Ball Mills
Ball and pebble mills are usually operated at 70—85 % of critical speed. For dry grinding the speed is usually somewhat lower. Critical speed graph. Example : A mill with 4.5 m dia (15′) N obtained = 20 rpm. If N = 15 rpm nc obtained = 75 %. Ball Mill Lining

Ball mill
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

Benefits of Dynamic Process Simulation for Mineral Industry
pebbles from the SAG mill are sent to a screen and then a pebble crusher. The crusher discharge and the product from the SAG mill are collected in a sump box where they are mixed with additional water. The slurry is pumped to a battery of hydrocyclones, the rejects of which are sent to a ball mill which recycles the ore to the sump box.

Addition of pebbles to a ball-mill to improve grinding efficiency
However, continuous pilot-plant tests were disappointing, because the consumption of small pebbles was too high. The idea of using a mixture of balls and pebbles, at a mill speed suitable for ball-milling, was revisited in this investigation, using a normal spectrum of pebble sizes (19-75 µm).

The plant has been in operation since 2015. The challenge Pebble crushing is considered one of the hardest crushing applications as the “pebbles” are very hard, with a Crushing Work Index (CWI) up to high 20s. Additionally, the crusher is run at very tight closed side settings, sometimes down to 8mm to help increase the ball mill throughput.

Addition of pebbles to a ball-mill to improve grinding efficiency
Pebble-milling is used on some mines for secondary grinding, to reduce operating costs. However, the availability of pebbles is essential and pebble storage is required. The pebble mills need to be much larger than ball mills, to draw the same power, and hence it is not easy to change from one type of milling to the other.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill’s
