Most mills used in mining rely on impact to breakdown rock to a suitable size for downstream processing. The impact can be rock on rock such as in an Autogenous Grinding (AG) mill, rock and a small ball charge (~10%), used in Semi Autogenous Grind...

The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol ...

The SAG mill had a 6–8% ball charge and the power consumption was 8 kWh/t, which agreed well with the expected value. Problems. In an SAG mill the dimensions of the mill were m × m and the specific gravities of the mineral and that of the balls charged were and, respectively.

It is important to note that the Bond Ball Mill Work Index on SAG ground ore is similar to but not the same as a crushed Bond Ball Mill Work Index. It is ~ 7% higher because the SAG mill grinds the softest components quickly and leaves the harder material to be ground in the ball mill. Figure 3 presents the graph of SAG pinion energy vs. BWi.

intermediate size ready for final grinding in a ball mill, pebble mill, or VERTIMILLTM. Wet grinding is accomplished in a slurry of 50 to 80 percent solids. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

Dec 21, 2016· 2 parallel SAG Mills each feeding 2 parallel Ball Mills (4 total). Around 50,000 TPD total grinding circuit capacity.

• Single stage crush/single stage SAG mills and two stage crush/ball mill circuits are typically selected for low throughput plants (<50 t/h) where personnel costs are a large component of costs. • SAB circuits are typically selected for plants of to 2 Mt/a.

Attrition mill is a type of grinding mill by kinds of media to crush lump to powderlike substances. The impact can be rock on rock such as in an Autogenous Grinding (AG) mill, rock and a small ball charge (~10%), used in Semi Autogenous Grinding (SAG) mills, balls of various sizes in Ball Mills and less commonly these days, steel rods in Rod Mills.

ball mill can be reorganised as [7] and [8], where B''Wio and A''Wio are the corrected operating work indices and WAG/SAG, WBM are the respective power draw of AG/SAG and ball mills. Note that the ball mill operating work index is applied only on the portion that needs the additional grinding (Q2), which renders to the AG/SAG mill the
