o Finished grinding may consume 25 – 50 kWh/t cement, depending on the feed material grindability, additives used, plant design & especially the required cement fineness. 1. Introduction. Cement manufacture is energy intensive. ➢ Cement grinding is the single biggest consumer of electricity in the manufacturing process.
ensure availability of the mill system. Benefits. The increased knowledge and subse- quent implementation of maintenance procedures will greatly improve the productivity of the mill and increase plant efficiency. Seminar plan. - Cement ball mill types. (Design, operating principles and fundamentals). - Design features of.
on standard modules. 2. The FL ball mill is designed for grinding of clinker, gypsum and dry or moist additives to any type of cement. The mill may operate in either open or closed circuit and with or without a pre- grinder to achieve maximum overall grinding efficiency and high flexibility in terms of product quality.

Systems have been designed, including a de-agglomerator and separator, that will deliver material of cement fineness. However, particle size distribution is again a problem, and roll presses are now increasingly popular as a "pre-grind" process, with the cement finished in a single chamber ball mill. This gives good cement.
