    Semi Autogenous Design FactorsSag Mill Operation ExampleProcess Plant DescriptionSag Mill Design and SpecificationOperating Problems Since CommissioningDesign Changes and Future Operating StrategiesThe design of large mills has become increasingly more complicated as the size has increased and there is little doubt that without sophisticated design procedures such as the use of the Finite Element method the required factors of safety would make large mills prohibitively expensive.In the past the design of small mills, up to +/- 2,5 metres diameter, was carried out using empirical formulae with relatively large factors of safety. As the diameter and length of mills increased several crit...

  • Grate-Pulp Lifter Interaction in SAG/AG Mills - AusIMM

    It is based on: an appreciation of the process interaction between grates and pulp lifters, an interpretation of mill charge structure as it relates to discharge through grates, and an analysis of pulp and solids flow in pulp lifter channels. This approach can be used to improve the overall discharge effectiveness of AG and SAG mills.

  • SAG mills (semi-autogenous grinding mills) - Metso

    SAG milling extends itself to many applications due to the range of mill sizes available. They 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 done by a ball mill. SAG mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult, if not impossible. Efficiency ...

    Feed ore with a top size of up to 200 mm (8 in.) and water enter the feed end of a SAG mill through a feed chute; the ore is milled in the shell and milled product exits through grates and pulp lifters at the discharge end (Fig. 1).

  • Optimizing your SAG mill operation - International Mining

    The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal. In addition, operating mills at ...

  • SAG Mill - Semi-Autogenous Grinding Mill

    A SAG mill is characterized by its large diameter and short length. It rotates, tumbling its contents violently , causing a breaking action. The mill is lined with wear resistant steel liners which are fitted with lifters to assist with raising the load. The liners are replaced as they wear and the lifting action has degraded. The load - dry ore, steel balls and water - occupies approximately ...

  • Mill (grinding) - Wikipedia

    SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. A SAG mill with a 44' (13.4m) diameter and a power of 35 MW (47,000 HP) has been designed.

  • Autogenous and Semi-Autogenous Mills - ScienceDirect

    A variety of grates with varying patterns, numbers and sizes are used. Some grates have tapered holes. The main idea is to prevent the build-up of middlings inside the mill, which after a period of operation tends to build up and inhibit production rate. The dry autogenous Aerofall mills do not have any gratings. They are swept with an air draft. The draft carries and discharges grounded ...
