A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis The balls which could be of different diameter occupy 30 -50 of the mill volume and its size depends on the feed and mill size...
98 International Journal of Scientific and Technical Advancements ISSN 2454-1532 Pardeep Singh, Mathematical evaluation of scale factor and shape factor for reliability analysis of ball mill in paint manufacturing unit International Journal of Scientific and Technical Advancements, Volume 4, Issue 1, pp 97-104, 2018 In 1951, Wallodi Weibull set up an mathematical model...
It is normally not a big problem but it depends on the size of the small scale mill and the operation mode In dry grinding we have close relation between small and large scale We have used small lab units with 400 and 600 mm diameter and scaled it up to 3 m mills with good results...
