    Influences of operating parameters on dry ball mill ...

    parameters such as mill speed, ball filling ratio, ball size distribution, powder filling ratio, grinding aid dosage and grinding time were studied. The results of grinding tests were evaluated based on the product particle size (d 50, d 80) and surface area (m2/kg). As a result of this study, optimum grinding test conditions determined to be 70% of Nc, J= for ball filling ratio, 40 mm (10 ...

  • Factors Affecting Ball Mill Grinding Efficiency

    Factors Affecting Ball Mill Grinding Efficiency

     · a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different length to diameter ratios for a given power rating will yield different material retention times, the longer units being utilized for ...

  • Ball mill

    Ball mill

    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. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the ...
