The size analysis of a gold bearing ore crushed in a jaw crusher indicated that 80% passed through a 3000 micron sieve. Further size reduction was completed in a 1.0 xx1.5m wet ball mill rotating at 78 % of the critical speed to liberate the gold. Determine the maximum size of the balls at the ommencement of grinding. Data: S.G. of the ore =3.86.

 — In some plants a ball-mill or rod-mill will reduce the ore to, say, 100 mesh and a tube-mill will finish the grinding to 200 mesh or finer. In other plants a ball- mill or a tube-mill will do all the grinding, but it must be fed with fine ore—say, 1/8 to ¼ inch—to do this properly. Grinding coarse ore in a ball-mill is done by steel balls ...

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 drum length to diameter ratio greater than 1.5 are referred to as tube mills.

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.

A dynamic model is developed for a wet overflow ball mill based on a set of mass and energy balances to simulate the mill. The energy balance relies on temperature and mass flow data. The key control parameters to be measured are mill temperature (feed and discharge streams), mill power draw and the mass flow rate in the feed stream.
