The feed size of an ore to a 1.7 m×1.7 m wet ball mill operating in closed circuit was 5000 mm. The work index of the ore was determined under dry open circuit conditions and found to be 13.5 kWh/t. The mill bed was filled to 30% of its volume with balls of density 7.9t/m3. A 20:1 reduction ratio of ore was desired. The mill was operated at 80 ...
3. The ball mill is of good quality. The better the quality of the ball mill, the more stable the performance of the ball mill will be during operation. In addition, as for the lining plate of the ball mill's wearing parts, the quality of the lining plate affects the overall production efficiency of the ball mill. As we all know, the lining ...

The model demonstrated to be able to predict non-linear rates in grinding coarse particles in ball mills [20], predict the effect of operating and design variables on breakage rates in ball mills [21], as well as vertical stirred mills [[22], [23], [24]]. The mechanistic UFRJ mill model is based on the combination of DEM that is used to ...
The laboratory scale ball mill specifications and the experimental conditions employed in the test runs are shown in Table 2.The mill speed was set at 104 rpm corresponding to about 75% of the critical speed.The 1.86 kg ball mix (15, 20 and 25 mm) was used in the mass ratio of 4:3:3, resulting in a 40% filling rate (J) of the mill valid …
Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a …
The ball mill is a tumbling mill that uses steel balls as grinding media. Ball mills can be used in wet or dry systems for bulk and continuous milling, and are most widely used in …
The ball mill grindability test at 65 mesh showed 12 kWh / t. The internal diameter of the ball mill was 5.03 m and the length to diameter ratio 0.77 . The steel balls occupied 18% of the mill. The total load occupied 45% of the mill volume. If the mill operated at 72% of the critical speed, determine the mill capacity (t/h).
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a …
The mill was expected to produce a product of 80% passing 150 microns. The feed rate to the mill was 300 t/h. The ball mill grindability test at 65 mesh showed 12 kWh/t. The internal diameter of the ball mill was 5.03 m and the length to diameter ratio 0.77. The steel balls occupied 18 % of the mill. The total load occupied 45% of the mill volume.

At Carajas, the new grinding plant was operational in 2002, with two ball mill lines followed by a de-sliming plant. The closed circuit, wet grinding mills were designed to operate at 600% circulating load, in order to minimize the production of fine particles and consequently give increased recovery at the de-sliming plant.
