10、</p><p>　　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 in

11、ner path serves to prepare the grinding bed, by compressing the feedmaterial as it moves under the rollers nto the high pressure grinding zone.</p><p>　　Segmented roller wear parts are made of the hardest po

17、lag grinding, a specially designed nozzle ring bypass allow the iron particles to segregate through nozzles without airflow and subsequently be removed by a magnetic separator to minimise wear of the mill internals.</

18、p><p>　　One mill, many products</p><p>　　The OK mill efficiently grinds blended cements, with a wide range of additives such as slag puzzolana, limestone and fly ash. Its versatility is demonstrate

19、d by the ability to switch between a wide variety of mixes, and to vary the particle size to meet individual needs.</p><p>　　Particle size distribution</p><p>　　Example of adjustment of particle

22、 including adjustment of the particle size distribution, can be made immediately. Adjustment of the dam ring, however, requires a mill stop, but only for a few hours. Switching between different types of products, for ex

23、ample from portland cement to slag, only requires easily made operating adjustments. Adjustment of the dam ring is not required. However, if the mill is to operate for a long time with one specifi</p><p>　　W

24、ear liners</p><p>　　The wear liners of the grinding table and the rollers are of the segmented type and are therefore easy to replace when worn out.</p><p>　　For mills grinding very abrasiva mat
