Slurry rheology affects both the breakage behaviour and the mass transport mechanism in a grinding mill, and hence, influences the milling energy efficiency. The present authors are aware of over 40 references dealing with rheological effects on particle breakage, mass transport, mill power draw, and the use of grinding aids.

The wet grinding of materials in most industrial grinding devices can be significantly influenced by controlled changes in slurry rheology. Thus, pulp density, the level of fines present, and the pulp chemistry conditions are all very important to maximizing throughput. This paper will present a brief summary of what grinding studies involving ...
