To ascertain the best binder ratio, mix ratios of kaolin and bauxite were subjected to varying ratios of ball clay at 5%, 10%, 15% and 20%, respectively as shown in Figure 4 and judged on consistency, holding, colour and zero cracks. Eventually, ball clay of 10% binder was found ideal for the mix ratios. Figure 4: Binder ratios.

Bauxite is an aluminium-rich ore used for the manufacture of aluminium (metallurgical bauxite) and refractory products, chemicals or cements. Bauxite is a prime important raw material for the primary aluminium industry. It is also used in a number of non-metallurgical sectors, like refractory, abrasive, cement, steel making and chemicals.

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.
