PEW Jaw Crusher

PEW jaw crusher (European version of the jaw crusher) best suited to crushing compression strength not more than 280Mpa ore, rock, slag, etc., the largest block of the material to be broken is not greater than the technical parameters specified in the table.

It is mainly used in metallurgy, mining, chemical, cement, construction, refractory and ceramics and other industrial sectors for secondary and tertiary crushing of various medium-hard ores and rocks. Today, Shanghai SBM PEW series jaw crusher has become the undisputed world's most popular jaw crusher. When considering efficiently hard, strong abrasive materials crushing, we should first choose to use the most advanced international crushing technology and manufacturing level PEW Series European version of the jaw crusher.

Features Of PEW Jaw Crusher

  • 1. using the world-class manufacturing processes, selection of the most high-end production of materials.
  • 2. More advanced movable jaw assembly to make it more durable. Movable jaw assembly adopts high-quality cast steel structure, and through two large cast steel flywheel drive. Further heavy eccentric shaft has also adopted forging billet for processing, which were all so PEW series jaw crusher with exceptional reliability.
  • 3. using integrated steel bearing structure. Overall steel bearing frame to ensure full cooperation with the broken, but also greatly enhance the radial strength of the bearing seat, and split bearing not have this advantage.
  • 4. the use of finite element analysis technology, the crusher has a higher strength.
  • 5. the crushing cavity symmetrical "V" shaped configuration so that the actual width of the nominal inlet width of the inlet consistent.
  • 6. the discharge opening to adjust more quickly and conveniently. European version of the PEW series jaw crusher discharge port is equipped with wedge adjustment device which is simpler than shimming, safer and faster.
  • 7. selection of bearing size larger, higher carrying capacity. All PEW series jaw crusher are equipped with the same specifications than other crushers greater and more durable eccentric shaft bearings, the higher carrying capacity and effective labyrinth seal greatly extend the service life of the bearing.

Working Principle Of PEW Jaw Crusher

In the huge stones broken into small stones in the process, the first crusher is usually referred to as "master" crusher. When the jaw crusher to feed the material from the top of the entrance into the crushing chamber containing the jaw teeth. E tooth with great force to the top of the wall material, it will be crushed into smaller stones. Support E tooth movement is an eccentric shaft, the shaft through the body architecture. Eccentric motion is usually fixed at both ends of the flywheel axle generated. Flywheel and eccentric support bearings are often used spherical roller bearings, the working environment is very harsh. Bearings must withstand tremendous impact loads, abrasive sewage and high temperatures. Although this work environment is extremely harsh, jaw crusher still need to work very reliably, which is to ensure the productivity of a key ring.

PEW European version of Jaw Crusher is curved dynamic compression type. Its working principle is: motor-driven belt and pulley, through the eccentric shaft to move back and forth up and down the jaw, when the movable jaw to the fixed jaw plate movable pushing jaw movement, the material is crushed or split pieces. When the effect of movable jaw plate and movable jaw eccentric shaft, spring back under previously been crushed or split pieces of material from the lower jaw of the discharge port discharge. With the continuous rotation of motor broken motor jaw periodically crushed and fecal material, to achieve mass production.
