Loesche Mills for Cement and Granulated Blast Furnace
a Loesche mill, with a grinding track diameter of only 1.1 metres, was used as long ago as 1935. However, the breakthrough in grinding this type of material on the vertical roller mill did not take place until the beginning of the 1990’s. 1935 The first Loesche mill for grinding cement clinker, an LM 11, was commissioned in Joao Pessao, Brazil.The quadropol® concept for coal or pet coke grinding, with adapted table speed and high efficiency separator sepol®, ensures a safety mill operation and serves reliable the kiln burning process.

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.Vertical roller mills are large grinding machines developed, designed and manufactured by Sinoma-tec; Sinoma-tec vertical mills feature a rational and reliable structure as well as an advanced process that combines drying, grinding, separation and conveying, which is suitable for grinding materials of different types and sizes.Vertical Roller Mills LNV TECHNOLOGY

CEMENT SikaGrind® FOR VERTICAL ROLLER MILLS
New clinker types with lower burning temperatures and/or less calcium carbonate are in the pipeline respectively and are being used already. Nevertheless, in the past decade, Vertical Roller Mills (VRM) have a clearly higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further argumentsIn fact, in the same application a Vertimill® has 50% less footprint than a ball mill. Lower operating cost Vertimill® is an energy efficient grinding machine. They tend to grind more efficiently than for example ball mills with feeds as coarse as 6 mm to products finer than 20 microns. This provides up to a 40% higher energy efficiency.Vertical mill Vertimill® Type WB TON Corporation roller
