The complex oscillating jaw crusher structure and overload protection system, jaw crusher is the oldest crusher, but because of its simple structure, safe and reliable work, large range of objects, it is suitable for crushing hard materials, so the crusher is widely used in industrial and mining enterprises such as metallurgy, coal, chemical industry, building materials, etc. It is also the most widely used in cement plants, but its crushing ratio is small, the particle size of the crushed material is not uniform, it is intermittent work.
There is a idling process, but it is a good method for coarse and medium crushing of materials, so it is still widely used in industrial and mining enterprises. However, with the development of society, people need to improve the machine in order to reduce the cost and increase the life of the machine. Therefore, increasing the overload protection system is also a method to extend the life of the machine. Jaw crusher is one of the main equipments for mine production, construction material processing and polymerization chemical production.
It is widely used in the production and processing of various metal and non-metal mines, chemical minerals, cement and building materials. In recent years, with the introduction of some new theories in mine production and building materials processing, users hope that the bulk ore can obtain as fine a product with finer grain size and better blockage as possible in the crushing stage, as well as production automation and reduce labor costs.
