Cone crusher is the main crusher used in secondary crushing process. In the past, cone crusher are mostly applied in mineral processing, especially for iron ore, gold and other kinds of ore crushing of the powerhouse. Now for the development of cone crusher, crushing sand and gravel equipment to shuffle.Because of cone crusher low energy consumption, high output, so is the national advocate of gravel equipment, the application prospect is very good in the future.Compared with the fine jaw crusher and the cone crusher, we can findout that cone crusher in more innovation reform than impact crusher and fine jaw crusher. Through the process experienced spring cone crusher, composite cone crusher and today"s most popular fluid pressure cone crusher. Cone crusher in crushing hard rock has obvious advantages, it is because its very wear-resisting parts. And impact crusher, fine jaw crusher broken hard stones on the machine itself wear is bigger, replacement of parts frequent. In terms of regulating the grain-size, cone crusher adjustment is more convenient and can meet the requirements of different customers on the product particle size, through the realization of automatic lifting hydraulic cylinder discharging mouth and iron protection ,saveing both time and labour.Crusher industry is the development of the chemical industry played an important role in promoting. At the same time there is a huge country particulate material crusher, crushing machine hard materials, construction waste crushing machines and more. Non-mechanical force has not yet been broken in the large industrial production use.Unlike general crushing equipment, cone crusher has distinctive characteristics and performance like wide application, high productivity, low cost, good quality and so on, which is the necessary equipment in the crushing works of all sectors. In industry, a widely used material crushing method is still mechanical crushing, mainly by extrusion, the arm pieces, break, breaking,...
