Jaw Crusher

The jaw crusher squeezes rock between two surfaces, one of which opens and closes like a jaw. Rock enters the jaw crusher from the top. Pieces of rock that are larger than the opening at the bottom of the jaw lodge between the two metal plates of the jaw. The opening and closing action of the movable jaw against the fixed jaw continues to reduce the size of lodged pieces of rock until the pieces are small enough to fall through the opening at the bottom of the jaw. It has a very powerful motion.

Features / Advantages:

  • Simple structure, easy maintenance
  • Flexible capacity
  • Stable performance
  • Over loading protection
  • High efficiency and low operation cost
  • Even final particles and high crushing ratio

Jaw Crusher Application

For mineral mining processing, jaw crusher can be used for the crushing processing of bauxite, copper ore, gold ore, iron ore, lead ore, manganese, silver ore, zinc ore , alunite, aragonite, arsenic, asphalt , ball clay, barytes, basalt, bentonite, coke, concrete , dolomite, feldspar, granite, gravel, gypsum, kaolin, limestone, marble, quartz, silica sand , etc. Often used as primary crushing processing equipment, jaw crusher is easy maintenance and well for installation.

Jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even. They are widely applied to crush high hardness, mid hardness and soft rocks and ores such as slags, construction materials, marble, etc. The pressure resistance strength is under 350Mpa, that is, suitable for primary crush. Jaw Crusher can be used in mining, metallurgical industry, construction, road and railway building, conversancy, chemistry, etc.

Jaw Crusher Structure & Wear Parts

  • The structure of jaw crusher contains the frame, eccentric shaft, big belt pulley, flywheel, movable jaw, side guard plate, toggle plate, rear seat of toggle plate, modulation gap screw, returning spring, fixed jaw plate and movable jaw plate, etc, among which the toggle plate is used for safety. The working mode of this series jaw crusher is pressing deviously.

Working Principle of Jaw Crusher

This crushing machine working theory is: The motor drives belt and belt wheel, the eccentric shaft causes the movable jaw to move down and up, forward and backward, the angle between toggle plate and movable jaw becomes bigger when the movable jaw moves up, so that the movable jaw moves toward the fixed jaw, and the materials are pressed, crushed, or cut, as a result, the aim of crushing is accomplished.

The angle between toggle plate and movable jaw becomes smaller when the movable jaw moves down, the movable jaw leaves the fixed jaw because of the function of drag link and spring, here the crushed materials are discharged from the bottom hole of crushing chamber. Along with the continuous turning of motor, the movable jaw of crusher moves periodically to crush and discharge materials, so that the mass production is obtained.
