Oct 12, 2017· SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.

A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft.As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam.
Iron ore grinding is completed in the ball mill, so the Iron ore ball mill is the main place for ore materials. Just like other ball mills, the Iron ore ball mill is mainly composed by a feeding part, an exhaust end, a rotation, and transmission part(a reduction box, an electrical machine, an electronic control, and pinion drive gear) and other ...

influences the grinding efficiency. In iron ore, for instance, a variation of 2 to 3% solid content in the slurry could lead to a difference up to 10% on the energy (kWh/T) for a similar grind. Optimization of mill performance by using online ball and pulp measurements J o u r n a l P a p e r
The benchmark circuit varies with plant capacity and ore competency: • 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. • .
is added to assist in size reduction. This is known as a Semi-Autogeneous (SAG) mill. AG mills bring about size reduction by a combination of impact, attrition and abrasion forces. The ore is swept up one side of the mill and at a certain point it falls back to impact the toe of the charge at the bottom of the mill.

mills in the older plants that had many mills in parallel. In fact this is generally still the case in the multi-stream plants, where mill liner design and selection is only tackled on a cost consumables basis. However, the gains to be had through good liner design and selection are just as great as on the large SAG mills.
In the past, when primary, secondary and tertiary crushers fed material directly to large ball mills, the energy efficiency of the concentrator was determined for the most part by the ball mill operation, whereas now the energy efficiency of a plant often rests largely on the SAG mill operation.

Iron 3 SAG mill (8 – 15% ball charge) Variable or moderate competency ore
SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the mill.
The conveyor carrying crushed ore from the mine to the concentrator area is 2.4m wide and 1.7km long. The largest AG mills in the world, they're 12.2m in diameter and 11m long with 28MW gearless motors. The ball mills, the second stage grinding equipment, are 7.9m in diameter and 13.6m long, each with two 7800 kW motors.
