Effects Of Slurry Holdup On The Pool Volume Of A Batch Mill

Sep 01, 2017 1. Introduction. The efficiency of a wet ball mill is dependent on the size of the pool of slurry that may form around the toe region of the media charge e.g. Tangsathitkulchai, 2002, Tangsathitkulchai, 2003, Mulenga and Moys, 2014.In order to determine the presence of the pool, various types of sensors can be used to this effect.

Modelling Mineral Slurries Using Coupled Discrete Element

In addition, DEM parameters exhibited limited impacts on rheology of the solids-liquid mixture, particularly at low solids concertation and high shear rate states. The findings suggested that the non-Newtonian based SPH-DEM method should be used to more accurately model the slurry flows within grinding mills.
