RESIDENCE TIME DISTRIBUTIONS IN BALL MILLS: Particulate ...

ABSTRACT A review is made of the methods and theory of measurements of residence time distributions (RTD's) in mills. Literature data on RTD's is assembled. 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 …
