Aug 01, 1999 A pilot-scale mill was designed and built that allowed continuous measurement of slurry hold-up for a wide range of operating parameters. Experiments were carried out to study the effects of feed rate, feed percent solid, mill speed, and discharge trunnion diameter on the slurry hold-up, mean residence time and the particle size distribution.
Sep 10, 2018 Jun 01 2009 Comparative tests were conducted using the different pre-assembled ball charges given in Fig. 1 in a pilot scale ball mill having 1.2 m inside diameter and 0.6 m length. These six different ball media grading used during the tests runs was identical to industrial standard ball mill media proposed by Bond with balls between 70 mm and ...
Prediction of continuous steady-state ball milling using the traditional population balance model requires knowledge of several functions, namely those describing the rate and distribution of breakage products, the mass transfer relationship between the mill hold-up and the discharge, the mode of transport within the mill, as well as the description of internal classification, whenever present.
Sepors 16 x 32 continuous ball or rod mill is ideal for pilot plant studies or small scale milling. The unique hinged torpedo tube end plate on the discharge side allows the unit to be changed from continuous to batch mode within minutes. In continuous configuration, it can be combined with a Sepor spiral classifier, screens or ...

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 ...

Abstract Batch grinding kinetics with assumptions is applied to continuous tube milling to describe the grinding performance, relating the degree of size reduction to the milling conditions including the scale-up variables. As to the scale-up effect on the degree of size reduction, the trend predicted is confirmed with that observed in industrial cement mills in reasonable agreement.
Note that this analysis suggests that direct scale-up of a commercial mill using eq. 15 is only appropriate when reference mill data are available for a mill having the same dimensionless residence time distribution and classifier efficiency, as well as the same dimensionless ball load, mill speed, etc., as the full-scale commercial mill.

Jun 11, 2020 The purpose of the current study was to improve the understanding of the mechanism of slurry flow in wet overflow ball mills. A pilot-scale mill was designed and built that allowed continuous measurement of slurry hold-up for a wide range of operating parameters.
Even worse laboratory tests may even be done in batch mills, which can not indicate size distribution for a continuous discharge mill. This accurate scale up is different than scale up for ball mills or other stirred milling technologies. In ball mill laboratory tests 25mm balls in a small laboratory ball mill have different trajectories and ...
