zhengzhou, China (prHWY.com) May 7, 2012 - Developing course of crusher
The development of modern crusher is from the Western Industrial Revolution. In 1858 , jaw crusher was born in the United States, it is designed by Americans Blake. The jaw crusher used for crushing operations can also be used in small operations. Especially for underground crushing operations and small mobile crusher unit.
World War II, the crusher came into being, the crusher is a new high-efficiency crushing equipment, the designer of the first crusher is black Dodson Dr the originalGrumman. It can be used for cement, asbestos, thermal, glass, chemicals, construction materials, metallurgy and other industrial sectors to be used for coarse limestone, asbestos factories, coal, calcium carbide and other brittle materials, crushing. The crusher can be divided into single-rotor and dual-rotor two specifications with its rotor diameter and length.
The world's first cone crusher is by an American Red Star brothers from the initial design, so the better manufacturers of cone crusher machine name or named to Red Star. Cone crusher in 1920 and applied to the concentrator. 1948 a U.S. company developed a hydraulic cone crusher. It into the crushing chamber of the non-debris discharged in the operation of the machine, and can adjust the size of the port of discharge in the operation, broken items with uniform size; to the 1970s, with the development of science and technology, has been developed to be used to control hydraulic cone crusher with automatic controller. The cone crusher has the advantages of big crushing ratio, high efficiency, less power consumption, uniform particle size.
With the development of science and technology, broken machinery development today, has made great progress. In the 1990s, broken machinery production and sales volume has grown rapidly, add the broken machinery production companies increasing, broken machinery manufacturing enterprises have been as many as a thousand, can produce 0.5 ~ 30t crusher, 4 ~ 24t static roller crusher and 16 ~ 30t mobile crusher station and other varieties of specifications more complete series of products, basically formed a complete crusher manufacturing systems able to self-development and production, the gap between the technology level and international advanced level is gradually reduced. This situation of high growth, there will be broken mechanical parts industry into a new period of development.
