A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. 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. ...
is currently the gearless mill drive (GMD). In GMD systems the motor's poles are directly installed on a pole flange on the mill shell, and the body of the mill itself becomes the rotor. Ring-geared mill drive For mills with standard diameters or requiring less than 20 MW (approx.) of power, ring-geared mill drives (RMDs) offer the best solution.
ball-on-shell impacts just above the charge toe, owing to the risk of ball-on-liner damage and excessive metal flow. In fixed-speed mills, this may be achieved by increasing charge volume; in variable speed mills, this may be achieved by reducing mill speed; and in both cases this may be achieved by design by increasing the lifter face angle.
