Slag is the residue after beneficiation or smelting. A few years ago, most of the slag produced was discarded or buried, and it was not effectively used, which wasted a lot of resources and polluted the natural environment. In recent years, the particle size of environmental protection has been continuously enhanced. With the advancement of technology, people have a better understanding of slag. We found that slag is an active mixed material of cement after grinding, so the slag in the industry has been integrated in the past two years The utilization rate has been improved, as the main production equipment vertical roller mill in slag processing, has been developed. There are many types of mills on the market, which mills are suitable for processing slag? Investors who invest in the slag processing industry will definitely encounter this problem in the initial stage. Due to the high hardness of slag, it is recommended to use SBM-S slag Mill to process it. SBM-S slag vertical roller mill is our company based on many years of vertical roller mill R & D and production experience, for the special product of granulated blast furnace slag, through the multi-unit cooperation of the professional team dedicated research, the vertical roller mill thermal system calculation, equipment selection calculation , The main parameter calculation, the powder separator calculation and research and development and design of ultra-fine grinding equipment, which integrates grinding, drying, classification in one, has the characteristics of high grinding efficiency, strong drying capacity and so on. The process is simplified, the area is small, the investment is saved, the power consumption is greatly reduced, the service life is long, and the ultra-fine grinding innovative process technology with high operation rate is realized.
