Optimization Of Cement Grinding Operation In Ball Mills
jul 18, 2016 several energy efficient options for cement grinding are available today such as vertical roller mills, roller presses and clinker pre-grinders with ball mills. ball mills have been the traditional method of comminution in the mineral processing industries and continue to operate with old generation vertical coal mill, also known as coal mill, for superfine grinding of raw coal, soft coal specifically for cement, power plant, steel mill and other fields. its special design structure and production process creates the higher production efficiency with lower energy consumption, less dust, lower noise than ball mill, which meets national get the vertical roller mill is a kind of mill equipment which meets the requirements of energy saving and emission reduction. It integrates crushing, grinding, drying, grading and powder collection. the utility model can solve the problems of low capacity, high energy consumption and high maintenance cost of the ordinary pulverizer.vertical roller mill can replace ball mills or tube mills used for preparing coal. today vrms with capacities up to tph are the dominant technology for coal grinding. grinding media wear in a vrm will only be to gton of coal powder, as compared to 100 gton of coal powder in a ball mill.
