Grinding test results for zinc ore showed that it is possible to decrease the total grinding energy consumption from to kW h/t by using vertical roller mill instead of AG/SAGball mill circuit (van Drunick et al., 2010). In another test performed in the Loesche test centre in Germany, % in airflowmode and % energy savings ...
Vertical roller mills are developed to work as airswept grinding mills. Roller mills are operated with throughput capacities of more than 300 t/h of cement raw mix (Loesche mill, Polysius® double roller mill, Pfeiffer® MPS mill). Loesche roller mill and Polysius® roller mills are widely applied in cement raw material grinding.

The LOESCHE mill type LM +4 CS with a drive power of 10,000kW has been sold for an OPC capacity of 445 t/h and a CEM II capacity (with 10% limestone) of 485 t/h at 3400 Blaine.
This work concentrates on the energy consumption and grinding energy efficiency of a laboratory vertical roller mill (VRM) under various operating parameters. For design of experiments (DOE), the response surface method (RSM) was employed with the VRM experiments to systematically investigate the influence of operating parameters on the energy consumption and grinding energy efficiency.
OVER. VIEW Loesche Technology a Success Story In 1927 Ernst Curt Loesche patented the world's Loesche also introduced this technology in the first springloaded airswept mill developed by ore industry and for grinding of steel slag. him in Teltow near Berlin. And so began the unprecedented career of the Loesche roller grind A defined product particle size distribution caning mill.
Quality and reliability right from the start are the globally recognised benefits to be derived from Loesche grinding plants. As early as 1928, when the first Loesche mill came onto the market, the grinding principle of the vertical roller grinding mill, with a driven grinding track and springloaded rollers was shown to be particularly energyefficient and reduced the use of natural ...
