These years, china control SO2 discharge more and more seriously, and flue gas desulfurization of thermal power project which on buildings or under buildings are more and more widen. For the sake of control pollution of SO2, we transport electric from west to east. Environmental protection department should measure flue gas discharge level of electric manufactory. Control the SO2 discharge of power plant. Improve the quality of environment, protect human health. It's important that make discharge level meet standard requirement. YGM series High Pressure Suspension Grinding Mill which Shanghai Jianye produce approved China standard. These series are main equipment in electric manufactory desulfurization & High speed freeway. To some extent, they reduce the power consumption or increase the system output. Also in the process technics, compared with the closed-circuit grinding, opened-circuit grinding process is only more saving invest, and more facilitated in the maintenance and management. However, the adjustment of closed-circuit grinding is much more convenient and more adaptable to the quality changes and moisture of raw materials. Due to the grind ability of the clinkers, even if clinkers are supplied by different supplier or raw materials are from different places. The capacity and final fineness of the closed-circuit grinding mill production will not changed too much.To this point, the capacity and final fineness of the closed-circuit grinding mill production are not changed much even if raw materials are from different places. Therefore, it has more advantages than opened-circuit grinding. Some experts on recommending opened-circuit grinding believe that the particle size distributions in the open-circuit cement grinding process are wider, thus the consistency standards demand less water. So the opened-circuit grinding is welcomed in concrete mixing station. To choose which one, the cement factory should be based on the actual situation of their choice.
