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.

Some experienced operators favor them in preference to any other type of crusher for the final crushing stage ahead of fine-grinding ball mills, as one example. They are also used in.
grindability affects the capacity of grinding, type of mill and roller pressure. The capacity of the mill is calculated. Using G=K * D 2.51. Where, G is capacity of the mill, K1 is roller mill coefficient and D is table diameter. 2. PROCESS CONTROL OF VRM. The conventional control system of VRM composed of field staff to adjust.
Complete replacement of ball mills by vertical roller mills (VRMs) with an integral separator – as opposed to the use of VRMs as pre-grinding to ball mills – is . Using VRM in finish grinding, Hubei Yadong Cement Co, Ltd. achieved capacities and unit energy consumption values of 217.5 t/h and 30 kWh/t in producing of.
