vertical roller mill

can process many materials such as clinker, slag, gypsum, fly ash or limestone to produce various cement types of various finesse. The mill is part of a process that begins at the quarry. Only after the initial material has been through the raw material grinding, preheater, kiln and the cooler it reaches the finish mill where additives are added and the final product is obtained. Both Loesche and its customers are essentially concerned with this final product and its properties which are influenced by all stages of the cement making process. what is the centre of the rotating grinding table. The product is then driven outwards by centrifugal forces, underneath the rollers where the grinding takes place. Ground material moves over the dam ring and goes up with the gas flow to the classifier. The material has either reached the required fineness and leaves the mill towards the bag filter or is sent back for further grinding, via the grid cone onto the grinding table. Lumps, which escape the rollers and are too heavy to rise with the gas flow drop through the louvre ring to a reject system and are then fed back via the reject system. Raw mills or coal mills operate using the same size of rollers
