Jaw crusher is a relatively common type of crushing equipment, jaw broken power is small, strong crushing capacity, suitable for all kinds of rock crushing, commonly used in mining, smelting, building materials, highway, railroad, water conservancy and chemical industry and other industries. So do you understand the structure of jaw crusher, Jaw Plate Manufacturers -SHANVIM will give you a detailed introduction to the main components of jaw crusher.
1.Frame
The frame is a four-wall rigid frame with upper and lower openings, which is used to support the eccentric shaft and bear the reaction force of the crushed material, and it is required to have the force performance and rigidity, usually cast steel is used for the whole casting. Small output jaw can also be used to replace cast steel with good cast iron, large capacity jaw crusher frame needs to be cast in sections, and then screws to strengthen the link into a whole, casting technology is complex.
2.Jaw plate and side guards
Fixed jaw and movable jaw are composed of jaw bed and jaw plate, jaw plate is the working part, with screws and wedge iron unchanged in the jaw bed, fixed jaw of the jaw bed is the front wall of the frame, movable jaw jaw bed hanging in the week, to have the force performance and stiffness to withstand the crushing reaction force, and therefore a lot of cast steel or cast iron parts.
3.Driving parts
Eccentric shaft is the main shaft of the jaw crusher, subject to bending torsion, the use of high-carbon steel production, eccentric part of the fine crushing, thermal solution, bearing lining tile with pasteurized alloy casting, eccentric shaft one end of the installation of pulleys, the other end of the installation of flywheel.
4.Adjustment system
Adjustment system has wedge type, pad plate type and hydraulic type, etc. Usually use the wedge type, composed of front and rear two wedges, the front wedge can be moved back and forth to hold the rear thrust plate; the rear wedge is an adjusting wedge, which can be moved up and down, and the beveled surfaces of the two wedges are inverted to fit together, so that the rear wedge is moved up and down by the screw to adjust the size of the discharging opening, and the discharging opening of the small output jawbreaker is adjusted by virtue of the increase or decrease of the number of shims between the support of the rear thrust plate and the frame to reach. The adjustment of the discharge opening of the small output jawbreaker is achieved by increasing or decreasing the number of shims between the rear thrust plate support and the frame.
5.Flywheel
The flywheel of the jaw crusher is used to store the energy of the movable jaw during the empty stroke, so that the load of the jaw crusher is even. The flywheel is often made of cast iron or cast steel, and the flywheel of small output jaw crusher is often made into a whole type. When installing the flywheel, pay attention to the static balance.
6.Lubrication system
Eccentric shaft bearings usually use centralized circulation lubrication, the mandrel and thrust plate support surface usually use lubricant through the manual oil gun oil, the swing angle of the movable jaw is not very large, so that the mandrel and the axial tile lubrication between the trouble, often in the bottom of the axial tile to open if the dry axial oil grooves, the middle of the opening of a ring to the oil grooves so that it connects, and then forced to add a dry grease lubrication with an oil pump.
