PEW Jaw Crusher

The motor of PEW jaw crusher drives belt and pulley, through the eccentric shaft to move the jaw up and down. When moving jaw pushes movable jaw plate to the fixed jaw plate movement, the material is crushed or split pieces. When the effect of moving jaw and movable jaw plate in the eccentric shaft, spring back, the previously crushed or split material will discharge from the lower jaw of the discharge port. With the motor continuously rotates and moving jaw of crusher for crush and row unloading of materials periodicly, to achieve mass production.

The Reasons And Solution Of Jaw Plate Abrasion In Jaw Crusher

Jaw crusher is widely used in mining, metallurgy, construction and other industries. Its working body is a typical crank rocker. Jaw crusher works very simple. However, jaw plate which is the wearing parts of jaw crusher is a wear piece. For the crushing ratio and the continuous operation of the plant, reducing the wear of the jaw plate and prolonging the service life of the machine restricts whether the factory can do continuous production. So GBM come to tell you the reasons and solution of jaw plate abrasion in jaw crusher:

The reasons of jaw plate abrasion:

  • 1, Jaw plate and machine surface contact is not smooth;
  • 2, The eccentric shaft speed is too fast, the material has been broken too late, resulting in broken cavity plug, jaw plate wear;
  • 3, The material properties changed, but the crusher did not make timely adjustments;
  • 4. The angle between the active jaw plate and the fixed jaw plate is too large, and exceed the normal range;
  • 5, Jaw plate of its own strength, wear resistance and the fight against bad performance.

The solution of jaw plate abrasion in jaw crusher is:

  • 1, In the installation of jaw plate, GBM requires it must be installed and fixed tightly, making the surface stationary in contact with the machine;
  • 2, Putting a layer of plastic between the jaw plate and the machine surface;
  • 3, Carry on the sampling of material that each batch into the crusher. Once find that the properties of the materials have relatively large changes, staff should change the crusher parameters in time, which matched with the incoming materials;
  • 4, Jaw plate must choose the high hardness, wear-resisting, the fight strong material;
  • 5, With ore crushing production line process, cement enterprises can interchangeable the jaw plates used in coarse crushing mines and cement fine with wear. We can repair worn jaw plate by surfacing welding method.

The advangtage of our products

  • 1. Good stability and high reliability:

    the movable jaw of PEW jaw crusher assembly adopts high-quality cast steel structure. Heavy eccentric shaft also adopts forging billet for processing. It all makes jaw crusher with exceptional stability. Compared with the same specifications crusher, we use larger and more durable eccentric shaft bearings, making it higher carrying capacity to ensure its reliability.

  • 2. Advanced technology and long life:

    PEW jaw crusher uses world-class manufacturing processes, and uses advanced digital processing equipment, ensuring precision of machine parts. The selection of the most high-end production of materials, enhances its compressive strength, abrasion resistance and greatly extends life of the machine.

  • 3. Simple structure and easy maintenance:

    Through continuous improvement to optimize, improving the performance of the machine at the same time ensure the machine structure is simplified. Entire machine becomes easier to operate, more convenient maintenance and downtime maintenance time is greatly shortened.

  • 4. Large Grain production well:

    The use of advanced crushing principle, makes the proportion of the cube of the product significantly increases, flake stone needles reduces and the grain size more uniform.
