Performance
1.Stable Structure, Reliable Performance.Integral cast steel structure is adopted for bearing seat, this technology not only guarantees the perfect fitting and seamless connection of crusher rack, but also enhances the radial strengths of the parts, thus realizing more reliable performance and higher durability of the jaw crusher.
2.Hydraulic Control, Convenient Cavity Clearing.PEW Jaw Crusher is equipped with the hydraulic oil station to ensure that the lubrication system supplies oil to the lubrication components, providing security for the safe operation of the machine. At the same time, if the crusher shuts down with load, the hydraulic clearing system can quickly clean the crushing chamber, greatly reducing downtime.
3.V-type Crushing Chamber, Toothed Guard Board.PEW Jaw Crusher has more reasonable "V" crushing chamber and toothed guard board. By them, the actual size of feeding materials can be consistent with ideal size, which can effectively enlarge the crushing space. Besides, materials wouldn’t pile in the crushing chamber, so the crushing ratio and capacity can reach the optimal status and the utilization of jaw plates could extend.
4.Wedge Device, Convenient Adjustments.PEW Jaw Crusher adopts a wedge discharging adjustment device, so that the machine can turn the discharge port to a preset value within minutes even under the idling circumstance. In cooperation with the hydraulic system, automation is available. Compared with the old gasket discharging adjustment device, this device is simpler, safer and quicker.
Working Principle
The motor of PEW Jaw Crusher drives belt and pulley to make the movable jaw move back and forth, up and down around the eccentric shaft. When the movable jaw pushes the movable jaw plate to the fixed jaw plate, materials are crushed or chopped. When the movable jaw and plate retreats under the function of the eccentric shaft and spring, materials which previously have been crushed are discharged from the lower part of the jaw plate. With the continuous rotation of the motor, the movable jaw can periodically crush and discharge materials to achieve mass production.
