mill with a 30 mm graded ball charge and a 30% filling degree. The mill discharge pulp density was increased from 68.8% to 75.9% solids. The data is summarized in Table III. The example in Table III illustrates that the density has a large influence on the grinding efficiency. In this case, the
Factors Affecting Grinding Efficiency Hammer Mill. Factors Affecting The Performance Of The Sag Mill Factors affecting grinding efficiency of ball mill mining, effects of grinding media shapes on ball mill performance grinding ball size distribution inside an industrial mill was analysed in terms of, grinding is generally an inefficient process and there are many factors that can affect
SAG mills are the main workhorses in the majority of comminution circuits globally. They need to be fed and kept working round the clock. But challenges can arise when capacity is not optimised causing unnecessary downtime and liner wear leading to the one sound operators do not want to hear - the sound of the mills standing still.
important factors affecting the SAG mills performance. Some oper-ations have recognised an opportunity in the relationship between feed size and mill performance and manipulate feed size to obtain efficiency improvements (Morrell and Valery, 2001). The specific energy does not just depend on ore competence but also on factors
The SAG mill pinion energy is determined from the SAGDesign™ testwork results as follows : W SDT = revs (16,000 + m s)) / (447.3 m s) where : W SDT = AG/SAG Specific Pinion Energy from a F 80 of 152.4 mm to a T 80 of 1.7 mm, kWh/ton ground revs = Cumulative number of SAG test mill revolutions to 80% passing 1.7mm m s = SAG mill feed sample ...
