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
Roller mill Wikipedia. Fourroller mills Fourroller mills have two sets of rollers. When using a fourroller mill to mill grain, the grain first goes through rollers with a rather wide gap, which separates the seed from the husk without much damage to the husk, but leaves large grits.

what is magnetic separation method used in industry. Magnetic separation is one of the basic methods used in concentrating. It is used when separating minerals with different magnetic properties. The separation method is usually used in iron ore beneficiation, but it is also often used as part of different types of combination processes.
The present invention relates to a separator, a mill having a separator and a method for separating a gassolids mixture. BACKGROUND OF THE INVENTION. By separation is meant in general the sorting of solids according to certain criteria such as mass density or particle size.
Vertical spindle roller mill. Similar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found in utility plants. Raw coal is gravityfed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table.
Bowl mill. Similar to the vertical roller mill, it also uses tires to crush coal. There are two types, a deep bowl mill, and a shallow bowl mill. High speed Attrition mill. The attrition mill is a device for mechanically reducing solid particle size by intense agitation of a slurry of material being milled and coarse milling .

ABSTRACT OF THE DISCLOSURE A particle classifier apparatus and method for separating coarse particles from a mixture of particles carried in a gas stream, for preferred use in combination with a coal crushing mill. In the classifier, the gassolids stream is passed through a plurality of internal fixed vanes for imparting a rotational motion of the particles.
Application of KTM mills KTM vertical roller mills are used for grinding of cement, lime, glass, as well as a number of chemical and metallurgical materials. With its data base and test equipment PSP forecasts operating results of many more materials of other industries where coarse, fine or very fine grinding is required.
