A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
The bauxite sample used in a laboratory scale stirred mill and ball mill grinding tests were taken from Zonguldak Kokaksu Bauxite Mine in Turkey. Chemical composition of the bauxite sample is given in Table 1. The sample was crushed by a cone crusher below 3.35 mm and fed into both laboratory scale stirred and ball mills. d. 50
Efficient grinding, high degree of spheroidization. Higher capital investment than ultra fine grinding mill. HCH Ultra fine Grinding Mill Lower capital investment and energy consumption, it is an economic and efficient grinding mill, but lower yield on a single mill. Multiple mills will be needed for large scale production.
