PEW Jaw crusher

pew jaw crusher

PEW Jaw crusher Widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry in a variety of ores and bulk materials of medium-grained broken. Maximum compressive strength of the material to be broken for 320Mpa.The most important is SBM is profession in PEW jaw crusher.if you want to know more about PEW jaw crusher,click here.Service Online >

PEW Jaw crusher Jaw crusher structure

Eccentric shaft assembly: The main part has a flywheel, pulley, eccentric shaft, moving jaw, movable jaw plate, movable jaw wedge, bearings, bushings, shaft baffles, dust ring, oil seal.

Adjusting device include: the thrust plate, thrust plate seat, hanging spring, damper, screw, lock nut and adjust the handle.

Body and accessories include: body, hopper, fixed jaw plate, fixed jaw wedge, liner, bearing caps, motor pulley, motor track and so on.

PEW Jaw crusher Works

Power machine of power through the belt drive slow down and drive the eccentric shaft rotates, the eccentric shaft is rotated horizontally movable jaw forced to move up and down motion, thereby ore jaw crusher cavity through the discharge port discharge, close to the lower end of the movable jaw thrust plate by nut and screw to adjust the discharge opening width to accommodate post-discharge needs of different size, or to compensate for the wear, nesting population adjustment, tighten the lock nut must take, you can turn around and use the rear end of the jaw wear the other end.

Movable jaw assembly with two rolling and the eccentric shaft radial ball bearing, the eccentric shaft in the body by means of two aligning rolling bearing.

When motors are used, the machine is equipped with a motor, magnetic starters and control buttons. Depending on the choice of power overload protection device depending on the machine, if selected motors, magnetic starter relay thermal control within its operating current. If the election of the other power machine for power, breaking through the thrust plate to protect the machine from damage important parts.

How to Select the PEW jaw crusher jaw plate

PEW jaw crusher working chamber by moving jaw and fixed jaw constitute the composition is a major jaw jaw crusher wear parts: the movable jaw plate, static jaw, jaw crusher, depending on the model, there are a variety of model size, PEW jaw crusher adopts new high manganese steel casting, in order to increase its durability.

PEW jaw crusher Moving jaw and fixed jaw broken under tremendous force and friction materials, easily worn, in order to protect the jaw, generally moving jaw and fixed jaw surface mount wear liner, this liner is also known as broken plate . When the jaw broken machine work, broken down into two parts wear plate is not the same speed, the lower wear out faster than the upper, broken plate when the jaw crusher work, direct contact with the material, under enormous crushing force and materials friction, broken plates life is directly related to the efficiency and cost of production PEW jaw crusher, jaw when choosing carefully.

  • the choice of manganese alloys, high degree of wear and long life.
  • the use of cold-hardening technology, high hardness.
  • water and tough treatment, avoiding the use of naturally occurring phase change leaving poor performance.
  • the factory must undergo strict quality control, choose the strength of maternity leave, the quality is guaranteed.

PEW jaw crusher Jaw is vulnerable parts of jaw crusher, in the course of repair and maintenance on a regular basis, in addition to the production process, materials and jaw direct force is high, particularly when broken greater hardness materials, resulting in installing bolts vibrating jaw, nut loose, so jaw wear and tear and have a great noise, severe jaw broken off or make equipment downtime, affecting the normal production. Jaw when failure must be timely repair and replacement, to avoid affecting productivity.
