Large jaw crusher can be said to be indispensable to the mining crushing industry, whether it is crushing production line, sand production line, or grinding production line, mineral processing production line, can not be separated from it. Large jaw crusher appeared earlier, the feed port is large, soft and hard, suitable for a wide range of materials, whether it is performance, market or price are very mature, this article for everyone to explain the working principle of jaw crusher.
1, large jaw crusher working principle
The large jaw crusher is used for coarse and fine crushing of various ores and rocks with compressive strength of 147-245MPa. The working mode is curved extrusion type, the motor drives the belt and pulley, and the moving jaw moves up and down through the eccentric shaft to achieve the purpose of crushing the material, and the broken material is discharged from the lower mouth of the crushing chamber. With the continuous rotation of the motor, the crusher jaw makes periodic movement to crush and discharge materials to achieve mass production.
2, large jaw crusher performance characteristics
A. The structure is reasonable, the parts wear resistance adopts the crushing process, so that the internal structure of the equipment is more precise, and the components are made of wear-resistant and pressure-resistant materials, which enhances the pressure resistance and wear resistance of the parts. The moving jaw is made of high quality cast steel parts and the eccentric shaft is made of forged billet, which improves the wear resistance and working reliability of the parts.
b, deep cavity crushing, energy saving and high yield
Large jaw crusher deep "V" type crushing chamber, improve the feeding capacity and output, the material in the crushing chamber will not occur plugging phenomenon, crushing ratio, uniform product particle size, single energy saving effect is good.
c, simple operation, easy maintenance
Large jaw crusher is equipped with wedge discharge port adjustment device, discharge port adjustment is simpler, safer and faster. On the other hand, the machine uses a specially designed centralized lubrication system, parts lubrication is simple and fast, and daily maintenance is convenient.
d, high equipment strength, good bearing capacity
Using finite element analysis technology, the crusher has higher strength, and is equipped with eccentric shaft bearings that are more durable than other crushers of the same specifications, and the bearing capacity and sealing effect are improved.
