23.10.2015· Due to the more energy-efficient grinding process, Cemex® ground cement will usually have a steeper particle-size distribution curve than corresponding ball mill cements. Consequently, when ground to the same specific surface (Blaine), Cemex® cement will have lower residues on a 32 or 45 μm sieve and tend to have a faster strength development.

Get PriceThe use of tower mills as an energy efficient alternative to secondary and regrind ball milling became a common inclusion in the latter part of the previous century. Traditionally the higher energy efficiency was attributed to the difference between attrition grinding in tower mills and impact grinding in ball milling. However by far the most important factor for fine grinding is media size and therefore the breakage
Get Price01.01.2016· Tumbling ball mills are capable of fine grinding to around 20 μm with the energy efficiency increasing with decreasing media size, depending on the feed size. For feed sizes, P80, of 55 and 100 μm, Partyka and Yan [15] showed an increased efficiency with decreasing steel ball size from 36 to 5.5 mm in a ball mill.
