(PDF) A Survey and Analysis on Electricity Consumption
In the whole process of cement production, the electricity consumption of a raw material mill accounts for about 24% of the total. Based on the statistics of the electricity consumption of the rawA study conducted by Gerold et al. (2012) showed that VRM was able to grind copper and slag with the energy saving of 22.9% and 34.4% respectively compared to conventional grinding circuits. Wear rate is another criterion that is needed to be considered. In this context, Erkan et al.

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 In the production of long-length round metal products (pipes, reduced solid blanks, and rods), various technological processes are used [ 1 ]. Among them, the helical rolling method in a multi-roll mill, the groove of which is formed by three or more rolls without a guide tool, is widely used. Their advantages are the possibility of fastModernization of Helical Rolling Technology in a Multi-Roll Mill
