Raw Material Drying-Grinding Cement Plant Optimization

Vertical roller mills can typically handle an aggregate moisture of up to 20% in raw materials and consumes about 30% less power in grinding. Hence it is commonly preferred for grinding operation in new plants of higher capacities. However, many ball mills are still in use.

vertical roller mills in cement processing plant

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.

FOR CEMENT RAW MATERIAL Plant engineering solutions

Cement raw material has been almost exclusively ground in roller mills (vertical air-swept grinding mills) since the sec-ond half of the 20th century. Loesche was and is the pio-neer of this technology. Hundreds of Loesche mills have been used in the cement industry across the world to the present day. They operate with two, three, four and six

Larger gear drives for larger vertical roller mills

The global trend towards single-mill cement plants is unquestionable. With civil construction cost savings, higher throughput and lowered maintenance costs, the use of single large VRMs for cement and raw grinding is the optimal choice. The sheer size requires powerful, large-scale drive gear systems.
