OK Vertical roller mill Main features: OK vertical roller mills use 30%-50% less energy than ball mill systems. Simple layout and fewer machines in the mill circuit high run-factor and low maintenance costs. Excellent drying capability when grinding blast furnace slag or blended cements with wet components . Roller and table profile improve operating stability and reliability. Consistent cement quality with easy to adjust quality parameter Special design features for iron removal during slag grinding minimize wear Optimal wear-protection all internal surfaces Space-saving design reduces civil construction costs Flexibility to operate with two or four rollers guarantees long term availability. Application advantages Proven commercially, the OK mill is the premier roller mill for finish grinding of portland cement, slag and blended cemtrents. With a 30%-45% reduction in the energy requirements for cement grinding and 40%-50% for slag as com-pared with traditional ball mill operations, the OK mill can contribute significantly to your profitability and competitiveness. The design combines the drying, grinding and separation processes into just one unit, thus simplifying the plant lay-out. A low noise level makes outdoor installation feasible, substantially reducing civil construction costs and improving the working environment. Because of its highly effective drying performance, the OKmill is a natural choice for grinding blended cements with one or more wet components Design advantages The OK mill uses a hydro-pneumatic system to press its grinding rollers against the material bed on the roatting grinding table. The grooved roller profile has two grinding zones, an inner and outer. This creates a high and concentrated grinding pressure on the outer path, allowinair to escape into the grooved centre. The inner path serves to prepare the grinding bed, by compressing the feedmaterial as it moves under the rollers nto the high pressure grinding zone. Segmented
