High Pressure Roller Mill DM GuangYi-Mill
DM high pressure roller mill is designed specifically for manufacture metallurgical and mining industry. Our company was based on the roller mill in operation at work, where rolling material could not compromise with the hydraulic cylinder, resulting in the equipment increasing energy consumption at work and powder grinding efficiency reduced so on. At last, our company researched and developped successfully new high-pessure roller mill patented products. In operation, it works with low power consumption and coarse grinding operation in ore grinding and ore broken progress, also can be crushing 40-120mm block of mineral aggregate to 3mm to make the system beneficiation and grinding capacity have sizable promotion. DM is applied to metallurgy, mine, chemical engineering and it can be used in all kinds of materials'grinding that the mohs hardness is under9.3, while the original milling yield is incerased by 30% to 80%, the power consumptionper unit area yield of the system is reduced by 30% to 50%, so it reduce the cost of processing.

Five Advantages
1. Saving energy, high pressure roller grinding process of super finely instead of traditional broken-grinding technology, comprehensive power consumption is reduced above 60%, and steel consumption is reduced by 40% or more.
2. High output, ratio of reduction is big, and it can be crushing 40-120mm block of mineral aggregate under 3mm, the stand-alone capacity can meet 20t/h to 1000 t/h production.
3. Saving investment, roller surface is high hardness and strong abrasive resistance and the use of carbide steel, so its service life is as high as 20000h. The floor area of the equipment is small, the investment province, so it can save construction investment.
4. Good environmental protection, in operation, the noise of the equipment is small, dust pollution is less, and the roll work steadily, in addition its utilization rate is as high as 95% or more, as well as it can be easy to maintain on line.
