LM Series Vertical Roller Mill is used to pulverize materials, material can be pulverized into 80-400Mesh with this mill. Feed particle size 0-70mm. Production capacity 4-300 tons hour. Applicable materials limestone, coal, feldspar, calcite, fluorite, talc, iron ore, copper.1. Vertical Ring Rolling Mill Vertical Ring Rolling Mill, or VRRM for short, being discussed here, was a machine that was developed in Japan some decades ago, and had a ring-forming roll configuration which was different from the one that is seen with the currently-conventional horizontal (radial axial) type ring rolling mill.Vertical mills (such as bowl, roller grinding, ball-and-ring, 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.
