Mill (grinding) - Wikipedia. The specific surface area referring to volume S v and the specific surface . F 80 is the mill circuit feed size . and can be used after ball mills in a grinding .
The balls can be in a different diameter that occupies 30-50% of the mill volume and the size depends on the mill size and feed. The big balls eventually tend to break the coarse materials and small balls help to form a perfect product that reduces unnecessary spaces between balls. Ball mills grind the material by attrition and impact.
The experimental mill used was a laboratory size of 209 mm diameter, 175 mm length, providing a total mill volume of 6001 cm3, with a total mass of 5.6 kg of steel balls of 46, 26 and 12.8 mm ...
