subject: To Promote New Crusher Is Inevitable [print this page] With the rapid and stable development of China's national economy, the comprehensive utilization of mineral resources and related industries has been a rapid advance; China has built over more than 10,000 large and medium-sized state-owned mines and more than 200,000 township collective enterprises. The national total ore mining more than 5 billion tons of mining industry output value of 400 billion yuan. In the metal concentrator, crushing and grinding process equipment costs account for about concentrator all 65% -70% of investment costs, power consumption is about the whole plant power consumption 50% -60%, while steel consumption accounts for about the whole plant more than 50 percent of steel consumption.
East Granville machinery and other enterprises in Zhengzhou, along with economic development, more and more nervous energy, energy saving is the urgent task of the concentrator. Thus reducing the cost of preparation operations in mineral processing, reduce energy consumption, steel consumption, mainly to reduce the cost of broken ore and grinding. Ways to reduce the grinding input costs through the improvement of the mill itself, such as hydrostatic bearing to reduce the energy consumption of the grinding, can also reduce feed particle size, namely to reduce the fragmentation products of the final particle size, which so that the total cost of the dressing to a significant decline, and ultimately more crushing to less grinding to improve mineral-effective. To achieve the goal of more broken and less grinding, selection of good and efficient crusher high production performance and crushing performance is the key.
To meet the needs of the modern concentrator excellent Crusher, East Granville machinery and other experts agreed that: first, through the use of successive approximation broken, making the crusher to achieve the highest efficiency of; is to make use of laminated crushing principle and give full play to the role of the laminated crushing and secondary crushing, so as to achieve a high fragmentation rate and excellent chronology of results. Under such circumstances, to promote the new crusher is the inevitable trend of development of mining.
