Proven commercially, the OK™ mill is the premier roller mill for finish grinding of Portland cement, slag and blended cements. The mill consistently uses five to ten percent less power than other cement vertical roller mills, and in comparison with traditional ball mill operations, the energy requirements for the OK cement mill is
1. Material layer of vertical slag mill. The selection of suitable mill material layer is the basis to ensure the stable operation of the vertical mill. Too thick will reduce the grinding efficiency; If it is too thin, the driving force of the mill will increase, which will damage the grinding roll, disc and hydraulic system. 2. Vibration of ...
In the vertical grinding slag production, vertical grinding has the following technical advantages. The first is that the vertical grinding uses the principle of material layer grinding to grind the material with low energy consumption. The energy consumption of the vertical mill system is 30% to 40% compared to the ball mill system.
