A method is shown for producing food grade hydrated lime. A source of raw, hydrated lime is first passed through a classification step which divides the raw hydrated lime into a first fine stream and a first coarse stream. The first fine stream is passed through a further separation step and, without being recombined with the first coarse stream is separated out to form a very fine sized ...

In the model presented here, all design proportions were according to Rietema's optimum design as per Table 6.1. The model was tested with two materials: chalk of density 2780kg m -3 and alumina hydrate of density 2420 kg m -3. The suspending liquid used in the hydrocyclone tests was water with 0.1% Calgon as dispersing agent.

The main driving force for the use of hydrocyclones as product classifiers is the product requirement of the aluminium smelters (Electrolysis). The well-known term of "Sandy Alumina" describes an aluminium oxide with a minimum content of fine particles -45µm. A typical composition of a "Sandy Alumina" is given in Table 1.
