MJ Series Jaw Crusher

MJ series jaw crusher is mainly used as coarse crusher. It is made of advanced technology in Europe and America and high-quality wear-resistant raw materials. The equipment has good performance, large crushing ratio and high output. It mainly deals with high strength and high hardness materials. It is the primary equipment of mine crushing production line and lays a good foundation for subsequent equipment. The design of this new type of jawbone structure is more scientific and reasonable, and the operation parameters, structural form, maintenance and adjustment of the equipment have more advantages than traditional machines.

Technical Advantages

  1. High crushing efficiency in deep cavity
    The crushing cavity of MJ European jaw crusher adopts symmetrical V-shaped structure, and the discharge port adopts wedge adjustment device, which makes the adjustment easier, safer and faster.
  2. The bearing capacity of the equipment is strong
    The equipment adopts larger and more durable eccentric shaft bearing and tooth guard plate, which makes the equipment have stronger bearing capacity, higher output and longer service life.
  3. Advanced manufacturing technology
    For the manufacturing of European jaw crusher, not only high-end materials are selected, but also the technology is more advanced. The movable jaw assembly is made of high-quality steel castings, and the heavy eccentric shaft is processed by forging blank, which is more reliable and durable.
  4. More convenient adjustment of discharge
    New wedge adjustment design, more uniform discharge, discharge port adjustment operation is more simple and safe, discharge size adjustment range is large.
  5. Unit integration structure
    The whole machine can be placed on the base of the steel frame. The main machine and the base can be linked through the damping pad, so the noise is small.
  6. Steel plate elbow plate
    The elbow plate is made of high-strength steel plate, which can bend and deform when the crusher is overloaded to protect the key parts of the crusher from damage. Compared with the traditional cast iron elbow plate, it has the advantages of light weight, easy replacement, and avoiding the broken cast iron elbow plate and damaging the crusher.

Working Principle

When MJ series jaw crusher works, the motor drives the belt and pulley to make the moving jaw move up and down through the eccentric shaft. When the moving jaw rises, the angle between the elbow plate and the moving jaw becomes larger, so as to push the moving jaw plate close to the fixed jaw plate, and at the same time, the material is crushed or split to achieve the purpose of crushing; When the movable jaw goes down, the angle between the elbow plate and the movable jaw becomes smaller, and the movable jaw plate leaves the fixed jaw plate under the action of the pull rod and the spring. At this time, the crushed materials are discharged from the lower opening of the crushing cavity.
