PEW Series Jaw Crusher

PEW jaw crusher machine PEW series jaw crusher is the world's most popular jaw crusher, suitable for secondary and tertiary crushing compression strength not higher than 280MPa ores and rocks, especially suitable for hard and strong corrosive material, used in metallurgy, mining, chemical, cement, construction, refractory and ceramic industries.

The series of jaw crusher has large crushing ratio, even granularity, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics.

Features

  1. Width of actual feed port is consistent with the one of nominal feed port which is able to meet a big feeding.
  2. Wedge-shaped hydraulic adjustment which is adopted features simple structure and easy fabrication and enable to realize automatic control and stepless adjustment.
  3. The swing jaw through mechanically optimization is a suifficient condition for ensuring the superior performance of the crusher. The PEW series SBM is composed of high quality cast steels. Heavy eccentric shaft is processed by forging stock which will lightens the weight of swing jaw meanwhile its stiffness and strength will also be improved.
  4. It makes more convenient lubrication for the bearings and more stable operation for the machine.
  5. It ensures the perfect fitting with the crusher rack which has greatly strengthened the radial strength of the bearing block.
  6. It has strengthened the finite element optimal design of the rack and swing jaw which helps to reach both light weight and high reliability.

Working Principle

PEW jaw crusher machinePEW series jaw crusher mainly consists of frame parts, eccentric shaft portion, crushing working part chamber, safety device, nesting population adjustment device and other components.

PEW series jaw crusher is song moving extrusion type. Motor drove belt and pulley, through the eccentric shaft to move the jaw back and forth up and down, when the movable jaw to the fixed jaw plate movable pushing jaw movement, the material is crushed or split pieces. When the effect of the movable jaw and the movable jaw plate in the eccentric shaft, spring back, the previously been crushed or split pieces of material from the lower jaw of the discharge port discharge. With the motor continuously rotating and mobile jaw crusher for cyclically crushing and waste material, to achieve mass production.
