Large Mills for Dry Raw Material and Clinker Grinding

Abstract

The development of grinding mills, especially in the last few years, shows a continuing trend to larger units. Particular attention must be given to the drying process during dry grinding. Several grinding methods are available, depending upon the material to be ground, and the optimum method must be carefully selected in each case. Special consideration must be made with large ball mills to assure the utilization of all waste heat from the kiln for the drying process. In many cases a roller mill represents a good alternative.
