The PEW Heavy-Duty Jaw Crusher is most suitable for crushing ores, rocks, slag, etc., with a compressive strength of no more than 280 Pa. The maximum lump size of the material to be crushed must not exceed the limits specified in the technical parameter table. The PEW Jaw Crusher is highly trusted by customers who pursue high-quality equipment due to its superior performance and stable, reliable quality, making it a preferred choice among many high-efficiency crushing machines.
Application Field
Used for intermediate and fine crushing of various medium-hard ores and rocks in industrial sectors such as metallurgy, mining, chemical industry, cement, construction, refractory materials, and ceramics.
Applicable Materials
Limestone, granite, marble, basalt, iron ore, river stone, shale, bluestone, coal, pebbles, construction waste.
The Heavy-Duty Jaw Crusher is mainly composed of the frame assembly, eccentric shaft rotation assembly, crushing chamber working assembly, safety device, and discharge opening adjustment device.
- Frame Assembly: Composed of side plates, front box assembly, and rear box weldment.
- Eccentric Shaft Rotation Assembly: Mainly composed of the movable jaw, eccentric shaft, bearings, bearing seats, and pulley. This is the main part for transmitting power.
- Crushing Chamber Working Assembly: Mainly composed of the fixed jaw plate, movable jaw plate, side liner plates, and guard plates. These are the working parts for crushing materials.
Working Principle
The motor drives the belt and pulley, which causes the eccentric shaft to make the movable jaw swing back and forth, up and down. When the movable jaw pushes the movable jaw plate towards the fixed jaw plate, the material is crushed or split. When the movable jaw and movable jaw plate retreat under the action of the eccentric shaft and springs, the previously crushed or split material is discharged from the lower opening of the jaw plates. With the continuous rotation of the motor, the movable jaw of the crusher periodically crushes and discharges the material, achieving batch production.
Product Advantages
- High Capacity: Adopts a deep cavity V-shaped structure, allowing for a larger feed size (compared to ordinary jaw crushers) and higher output.
- Enhanced Safety and Longevity: Better guarantees safety and greatly increases the load-bearing capacity of the jaw head, making the machine more efficient and safe, and extending the life of the bearings and main shaft.
- Convenient Adjustment: Features a brand-new adjustment structure for the discharge opening, making it convenient, fast, and safe. The structure is compact and uniquely designed.
- Simplified Maintenance: New oil circuit design, used in conjunction with an oil pump, simplifies operation and maintenance and enhances efficiency.
