Vertical-roller-mills (VRM) are an energy-efficient alternative to conventional grinding technology. One reason is the dry in-bed grinding principle. Results of extensive test works with two types of magnetite iron ores in a Loesche VRM are presented here.

Our highly-flexible vertical roller mills (VRM) are energy-saving grinding solutions that cater for differing types of material.

In the study the advantages of vertical roller mill are discussed over ball mills. VRM construction, its process and parameters which affects the performance and …

Our ATOX® coal mill has large rollers with great grinding capability of all types of coal, tolerating moisture levels up to 20 percent. For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent.

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.

Roller mill is a type of grinding equipment for crushing materials by pressure between two or more rolling surfaces or between rolling grinding bodies (balls, rollers) and a track (plane, ring, and table). The roller mill with several grinding rollers as working components rolls along the grinding ring or …

Milling specialist Loesche's Vertical Roller Mills (VRM) can simplify the beneficiation process using improved liberation of the targeted mineral within the ore, even with complicated sulphide ores.

In China almost no work has been done on the simulation of multi-factor industrial manufacturing systems. This paper describes the simulation of the grinding process in vertical roller mills. It is based on actual experimental data obtained on a production line at the plant and from lab experiments.
