Large jaw crusher: ideal for efficient crushing

Large jaw crushers are suitable for large-scale production, high efficiency and energy saving, strong processing capacity, and can crush a variety of materials. The integrated design is easy to install and adjust, and high-quality casting and forging ensures stable and efficient equipment. Mass production is achieved through the curved extrusion working principle.

Compared with small jaw crushers, large jaw crushers have larger specifications, larger volumes, and higher outputs, and are particularly suitable for large-scale manufacturers. Its high output and high efficiency make it widely used in construction, water conservancy, railways, highways, power plants, bridges and other fields. Whether it is river pebbles, granite, marble, or limestone, iron ore, coal gangue, steel slag, slag and other materials, large jaw crushers can provide excellent crushing effects.

Features and advantages of large jaw crushers

1. Large specifications and high output Large jaw crushers can produce up to 1300-2200 tons per hour, with a maximum feed size of 1500mm, which can handle large-scale crushing needs. For example, the maximum feed of PE-1500×1800 large jaw crusher is 1200mm, the processing capacity can reach 500-1000 tons per hour, and the size of the discharge port is between 220-350mm.

2. High-efficiency and energy-saving large jaw crusher has the characteristics of energy saving and green environmental protection, easy operation, reliable quality, stable operation, and has been widely recognized and loved by users. Whether it is coarse crushing or fine crushing, it can do it to ensure production efficiency.

3. Multiple specifications are available Large jaw crusher has a variety of specifications to choose from. The following are common models and their parameters:

PE-1200×1500: feed particle size 1020mm, discharge port adjustment range 150-350mm, total weight 100.9t, eccentric shaft speed 180r/min, motor power 160-220kw, processing capacity 400-800t/h.

PE-1500×1800: feed size 1200mm, discharge opening adjustment range 220-350mm, total weight 122t, eccentric shaft speed 180r/min, motor power 280-355kw, processing capacity 500-1000t/h.

PE-1600×2100: feed size 1500mm, discharge opening adjustment range 300-400mm, total weight 150.6t, eccentric shaft speed 160r/min, motor power 350-3800kw, processing capacity 1300-2200t/h.

Core technology and advantages of crusher

1. Quick installation and convenient production The new jaw crusher adopts an integrated motor seat design. The motor seat is directly fixed on the crusher. There is no need to make a motor foundation. While reducing the installation space, the power transmission is more stable, which is convenient for rapid production.

2. Convenient adjustment operation The crushing chamber is deep and has no dead zone. The double wedge is used to adjust the discharge port. It can be adjusted mechanically or hydraulically as needed. It is simpler and more efficient than the traditional pad-type discharge port adjustment operation, and the crushing efficiency is higher.

3. High-quality casting and forging ensures the reliability of the equipment. The core rotating parts adopt high-quality casting movable jaw body, large eccentricity heavy forged eccentric shaft, high moment of inertia casting flywheel and high-strength integral cast steel bearing box to ensure stable and efficient production of the equipment.

Working principle

The large jaw crusher works in a cam extrusion type. The motor drives the belt and pulley to move the movable jaw up and down through the eccentric shaft. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, pushing the movable jaw plate to approach the fixed jaw plate, and the material is crushed or split. When the movable jaw descends, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw plate leaves the fixed jaw plate under the action of the pull rod and spring. The crushed material is discharged from the lower opening of the crushing chamber. As the motor rotates continuously, the movable jaw of the crusher performs periodic motion to achieve mass production.
