NETZSCH Ecutec39;s Atlas Vertical Roller Mills has been developed for more efficient fine grinding of soft to medium hard materials. The Atlas is a roller air swept mill designed for continuous operation with minimum maintenance.
Grinding theory of vertical roller millGrinding in roller mill is effected by shear and compaction.The effective grinding In the mill depends on many parameters.Important among them area : the gripping angle, nip angle,maximum grinding pressure, grinding bed thickness between theGrinding surfaces, rolling friction factor µGripping angle It is the angle between the surface of roller and table.
Grinding and separation efficiency of vertical roller mill were evaluated. In addition to these, performance figures of vertical roller mill and conventional closed ball mill circuit were compared....

The vertical roller mill is used to grind the material by using the principle of material bed pulverization. It gathers materials for grinding, conveying, powder selection, drying and separation of metal blocks and medium ore.
In the vertical roller mill the air is discharged from the ported air ring with high velocities. These high velocities are required to prevent coarse material dropping through the air ring...
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 and low cost of manufacture and use. Vertical roller mill has many different forms, but it works basically the same.
