Abstract
Fine and ultra-fine grinding have several applications in most of industrial fields such as advanced ceramics, porcelain, cement, paper coating, plastic and pigments. The selling price of ultra-fine minerals is highly increased compared with conventional ground minerals. Different industrial minerals that are most frequently used as fillers and extenders are alumina hydrate, barite, calcium carbonate, diatomite, kaolin, mica, talc, and wollastonite. Stirred ball mills (attritor mill) are much more efficient for fine grinding and regrinding than conventional tumbling mills. Conventional milling requires long retention time and tremendous energy input for micron size production. This work aims to study the parameters affecting ultra-fine grinding of Egyptian talc from Shalatin locality of the Eastern Desert to produce an ultra-finer product less than ten microns using an attritor mill in order to be used as a filler material for different industrial applications such as paints, plastics, paper coating, and other advanced applications
