Dec 31 1995 A comparison of energy requirements and rheological properties has been carried out for grinding of coalwater slurries produced in high-speed stirred and conventional ball mills. In each case a linear population balance model using specific energy input as a reduced time variable resulted in a satisfactory description of the size distributions.
Ball mills are used in a wide-range of industrial applications cement processing paint dyes and pigmentation processing coal and ore processing chemical processing and pyrotechnics and many others. Ball milling has several key advantages over other systems cost of the grinding medium and installation is generally low
