Up till now, the annual production of China’s brittle materials has reached as much as 1.5 billion ton and most of these materials need to be crushed and ground, so the jaw crusher manufacturing is confronted with urgent development and optimization situation.

Jaw crushers are made of steel materials, so to select good quality steel is very important. Wear resistance is the core concern for steels and the main wearing parts of the jaw crusher are jaw board and guard board. The jaw board is made of high quality high manganese steel alloy and we can adjust carbon steel proportion during the casting process to improve the hardness and resistance of the materials.
When talking about the optimization of structures of jaw crushers, we mean the optimization of the entire machine appearance, component appearance and assembly unit. The main case of the jaw crusher can be cast and welded or be connected by the bolt, so that the adaptability of jaw crushers in the field have been greatly improved. The cavity shape can be optimized to change the fracture surface of the toothed plate and to gain more reasonable crushing cavity curve.
The jaw crusher is called the leading crusher among so many crushing machines, so once the daily maintenance and preservation don’t catch up, the jaw crusher will suffer serious abrasion and service life shortening. Nowadays the jaw crusher has been armed with circular lubricant passage way and cooling system, which will definitely reduce both the equipment wear and the maintenance cost.
