Jul 05, 2020· 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.


The power draw for the simulated ball mill (5700 kW) is close to its rated motor power (6000 kW), however, greater than the power draw for the actual mill (5268 kW). The increase in power draw is due to an increase in ball volume from 24% v / v (actual) to 27% v / v (simulated).

The motor power draw required to turn a mill from rest to the operating speed includes the energy required for the initial starting torque and mechanical arrangements to rotate the mill. It is generally accepted that practical mill power (PM ) is a function of mill capacity and diameter, i.e.,P M = Mill Constant * (Mill Diameter ) n


The ball mill is powered by a fairly robust 12V DC motor salvaged from a junked printer. It had a pulley for a fine-toothed belt on it. It was left in place and it seems to drive the heavy round rubber belt well without slipping. The motor was mounted using screws on only one side, which were deliberately left loose.


These have also been employed in gearless cement mill or ball mill drives. Reduced Voltage Starting (Soft Start): The starting line current at full voltage of an induction motor may be about 6 times the rated full-load current. Such a high current may cause severe voltage dip in the network supplying the induction motor.

Ball mill - Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
