Abstract

Comminution is carried out in a mill with a positive transport capability, upon a solid in a mixture of a pasty or cohesive consistency. The efficiency of comminution, in terms of the fineness of the powder produced, and of the power needed to produce it, is maximised by controlling the amount of liquid in the mixture. The mixtures examined are of coal in water, coal in oil, zinc in water, mica in water, and limestone in water.
