PEW Jaw Crusher

PEW Series

Input Size: 0-930mm

Capacity: 12-650TPH

Material: Granite, marble, basalt, limestone, quartz, pebble, copper ore, iron ore

Stable Structure, Reliable Performance

SBM uses high-quality steel castings for core load bearing parts of jaw crusher, i.e. moving jaw and bearing block; 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.

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.

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.

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.

Digitalized Processing, Higher Precision

There are tens of lines of numerical controlling machine tools. Operations such as steel plates’ cutting, bending, planing, milling and paint spraying are all controlled numerically. The machining precision is high, especially for the core parts.

Sufficient Supply of Spare Parts, Worry-free Operation

SBM, whose businesses cover production and sales, takes responsibility for every machine produced by ourselves. We can offer customers technical services about products and original spare parts to ensure the worry-free operation.

Working Principle

Firstly, the motor 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 towards the fixed jaw plate, materials get crushed. When movable jaw and plate move backwards under the action of the eccentric shaft and spring, the materials crushed before would be discharged from the port under the jaw plate. As the motor works continuously, the movable jaw can crush or discharge materials periodically, so that volume production can be achieved.

APPLICATION

Jaw Crusher - Installation

The jaw crusher is a large crusher installed and receives no-load testing in the manufacturer's workshop. However it is disassembled into components for transport.

Jaw crusher - Lubrication

To ensure normal operation and extend service life of the crusher, regular lubrication shall be performed. Grease in the bearing block shall be replaced every 3 to 6 months.

Jaw Crusher - Troubleshooting

Movable jaw does not rotate while flywheel is rotating . Crushing plate shakes and makes collision noise

Crushing Production Line - Installation

Set markings for placement thickness control, for example, horizontal standard piles or elevation piles.
