grinding media to ore ratio

grinding media filling grade of 80 volume% (mill working volume). The stirrer tip speed was set at 6 m/s and 10 m/s. Milling product and formulation A ground calcium carbonate powder from IMERYS, mean particle size of D50 = 17 μm was used as the milling product.

The control of AG mills, fed by ores with hard and soft components, can also be challenging, due to the sensitivity of the mill to the ratio of hard to soft components. In this paper, a multicomponent modelling approach was used to demonstrate that the harder component should be used as grinding media, and its use should be kept to a minimum to avoid reduction in the mill throughput.

Media Retention Grinding media is retained in the mill without the need for screens, which is why IsaMills™ can use fine media. At the end of the mill is a patented product separator consisting of a rotor and displacement body (refer to Figure 3). The close distance between the last disc and the rotor disc

 · The ratio: rotational mass flow of media to axial mass flow of ore—a concept recently introduced—has been refined and extended. It can account for similar breakage in scaled mills by the tradeoff between ore/media encounter frequency and .

flotation for a certain ore feed rate, or alternatively to maximize ore feed rate for a specific required particle size. The control strategy is shown in Figure 1. The main parameter influencing particle size from the circuit is ore feed rate. Although other factors like water addition, grinding media loading, etc. play a .

The tests involved the grinding of ore with three parameters of particle size distribution and four sets of grinding media of different sizes. Approximately 500 grams of material and 1500 grams of grinding media were used in each grinding test. Grinding times for the ore mm and 01 mm were 5, 10, 15, 20, 25 and 30 seconds;
