The vertical roller mill itself is equipped with a powder concentrator which can remove fine powder in time reduce the phenomenon of overgrinding and improve the grinding efficiency. The vertical roller mill is less power consuming. The energy consumption of a vertical roller mill is around 75 of that of a ball mill of the same capacity.
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 coppergold ores are usually sorted by flotation.

VERTICAL ROLLER MILL DRIVE GEARBOX Products VERTICAL ROLLER MILL DRIVE GEARBOX Roller Mils are directly driven bevelwheel planetary gears or bevel cylindrical gear units. The gear unit represents an almost integral component of the mill. The output flange of the gear unit is rigidly connected with the grinding table.
Oct 12 2021The order was for two vertical roller mills (VRM) one type LM for grinding cement raw material and one LM 4 CS the biggest Loesche VRM built for grinding cement clinker. Loesche worked with Renk to develop the Compact Planetary Electrical (COPE) drive due to the high power requirements of the LM 4 CS mill.
Ordinary Vertical Roller Mill Output size (μm) 22180 Features of equipment The equipment scale of ordinary vertical roller mill is large and the output is high which can meet the largescale production of the enterprises. The stability of vertical grinding mill is high and the investment cost is relatively high.
A vertical roller mill has a rotary grinding table (1) grinding rollers (3) and a nozzle ring (13) surrounding the table for providing an air stream to entrain ground material. Downstream of each roller is a scraper (20) with a nozzle for directing a blast of air onto the crushed material leaving the roller to break up the material so that finer fractions pass into the conveying air stream
The vertical roller mill (VRM) is a type of grinding machine for raw material processing and cement grinding in the cement manufacturing process. In recent years the VRM cement mill has been equipped in more and more cement plants around the world because of its features like high energy efficiency low pollutant generation small floor area etc.
