Second Hand Vertical Mills

Mineral Grinding Plant

The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the majority of the particles in the bed are considerably smaller than the thickness of the bed. It is thus necessary that a stable and consistent grinding bed is formed between the rollers and the table of the vertical roller mill, able to sustain such a pressure without the material being squeezed away from the pressure zone.

Vertical Mill in India

Vertical roller mill is good choice for limestone powder processing. The mill can be used as a pregrinding mill too due to its low energy consumption. Since the specific pressure of the grinding runners is relatively low, no firm agglomerates are formed in the grinding process, and therefore it is not necessary to use disintegrators before separation.

The vertical mill can also be used for grinding of all silicate materials up to 8 degree of the Mohse scale of hardness such as ceramic material, cement raw material, slag, clinker, quartz sand, lime, bentonite, scrap glass, etc. There are also second hand vertical mills in India with low price, please contact us for more information.
