A survey is given of existing theories and measurements of the rheology of mould suspensions. The Casson equation gives a good description of rheology and the impeller method is very suitable for viscosity measurements. The parameters in the Casson equation can be correlated with morphology and volume fraction. Osmotic pressure has a pronounced effect on viscosity, while the pellet growth form can decrease viscosity significantly. The implications of mould rheology for the design of reactors are discussed.
