Vertical mills tend to produce cement with a higher value of ‘n’. Values of ‘n’ normally lie between 0.8 and 1.2, dependent particularly on cement fineness. The position parameter is, of course, lower for more finely ground cements. 2.10.5 Characterisation of Separator Efficiency in a Ball Mill Circuit 18
The cement industry is one of the most intensive energy consumers in the industrial sectors. The energy consumption represents 40% to 60% of production cost. Additionally, the cement industry contributes around 5% to 8% of all man-made CO 2 emissions. Physiochemical and thermochemical reactions involved in cement kilns are still not well understood because of their complexity.

Aug 02, 2013 In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
For the preparation of cement raw material, cement, and granulated blast-furnace slag with small to medium output rates, the MVR mill with conventional drive is the right choice. This mill type is by the way the core piece of our modular ready2grind system.
Mar 01, 2006 Effect of mill speed, particle load, balls load and ball size on energy efficiency factor. Fixing the operational parameters to these optimal values, Table 2 reports the energy efficiency factor for various mass compositions of the coarser cement clinker fraction (2.8–2 mm) in the feed.
