Technical features of PEW jaw crusher

PEW jaw crusher that our company produce is a highly efficient, energy-saving crushing equipment. Jaw crusher machine is basically necessary in stone crushing production line, because under normal circumstances these materials will be relatively large, the feed requirements of the secondary equipment is relatively small. Therefore, the jaw crusher machine is particularly significant importance in stone production line, sand production line being, mineral production line and milling equipment.

Advantages of PEW jaw crusher

1.crushing chamber is deep and has no dead zone, which can improve the ability to feed and production.

2.Gasketed nesting population adjustment device make jaw crusher machine reliable and convenient and also has a large range of adjustment which can increase the flexibility of the device.

3.The lubrication system is safe and reliable.parts are easy to replace.Its maintenance workload is small.

4.The nesting population has a large range of adjustment which can meet different user requirements.

5.Compared with other crusher machines,PEW jaw crusher has a lower noise and less dust.

Brief introduction

It can be well-known and taken for granted that the efficiency of power use by comminution (i.e. breaking, crushing, grinding) gear is quite low, commonly much less than 10%. Many of the process input power is dissipated as heat and noise and ineffective deformation from the material to be processed as well as the device itself. Here, a study is reported that analyses the reasons for this low efficiency and tries to offer recommendations for improvement. With a lab-scale jaw crusher as a test case, an optimisation was created on tips on how to operate it most energy-efficiently by using an evolutionary algorithm numerical technique. For a selected optimised case an attempt was produced to simulate the jaw crusher utilizing a industrial software for discrete element modelling (DEM), soon after initial simulating single particle breakage utilizing this software program. Also, some experimental outcomes on the crushing of a number of ??600 g pieces of rock though measuring electric energy during the method are reported.
