It is mostly used for hard or medium hard ore for coarse and broken in mining.
 
The crushing chamber of jaw crusher is deep without dead zone, thus improving the feed capacity and yield. And its big crushing ratio, uniform product size; chip discharge port adjustment device, which is reliable and convenient. The large adjustment range, increasing the flexibility of the equipment. Lubrication system is safe and reliable, easy parts replacement, so maintenance workload is small, simple structure is reliable, low operating costs. Equipment energy saving: 15% to 30% energy saving machine, the system energy saving more than double; a wide adjustment range of discharge port, to meet the requirements of different users.
The machine uses hydraulic safety device, that is reliable and easy to remove the fault. Large and medium-sized crusher are generally cast with Pasteur's plain bearings, it can withstand greater impact load, and more wear-resistant.Small jaw crusher with multi-purpose rolling bearings, its high transmission efficiency, easy maintenance.

Jaw crusher is widely used in metallurgy, chemical industry, in which jaw crusher with good performance, high productivity, so in the small and medium series crusher occupy a large proportion, and continue to a large-scale development trend.

But the machine vibration, weight and friction and other issues are still more prominent. High energy consumption, reasonable choice of working parameters and design of its structural parameters, is conducive to energy conservation.
