One distinction between crushing and grinding equipment is that the working surfaces of crushing equipment do not make contact with each other during size reduction. CrushabililY may be defined as the ease of crushing a sample under standard conditions. Various test ing procedures may be used to measure crushability." (Horst 1985, p. 3A-5).

Primary crushing brings run-of-mine ore down to a maximum size of the order 4″ to 6″ in average diameter; secondary crushing receives feed at −6″ and reduces it to below "Dry" crushing includes work on ore as mined, which may be somewhat moist when delivered. It is succeeded by comminution in water, arbitrarily called "grinding".

People have always tended to regard the crushing and screening section of a flowsheet involving grinding mills simply as a function of feed preparation for those mills. Consequently, in most operations, crushing plant opera- tors produce mill feed as fast as possible. But the fastest feed rate produces the coarsest material, causing any sub-

3.1 Introduction to Crushing and Grinding of Bauxite. The most common initial process step to feed an alumina refinery with bauxite is the crushing or sizing of the raw bauxite material that is extracted from the mine. The feed material is crushed or sized so that it is conveyable, as well as correctly dimensioned, for the next step in the process.
