Jaw Crusher Working Principle

Jaw Crusher Working Principle


Jaw Crusher Overview

Jaw crusher is appeared earlier and broken instrumentation, its structure is easy, solid, reliable operation, simple maintenance and overhaul likewise because the production and construction prices less, so, heretofore still wide in science, industry, artefacts, electrical power, transportation and different industrial department, general are often divided into pendulum jaw crusher and Jane place 2, primarily used for coarse, medium. In recent years, seemed to finely pendulum jaw crusher and broken high strength, high hardness, low carbon ferrochrome robust jaw crusher. Jaw crusher is wide employed in mining, smelting, building material, highway, railway, water conservancy and industry, etc.

Jaw Crusher Application

Jaw crusher is used for crushing in 147 ~ 245 mpa compressive strength of all kinds of ores and rocks of coarse, medium and fine grinding. Being broken material maximum compressive strength of 320 mpa. Jaw crusher features: jaw crusher broken than large, uniform end product size, simple structure, reliable operation, easy maintenance, low operating costs.

Jaw Crusher Working Principle

When Jaw crusher working, motor through the pulley drive the eccentric shaft rotation, from the period of hubei near, fixed jaw, and for the material such as extrusion, rolling and run multiple broken, make material from large to small, gradually whereabouts until discharge through the discharge port.

Jaw Crusher Maintenance

Jaw crusher problems that may arise during the operation

  • 1. Jaw crusher mainframe sudden shutdown (commonly known as: nausea car).
  • 2. Jaw crusher factory production why not up the standard?
  • 3. Why jump or crash when the movable jaw crusher and fixed jaw work?
  • 4. Jaw crusher mainframe sheaves, moving jaw functioning normally, but broken cease work?

How to solve the jaw crusher problems during operation?

Jaw crusher factory production why not up the standard?

  • 1. Replace or increase the crusher;
  • 2. Exchange the electrical wiring;
  • 3. The discharge opening adjusted to the provisions of the nominal discharge opening and increasing crusher for crushing;
  • 4. Check teeth pitch dimensions, such as sub-standard replacement jaw plate, adjusting the relative position of the fixed jaw plate and movable jaw plate, ensuring the top of the tooth root, the fixed clamping to prevent displacement;
  • 5. Increase the voltage of the workplace to adapt host overload requires;
  • 6. Replace the bearings or moving the jaw.

Why the beating sound when jaw crusher jaws work?

  • 1. True or bolts tight;
  • 2. Align the discharge opening, ensure the correct gap between the two jaw plates.

The host sheaves, moving jaw functioning normally, but the work stopped?

  • 1. Replace the tension spring;
  • 2. Replace the rod;
  • 3. Re-install or replace the bracket.
