The data provides the necessary detail to elucidate the improvements in the efficiency of energy utilisation in ball mills when using a mixture of pebbles and steel media. View Size-energyIt was found that the ball mill consumed 54.67 kWh/t energy to reduce the F 80 feed size of 722.2 µm to P 80 product size of 275.4 µm while stirred mill consumed 32.45 kWh/t of energy to produce the product size of 235.6 µm. It also showed that stirred mill produced finer product than the ball mill at around 40% lesser consumption of energy.Vertical stirred mill scale-up and simulation: Model validation by

Shi et al. (2009) carried out tests in a laboratory scale vertical mill and found the mill to be 25% to 37% more efficient than ball mills. Mazzinghy et al. (2015) performed tests with a pilot scale Vertimill and concluded that the specific selection function (energy based) is approximately 35% higher (on average) than a ball mill in a similar duty.According to Mazzinghy et al. (2015a), the parameter S1 E, obtained from the batch tests using a tube mill, shall be multiplied by a factor of 1.35 in order to get a higher efficiency of the Vertimill™, when compared to a standard ball mill. The Vertimill™ efficiency factor could be back-calculate from pilot or industrial circuits usingVertical stirred mill scale-up and simulation: Model validation by

Vertical Agitated Media Mill scale-up and simulation

The TowerMill® was developed in Japan in the 1950s, by the Tower Mill Kubota Corporation, for applications in fine and ultrafine grinding, and it was the first vertical mill used in the mineral industry (Stief et al., 1987).The Vertimill™, manufactured by TON has basically the same principle of operation and was introduced in the 1990’s (Kalra, The perfect mixing model, normally used to simulate ball mills, was used to compare the direct and reverse circuit configurations. The simulations were based on the appearance function determined from the laboratory tests using a batch tube mill. The combined breakage rate/discharge rate function () was determined from Vertimill ™ feed Vertimill™ pilot scale tests simulated by perfect mixing model
