vertical roller grinding mills for grinding: • Coal • Cement raw material • Clinker / granulated slag • Industrial minerals, and • Ores The core elements of these plants are the Loesche vertical mills for drygrinding the abovementioned grinding stock. Loesche has developed and built the largest and most
Objective of this research paper is process optimization of Vertical roller mill, improvement in productivity and reduction in vibration breakdowns using seven QC tools.
LOESCHE mill was presented to the industry in December 1999, this was another innovation and since than it has been copied by many gear makers. Before the introduction of the planetary gear technology, the standard drive design of Vertical Roller Mills (VRMs) comprised gear units featuring a bevel stage and two helical gear stages.
