According to the obtained results of the N-Mixer RTD model, when the ball mill throughput was enhanced from 230 t/h to 280 t/h, the MRT was decreased from 9.92 to 7.39 min, respectively. Moreover, relative variance of N-Mixer model diminished approximately 18% and particle cumulative passing from 75 μm of ball mill discharge increased 9%.
Converting a ball mill from overflow to grate discharge involves installing a grate inside the mill at the discharge end. The grate holds the balls inside the mill but allows the slurry to pass through, and it is then pumped out of the mill by the pulp lifters. This is different to an overflow mill which holds the slurry and balls inside until ...
The General Function of Ball Mills. A ball mill is a grinder used for grinding and blending materials for mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. Appearance. Ball mills have various designs and functions, ranging from laboratory-scale versions to large industrial models.
