Jaw crusher advantage in crushing equipment

Jaw crusher working principle: motor drive belts and pulleys, through the eccentric shaft to move up and down the moving jaw, when the dynamic jaw rises, the angle between the elbow and the movable jaw becomes larger, so as to push the jaw plate close to the fixed jaw, and At the same time, the materials are crushed or smashed to achieve the purpose of crushing; when the jaws descend, the included angle between the bracket and the jaw becomes smaller, and the jaws move away from the fixed jaw under the action of the tension bar and the spring. The broken material is discharged from the bottom of the crushing chamber. As the motor continuously rotates and breaks down, it periodically crushes and excretes materials, achieving mass production.

Jaw crusher appeared in 1858. Although it is an ancient crushing equipment, it is still in metallurgical mines, building materials, chemical industry and railways due to its simple structure, reliable work, easy manufacture, and easy maintenance. Other departments are widely used. In mines, it is mostly used for coarse and medium breaking of hard or medium hard ore.

Jaw crusher performance advantages in the following aspects:

1. The crushing cavity is deep and has no dead zone, which improves the feeding capacity and output; the crushing ratio is large and the product particle size is uniform;

2. Gasket-type discharge port adjustment device, reliable and convenient, large adjustment range, increase the flexibility of the equipment;

3. Lubrication system is safe and reliable, parts are easy to replace, maintenance work is small; the structure is simple, work is reliable, and operating costs are low.

4.Equipment energy-saving: Single-machine energy-saving 15% to 30%, the system energy-saving more than double; discharge mouth adjustment range, can meet the requirements of different users; low noise, less dust.

Jaw crusher adopts hydraulic safety device, which is reliable and safe, and easy to troubleshoot. Large and medium-sized crushers generally use babbitt cast plain bearings, which can withstand large impact loads and are relatively wear-resistant. The small jaw crusher has many rolling bearings. It has high transmission efficiency and easy maintenance.
