Learn More· In the presented paper attention is paid to the ball mills, semi-autogenous and autogenous mills. The applications of mills are reviewed. The most used working regime of ball mills is described. The factors, affecting the milling process are examined.
Learn More· The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
