Jan 07, 2015 · Specific power consumption for clinker/gypsum grinding in a ball mill should be approximately: 3000 cm2 /g 24.4 kWh/t 3200 cm2 /g 26.8 kWh/t 3400 cm2 /g 29.4 kWh/t 3600 cm2 /g 32.0 kWh/t 3800 cm2 /g 34.7 kWh/t 4000 cm2 /g 37.5 kWh/t Note: The specific power demand of large grinding units is 10-15% better than that of small mills. 8.1
Oct 23, 2015 · Better product quality can be achieved as compared to the ball mill product due to the better options for separate grinding. For example, in additive cement production, the blast furnace slag has to be ground to Blaine values of 5,000 cm 2 /g. Water demand and setting times are similar to that of a ball mill cement under comparable conditions
