Jaw crusher structure performance characteristics of the working principle

Jaw crusher for short jaw broken, for the compressive strength of less than 320 MPa of various minerals and large pieces of material of medium size crushing. Jaw crusher is mainly used in mineral processing, mining, metallurgy, cement, building materials, refractories, ceramics, glass, chemicals, railways, water conservancy, highway, silicate and other industries. Its structure is simple and reasonable, high yield, crushing ratio, tooth plate long life, uniform particle size, low power consumption, easy maintenance, and other advantages, won the majority of users trust. Jaw crusher with PE and PEX two series. Among them, PE series jaw crusher is mainly used for coarse crushing, PEX series jaw crusher is mainly used in the broken and crushing.

Jaw crusher structure performance characteristics of the working principle

Jaw Crusher Structure:
  The jaw crusher is mainly composed of frame, eccentric shaft, big pulley, flywheel, movable jaw, side guard, bracket, rear bracket of bracket, gap screw, return spring, fixed jaw and movable jaw. Brackets also play a role in insurance.
Jaw Crusher Features:
1. Crushing chamber deep and no dead zone, increased feed capacity and production;
2. Crushing ratio, product size uniformity;
3. Gasket-type discharge port adjustment device, reliable and convenient, a large adjustment range, an increase of equipment flexibility;
4. Lubrication system is safe and reliable, easy to replace parts, maintenance workload is small;
5. Simple structure, reliable operation, low operating costs.
6. Energy-saving equipment: stand-alone energy-saving 15% to 30%, more than double the energy-saving system;
7. Discharge port adjustment range, to meet the requirements of different users;
8. Low noise, less dust.
Jaw Crusher works:
  Jaw crusher crusher crushing type, motor driven belt and pulley through the eccentric shaft to move the jaw up and down movement, when the moving jaw up when the bracket and the moving jaw angle between the larger, so as to promote the moving jaw to the jaw When the moving jaw down, the bracket and moving jaw angle between the smaller, moving jaw plate in the rod, spring, under the action of the jaw to leave the fixed jaw, rubbing, crushing, and so on, Plate, at this time has been broken material from the crusher cavity under the discharge, with the motor continuous rotation crusher jaw for periodic crushing and nesting, to achieve mass production.

Jaw crusher structure principle

Jaw crusher mainly consists of frame, movable jaw, eccentric shaft, jaws, brackets and other components, V-belt drive motor through the eccentric shaft to make the movable jaw in accordance with the track motion has been tuned so that the machine chamber the material to be broken.

Jaw crusher structure principle

The frame is welded structure, rack mounted before the fixed jaw plate, side walls of crushing chamber is equipped with side guards to prevent sidewall wear.
Movable jaw cast steel body, front mounted movable jaw, the upper portion by the eccentric shaft and roller bearings hanging on the rack, lower support plate in the elbow, and was rolling contact therewith, the eccentric shaft at both ends with a flywheel , pulleys, brackets the other end of the support in the adjustment of the seat and was rolling contact therewith, except bracket play supporting role under load sudden increase plays a role in the insurance of foreign material into the hole can not be broken cavity, that is, since the rapid fracture to protect other components are not damaged.
Adjust the seat mounted on the slide grooves on both sides of the frame, adjusting plate for adjusting the size of the material, when transferred to a size matching a corresponding pad of the pad.
Fourth, the installation instructions
The machine is supplied from the factory assembly machine users should check the receipt of the machine, to remove transport may produce ills.
1, due to the work of the machine vibration is large, it should be installed on a concrete foundation, to reduce vibration due to vibration and impact of the building foundation, preferably in the middle of the machine with the base mat of wood, tape, or other cushioning material.
2, caused significant basis desirability 5-10 times its depth less than the depth of freezing ground, machine installation and foot location can refer to the foundation plan.
3, before the nesting population adjustment, first loosen the plug * bolts, tighten the bolts before adjustment decrease pad, the pad loose back after a good adjustment bolt, bolt fastening plug * Do not let the long-term adjustment bolt force.

Granite jaw crusher structure and Way to work

Broken jaw structure of the main frame, eccentric shaft, big belt pulley, flywheel, moving jaw, side guard, elbow board, elbow boards back seat, adjusting screw gap reset spring, fixed jaw plate and movable jaw plate and other components, wherein bracket also play a role as insurance.

Granite jaw crusher structure and Way to work

Jaw Crusher is electric motor powered by electric motor pulley by the belt and sheave drive eccentric shaft, so that the jaw predetermined trajectory to reciprocate, which will enter the fixed jaw plate, movable jaw plate and side guard plates crushing cavity material to be broken, and through the lower nesting material discharge port will be finished. This series of jaw crusher broken song moving extrusion type, motor-driven belt and pulley, through the eccentric shaft to move the jaw up and down movement when moving jaw rises between toggle plate and moving jaw angle larger, thus promoting the movable jaw plate close to the fixed jaw plate, at the same time the material is squeezed, rubbing, grinding, such as multiple broken; when moving jaw downlink, between toggle plate and moving jaw angle smaller, movable jaw plate to leave the lever under the action of the spring of fixed jaw plate, then the crushed material from the crushing chamber discharge port, with the mobile jaw crusher motor for continuous rotation of the crushing and nesting periodicity to achieve mass production.
