Vertical mills (such as bowl, roller grinding, ballandring, and roller mills) are mainly used for comminuting limestone, clinker, slag, lime, gypsum, and ores for the building industry, and coal in the coal preparation. They reduce raw material from a thickness of 30 mm to a very finegrained material.
Vertical roller mill is a kind of grinding machine for cement raw material, cement clinker, slag and coal slag. It has the features of simple structure, low cost of manufacture and use. Vertical roller mill has many different forms, but it works basically the same.
Vertical Roller mill has two pairs of grinding rollers, each pair of roller composed of two narrow rollers, mounted on the same axis and can rotate at different speeds. The materials fall into the center of device through lock air feeder, and hot air comes into mill through air inlet under the function of centrifugal force, the materials when they come by the annular chute.
The ufg mill® is a dry agitated media mill suitable for producing powders in the range of 40 microns down to 1 micron. The feed material is typically below 2 mm and moisture below 1%. The ufg mill® is normally operated in closed circuit grinding with a high efficiency air classifier.
