the jaw empty stroke, and then used for industrial formation, so that the work of machinery in line with the uniform. The pulley also functions as a flywheel. Flywheel often cast iron or cast steel manufacturing, minicomputer flywheel is often made of integral type. Flywheel manufacturing, installation should pay attention to static balance.

6. Lubrication device

Eccentric shaft bearings are usually concentrated circulation lubrication. The bearing surfaces of the mandrel and the thrust plate are generally greased by means of a manual oil gun. Moving jaw swing angle is very small, so that between the spindle and the bearing lubrication difficult, often in the bottom of the axle bearing a number of axial oil groove, the middle of a ring to the oil tank to connect, and then forced into the dry oil pump lubrication.
