Energy-Efficient Technologies in Cement Grinding
Vertical roller mills have a lower specific energy consumption than tumbling mills and require less space per unit and capacity at lower investment costs. Vertical roller mills are developed to However, the unit cost for wear parts for a ball mill is much lower than for a vertical roller mill. For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is Cement grinding Vertical roller mills VS ball mills

Modeling and simulation of vertical roller mill using
The application of vertical roller mills (VRMs) for ore grinding is a part of the strategies against rising energy consumption (Reichert et al., 2015). The VRM technology was introduced in the mid-'90s for grinding clinker and slag by LOESCHE (Schaefer, 2001). Fig. 1 illustrates the grinding parts of a Loesche vertical roller mill.The Institute of Mineral Processing at the Montanuniversitaet Leoben in cooperation with the company CEMTEC has developed a pilot scale, 200 mm table diameter, vertical roller mill for energy controlled laboratory tests.The mill provides the technical options to vary process parameters like air-flow, mass flow, grinding force and An energy based comparison of vertical roller mills and tumbling mills

Modelling of vertical spindle mills. Part 2: Integrated models
There are three basic structures among the coal grinding, t: Air-Swept or Wet Tumbling Ball Mill, Roller-Race or Ball-Race Mill and Hammer or Impact Mill [7–10]. The type of the mill and its efficiency depend on the type of coal, its moisture, input and output fraction of the material and the grinding susceptibility of the coal.
