The ball mill is one of the high fine grinding machines, widely used in the industrial production.There are many kinds, such as tube ball mill, rod ball mill, cement ball mill, horizontal ball mill, Ball mill is suitable for grinding all kinds of ores and other materials.
The ball mill, but they can also be used as a one-stage grinder.The absence of, or reduction in the number of, balls means they can be less costly to operate than ball mills.SAG mills of over 40-foot diameter have been constructed.Like the ball mill, the AG/SAG mill will have a critical rotation speed above which grinding ceases.
The mean residence times indicate that some industrial mills are operated in the over–filled condition, leading to poor breakage conditions.Although all RTD's are somewhat similar on a dimensionless basis, there appears to be no consistent pattern to explain differences from one mill to another.
The sample feed size depends on the mill and can be as large as 8 mm.If the feed size is larger than this then the sample must first undergo preliminary size reduction.
