Jaw type comprehensive crusher

Jaw type comprehensive crusher is a widely used crushing equipment in many fields such as mining, metallurgy, building materials, highways, railways, water conservancy, and chemical industry. The following is a detailed introduction to the jaw type comprehensive crusher:

1. Working principle

The working principle of the jaw type comprehensive crusher mainly simulates the movement of the two jaws of animals to complete the crushing operation. When the movable jaw rises, the angle between the elbow plate and the movable jaw increases, thereby pushing the movable jaw plate closer to the fixed jaw plate. At the same time, the material is subjected to multiple crushing processes such as compression, rubbing, and grinding; When the moving jaw descends, the angle between the elbow plate and the moving jaw decreases, and the moving jaw plate separates from the fixed jaw plate under the action of the pull rod and spring. At this time, the crushed material is discharged from the lower mouth of the crushing chamber, and as the electric motor continues to rotate, the moving jaw of the crusher performs periodic crushing and discharging, achieving mass production.

2. Structural characteristics

1. Rack: Made of integral cast steel or high-quality carbon steel plate welded together, it has sufficient strength and rigidity to support eccentric shafts, bearing seats, flywheels and other components.
2. Eccentric shaft: Made of high-quality alloy steel forging, it has undergone quenching and surface treatment, and has high strength and wear resistance.
3. Jaw plate: Made of high manganese steel or wear-resistant alloy steel, it has good wear resistance and impact resistance.
4. Adjustment device: used to adjust the size of the discharge port to meet products with different particle size requirements. Common adjustment methods include gasket adjustment, wedge adjustment, and hydraulic adjustment.
5. Transmission device: composed of an electric motor, a V-belt, a flywheel, bearings, etc., used to transmit power and drive the moving jaw for crushing operations.
In summary, jaw type comprehensive crusher is an efficient and reliable crushing equipment that plays an important role in mining, metallurgy, building materials and other fields. When making a purchase, one should fully understand their own needs, choose manufacturers with strength and reputation for cooperation, and ensure the quality and after-sales service of the equipment.
