Present situation and development of domestic cone crusher

Cone crusher is located in the final stage of the ore crushing production line, therefore, it is an important equipment in the mineral processing plant. In recent years, due to the changes of market demand, home not but broken machine user or manufacturer, of cone crusher produced a great interest, first the introduction of foreign advanced cone crusher, then is the digestion and absorption, and innovation and R & D, become the crushing machine industry to focus on models. The cone crusher is in 1954 imitation of Soviet Phi 2100 and phi 1650 spring cone crusher based, designed the production of phi 1200 spring cone crusher; in 1958 and design manufacturing the large Phi 2200 spring cone crusher; in the 1970s and developed the bottom single cylinder and multi cylinder hydraulic cone crusher, has also been developed hydraulic cylinder hydraulic cone crusher. After after years of repeated research and practice, one after another to overcome the lack of spring pressure machine, low intensity of components and structure of some defects, has been mass production of new series spring cone crusher has five specifications, 14 kinds of cavity diameter of 600, 900, 1200, 1750, 22 mm of crushing old series spring cone; the bottom single cylinder hydraulic cone crusher has a diameter of 900, 1200 and 1650, 22 mm four specifications, 12 kinds of cavity type; multi cylinder hydraulic cone crusher has a diameter of 1200, 22 mm two specifications, four cavity. At that time, the domestic cone crusher has reached a series of standards, and the degree of standardization, it can be said that the product is complete, the use of reliable, by domestic and foreign (Southeast Asian countries) recognition. In spite of this, there is a certain gap between domestic cone crusher and advanced cone crusher. In order to catch up with the advanced level in the world, Shenyang Heavy Machinery Plant and introduction of the American Nuodeboge (Nordberg) Company Simmons (Symons and the rotary disc cone crushing machine (Gyradisc Crushers) technology. Domestic cone crusher and the world advanced countries in the same type of crusher, there is a gap in the quality and performance. In order to catch up with the advanced level in the world. In recent years, Shenyang Heavy Machinery Factory the introduction of American Nuo to machine Gyradisc crushers technology Berg (Nordberg) Simmons (Symons and disc rotating cone crusher, and co producing the series cone crusher products. In addition, American allis Chalmers (Allis- Chalmers) Company (AC) 84ir bottom single cylinder hydraulic cone crusher is used for crushing the had been introduced in a concentrator, and the use effect is poor, now demolished. A copper AC company to introduce 84u single cylinder hydraulic cone crusher, proved to greatly reduce the product size. Sichuan 2 Wei large hydropower station, Guangxi Tiansheng Bridge Hydropower Station by 4 48U and 66t. rotary disc crusher, both of which are used in making artificial sand. Dayawan Guangdong nuclear power station is also used two sets of rotary disc crusher. The introduction of foreign advanced crushing equipment and technology. And this undoubtedly the development of China's mines and crusher industry has very important significance. The introduction of the key lies in the digestion and absorption and the localization, in the introduction of the crusher, some factories use the very successful, but also have failed, two aspects should conscientiously sum up for the future introduction of a crushing machine and the development of domestic crushing machine industry to provide valuable experience.
