The successful application of spring cone crusher in the metal mines
Currently, most metal mines processing plant shredding process , power consumption, steel consumption and raw material consumption greatly , power and steel consumption constitute the main part of the entire cost of production , accounting for more than 60% of the cost of processing plant . Grinding, its energy consumption per unit than fragmentation is much higher , accounting for 89% -93% of the entire mineral crushing operations , accounting for 40% -70% of the processing plant as a whole . Therefore, in the metal mines to implement energy saving , can have an enormous social and economic benefits .
Metal ores of the national economy , national daily life and the defense industry , cutting-edge technology and high-tech industries indispensable basic materials and important strategic materials . The production of steel and nonferrous metals are often considered the embodiment of a national strength . Bonanza less of metal ores , low grade ore reserves , but low- grade , almost all of the lean ore ; distribution of the relative concentration , mainly in Eastern Liaoning , northern Hebei Province , and western Sichuan ; deposit types , ore type is relatively complex . Therefore, the vast majority of iron ore after beneficiation can be smelted and development investment , high production costs , lack of market competitiveness .
"More crushing mill" is a smash engineering widely recognized as an important way of saving energy , the material layer of crushed a major breakthrough in the grinder and reasonable . Spring cone crusher is based on the material layer to smash the " mechanism , to achieve the energy saving " more crushing mill " on behalf of one of the devices .
Compared with conventional crushing equipment , spring cone crusher crushing of materials processing equipment , to achieve selective crushing of materials to meet the requirements of the new process "more crushing mill" has a great crushing ratio , low power consumption unit , can be broken advantages of any hardness of brittle materials , which greatly simplifies the fragmentation of the production process , reduce the particle size of ball mill into the grinding to increase the mill output China to the savings of energy and steel consumption of the crushing system ;The same time, due to the crushing of the simplification of the grinding process , can save the investment in equipment and infrastructure , reduce operating positions and operating costs , with very significant economic and social benefits , is very applicable to the materials of metal mines broken . Promote the use of technology for metal mines , upgrade, enhance their strength , as soon as possible to shorten the gap with foreign enterprises in the cost of production , technology and equipment level , to improve the competitiveness of China 's metal mines in the international arena , are of great practical significance .
