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 ball mill is the best choice when long term, stationary milling is justified by an operation. Sold individually or as part of our turn-key ...

One of the primary differences between a SAG mill and other types of mills, such as ball mills or rod mills, lies in the way they break down the ore. In a SAG mill, the ore is crushed and ground by the impact of the ore itself and the grinding media. This autogenous grinding process allows for a more efficient and cost-effective method of ore ...

The ball mill is usually the largest energy consumer at a mine site and significantly affects operational expenditures. Given a target particle size, Bond Mill Work Index estimates are used to predict a ball mill's throughput. In order to maximize ball mill throughput and optimize energy utilization, it is important to get these estimates right.

The size of 30 mm was optimum for raw materials of −0.45 + 0.15 mm and −0.15 mm. The optimal ball size distribution was 12 mm (40%), 20 mm (40%), 32 mm (10%), and 40 mm (10%) for dry fine-grinding of calcite ore. Finer ball loads were unable to break coarser particles nipped in the feed.

Typical types of mill used in ore beneficiation are autogenous (AG) and semi-autogenous (SAG) mills together with ball mills to, for example, obtain particle sizes smaller than 100 µm. One process variation that has become increasingly established in recent years is the combination of AG or SAG mill with a ball mill and a downstream agitated ...

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

During the running-in process, the amount of steel balls is added for the first time, which accounts for 80% of the maximum ball load of the ball mill. Steel ball sizes are Φ120㎜, Φ100㎜, Φ80㎜, Φ60㎜, Φ40㎜. For example, the 100-150 tons ball mill has a maximum ball loading capacity of 9.5-10 tons. For the first time, 30% – 40% of ...

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. 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.
