The working mode of the jaw crusher is a curved extrusion type. The working principle is: the motor drives the belt and the pulley, and the moving shaft moves up and down through the eccentric shaft. When the moving jaw rises, the angle between the bracket and the moving jaw becomes larger, thereby Pushing the moving jaw to approach the fixed jaw, at the same time the material is crushed or crushed to achieve the purpose of crushing; when the moving down, the angle between the bracket and the moving jaw becomes smaller, the moving jaw is in the tie rod, and the spring acts Next, leave the fixed jaw, and the broken material is discharged from the lower opening of the crushing chamber. As the motor rotates continuously, the crushing maneuvering cycle motion crushes and excretes the material to achieve mass production.
Jaw crusher use and scope of use
1. This series of crushers are mainly used in the industrial sectors such as metallurgy, mining, chemical, cement, construction, refractory materials and ceramics for medium and fine crushing of various medium hard ores and rocks.
2. This series of crushers is most suitable for crushing various soft and hard ores with compressive strength not higher than 300MPa (MPa). The maximum block size of the crushed materials shall not exceed the technical parameters.
Jaw crusher operating environment:
In the process of breaking huge stones into small stones, the first crusher is often referred to as the "main" crusher. The longest and most sturdy crusher is the jaw crusher. When feeding the jaw crusher, the material is poured from the top inlet into the crushing chamber containing the teeth. E-tooth pushes the material to the chamber wall with great force, breaking it into smaller stones. Supporting the movement of the teeth is an eccentric shaft that runs through the fuselage frame. Eccentric motion is usually produced by a flywheel that is fixed at both ends of the shaft. Flywheels and eccentrically supported bearings often use spherical roller bearings, and the working environment of the bearings is extremely demanding. Bearings must withstand large shock loads, abrasive sewage and high temperatures. Despite the extremely harsh working environment, the jaw crusher still needs to work very reliably, which is a key part of ensuring production efficiency.
