Vertical roller mills are adopted in 20 cement plants (44 mills) in Japan. Results. Table Energy saving effect of the vertical roller mill. Cost estimation. About 14million US$.
Abstract: Based on screening analysis, laser size analysis, grindability and rigidity tests of samples collected on line from a cement and a power plant, a simulation of the grinding process in vertical roller mills was carried out. The simulation calculation used a breakage function, B. The results indicate that the breakage.

To calculate the needed grinding work against the grain size changing three half-empirical models are used. These can be related to the Hukki relationship between particle size and the energy required to break the particles. In stirred mills, the Hukki relationship does not apply and instead, experimentation has to be.

In the 70s, vertical roller mills became increasingly dominant for grinding raw materials main- ly for the cement industry due to their high energy efficiency and excellent drying capacity. For many years Castolin Eutectic expert know how together with our state-of-the-art technologies have been used to repair VRMs.
The amount of deformation of the rolls by the rolling force is the largest component of the vertical deformation of the whole rolling mill, accounting for 60-70% of the total . The flattening deformation of the work rolls during rolling requires corrections to the calculations of the rolling force derived from deformation theory.
