A laboratory breakage test has been developed which directly provides ore specific breakage parameters for use in secondary and tertiary crusher models and in ball mill models. The technique has been sucessfully applied to a number of actual crushing and ball mill circuit design problems.
Such mills normally have integrated classifier. This means plant design is more compact / simple in comparison to ball mill / classifier circuit. On the other hand fineness is limited. Agitated vertical mills. They have much higher specific grinding energy and from there are for production of finer products than conventional ball mills.
Ball mills represent the most widely used and functional kind of a tumbling mill. They are exceptional in terms of their ability to function in various conditions and geometries. Ball mills have been widely utilized in primary, secondary, tertiary and regrind practices for over a hundred years (Napier-Munn et al., 1996).
how many equipments are their with ball mill to run. Tertiary Ball Mill Function. efficiency increase in ball mill The ball Dry Type Ball MillWe offer many Model Predictive Control for SAG Milling in Minerals
Grinding particles below 75 µm with the ball mill causes energy costs to rise exponentially, and a P 80 of 45-40 µm is considered to be the final practical limit of product size from the ball
They will, however, in that application produce more fines and tramp oversize and will in any case necessitate installation of effective classification.If finer grinding is wanted two or three stage grinding is advisable as for instant primary rod mill with 75100 mm (34) rods, secondary ball mill with 2540 mm(11) balls and possibly tertiary
AG mills crush the ore without the need for iron or steel grinding media. They are used when the ore is hard enough for the tumbling ore to grind itself. In SAG milling, ∼0.15 m 3 of 13 cm diameter iron or steel balls are added into the mill per 0.85 m 3 of ore (i.e., 15 vol.% “steel”) to assist grinding. SAG mills are much more common.

The fine fraction serves as a feedstock for the tertiary comminution stage, which employs ball mills, while the oversize fraction is returned to the HPGRs. In the example of Vale‘s Solobo Mine, the material classification is performed by hydrocyclones (Fig. 15) after the tertiary milling and before feeding to the flotation stages.
SAG mills • Determination of your SAG mill’s power draw characteristics. • SAG Mill Steel Charge Estimation tool provides an estimate of the percent steel in the charge of your SAG mill based on the power draw and the total charge volume. • Ball impact energy chart to determine the impact energy of balls as a function of mill diameters.
The mine’s original grinding circuit consisted of ball mills exclusively. Due to downturn in the iron & steel industry, Miaogou’s concentration costs were exceeding the price of iron concentrate, putting significant pressure on company’s operations. The original tertiary grinding fineness was -325 mesh with 71-73% passing.
