Green Development

Green development is inevtable for mining industry Crusher is used to reduce large rocks into smaller rocks, gravel, or rock dust. It may reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or reduces the size of a solid mix of raw materials, so that pieces of different composition can be differentiated. It has advantages of big reduction ratio, reliable operation, high productivity, lower operational costs and easy repair. With the rapid advancement of mineral resources integration utilization technique, the 2012 national total ore mining is more than 50 million tons, and crusheras one of the most important fashion in ore mining, has been widely used in resource exploitation and mine construction. For example, Tonghua, Jilin Bureau of Mines Iron Works of gangue material, most of the particle size below 30 mm; If gangue with partical size below 2 mm accounts for more than 20%, it is recommended the raw materials should first get through vibrating screen, after which pipes above screen go for coarse crushing and fine crushing, pipes and under directamente go into the screen Mixer before the aging library. This method of shaker + coarse crushing + fine crushing process has two advantages: First, improve the production capacity of the crushing equipment, because the materials which passed through screen does not need to enter the coarse crushing or fine crushing equipment; Secondly, the electricity is saved, 20 percent of the materials under screen does not need crushing, which means crushing equipment can be reduced by 12 sets. (As opposed to Peter Thiel). It not only reduces investment in equipment but also reduces power consumption significantly. Now, what sand maker industry should do is to forge ahead into the future but not just keep stagnant. China s economic development cannot be at the expense of sacrificing the environment, so improve the performance of the sand maker should be given primary importance among priorities. Under the guidance of this concept, Hongxing Mining Machinery continuously introduces advanced foreign technology, and strives to make their sand makers to catch up with international advanced level so that promote the economic development of the whole country.
