Kinetic approach to ball mill scale up for dry and wet

Kinetic approach to ball mill scale up for dry and wet

In this investigation detailed experimentation has been carried out to establish a relationship for mill scale-up using a linear population balance model in dry and wet grinding systems. Data were obtained in three different sizes of mill (10, 15 and 30 inches in diameter) for limestone grinding. In each case the selection and breakage parameters of the population balance model were determined.

Hold up studies in a pilot scale continuous ball mill

In the past experimental studies on mill hold-up were done using tracers and residence time distribution analysis (RTD). In one or two studies the entire content of the mill was weighed after the experimental run. Either as a result of inflexible experimental setup or difficulties in measuring hold-up in closed-circuit industrial mills via the RTD approach, the published correlation between ...

Large Ball Mill Scale Up Factors to be Studied Relative to

Abstract. Ball mills 5.5 m (18 ft) in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills, particularly when the large mills carry 40% by volume ball charges. This paper will explore factors used in scaling up ball mills, showing where the advantages of one factor can possibly be negated by another factor.
