Furthermore, one of the autogenous mill (AG) was converted in semi-autogenous mill (SAG) with adding 8% grinding media, appropriate lifters and liners profile, and discharge grates with 15 and 30 mm openings. The aim of the industrial experiment was to assess the benefits of SAG mill grinding, and to

High Pressure Grinding Rolls Versus Sag Mill Pitcairn. of the energy requirements of HPGR and SAG mill circuits in hard ore applications by P Rosario† and R Hall† Synopsis The application of high pressure grinding rolls HPGR has been growing in the mining industry for the last 10 to 15 years The major benefits .

Not surprisingly, some of the advantages of SAG milling are reduced in terms of increased liner wear and increased maintenance costs. Also, pre-crush can lead to an increase in mid-sized material, overloading of pebble circuits, and challenges in controlling recycle loads.

This holds great advantage for minimising relining time, as there are fewer blocks to handle. ... Mines (WA) 36ft SAG mill the number of Outer Head Liners was reduced from 36 to 18 pieces and in doing so reduced the time to replace them by 9 hours at a cost downtime saving of about U$25,000 per hour. In this case the liners sections are 3.5 t each.

Many designers and mill operators believe that the benefits of simplicity and the ability to handle throughputs in excess of 3 500 tons per hour of solids make trommels the preferred equipment for this application. "A key component ensuring optimal performance of SAG mill trommels is the screen panel, which enables this equipment to classify large volumes of mill product," says …

Advantages of SER drives for SAG mills Friday, December 19, 2014 For large mills requiring variable speed, the wound rotor motor and SER drive are economical for a total rating of approximately 2MW to 16MW. Above 16MW, the gearless drive (cyclo-converter) is typically used because gearboxes and pinion gears reach their present limit in size.

SAG mill. SAG is an acronym for semi-autogenous grinding. 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.

Based on experience, mill liner designs have moved toward more open shell lifter volumetric capacity and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. Mill throughput is maximized with shell lifters between ratios of …

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 ...
