Inquiry OnlineOct 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 .
