grinding theory of vertical roller mill

A vertical roller mill has grinding rollers which roll over a grinding path of a rotatable grinding table, and a surrounding nozzle ring separation area for conveying and separating gas. A coarse fraction of ground material is entrained in gas upwards in ducts from a loion that is below, at, or above the nozzle ring separation area and is transported into an entry to a material separator
