Operational parameters affecting the vertical roller mill …
In this study, pilot scale tests were performed with a mobile vertical-roller-mill grinding plant to investigate the relationships between operational parameters. The identification and quantification of the grinding parameter relationships was carried out to implement these relationships into a computational vertical-roller-mill performance model.

Copper ore grinding in a mobile vertical roller mill pilot plant
Promising results obtained from cement industry encouraged the test studies on mineral grinding. van Drunick et al. (2010) presented VRM pilot plant test results where zinc ore was ground. In his study it was concluded that the total specific energy of the AG/SAG-ball mill circuit, which was 20.11 kWh/t, was reduced to 11.40 kWh/t by using …
Grinding of cement clinker in vertical roller mills is a
Grinding of cement clinker in vertical roller mills is a technology introduced by LOESCHE, first used in 1935. Almost 40 years ago LOESCHE introduced the first vertical roller mill to grind cement clinker and granulated blast furnace slag in one process.

The new leader in grinding technology
The Loesche VRM has adaptable grinding modules which are already proven to be the way forward in other mining industries, allowing for variant mineral ores to be milled efficiently to the required particle size. 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 …
Vertical Roller Mill for Sale
- Due to the high air velocity and the heat transfer rate of airflows at the air duct ring, small particles in the material can be dried instantly.
- The vertical roller mill itself is equipped with a powder concentrator, which can remove fine powder in time, reduce the phenomenon of over-grinding and improve the grinding efficiency.
- The vertical roller mill is less power consuming. The energy consumption of a vertical roller …
