Vertical cement mill is a kind of vertical roller mill, also known as VRM cement mill, mainly used in the grinding production of cement clinker. Our company absorbs the latest grinding technology from Europe and combines with the market demand of grinding industry to develop a new and improved vertical cement mill.
The job of grinding is done by the Vertical Roller Mill, which works like a cyclone to create a fine dust of evenly sized particles. As the feed is ground on the horizontal grinding table, hot air is pushed upwards from underneath forcing the smallest particles to rise.
The VRM, depending on the roller size, has a high reduction ratio; feed from 80 mm to 140 mm to a product of P80 at 75 µm in one pass, the mill is a closed circuit on its own having the comminution and classification of product in a single machine. Sulphide copper-gold ores are usually sorted by flotation.
