Mill Sizing: After laboratory and pilot plant testing confirm the feasibility of autogenous or semi-autogenous grinding, it can be used to establish the exact grinding circuit and mill size.In the pilot plant tests, the tare power of the pilot plant mills should be determined before and after each test run. The tare power should be for the empty mill.

The capacity of the SAG mill is related to lots of factors such as feed size, size distribution, discharge size and grindability, etc., and it should be confirmed according to the actual situation. SM40*14'——means it is a dry mill.

By combining with SAG discharge and screening on the SAG discharge screens, top size control to the ball-mill circuit feed is maintained while still unloading the SAG circuit (Mosher et al, 2006). A variant of this method is to direct pebble-crushing circuit product to the ball-mill sump for secondary milling: while convenient, this has the ...

– Autogenous (AG) mills – Semi-autogenous (SAG) mills. For finer size ranges (20mm > P80 > 30 μm): – Ball mills – Vertical roller mills – Hammer mills – Roller press or high compression roller mills – Vibration mills – Jet mills. For yet finer grind sizes (sometimes referred to as "ultrafine grinding"), specialist mills are used.

SAG mills of comparable size but containing say 10% ball charge (in addition to the rocks), normally operate between 70 to 75% of the critical speed. ... For smaller plant in the 1980s, these ores were treated through a single-stage SAG mill grinding to 75 or 106 ... If the SAG and ball mills feed separate pump systems this is not an issue. If ...

AG/SAG Mill Liners Shapes. The shape of the AG/SAG mill liners include: Flat liner. For fine grinding silo, the rising height of the grinding body depends on the static friction coefficient between the lining plates. Bead liner. Used in the first bin, it can make the grinding body rise higher and have larger impact energy. Convex ribbed liner.

grinding mill sensitivity swissclassic2017ch. 31/12/2020 Sensitive to feed composition (critical size material) SemiAutogenous Grinding (SAG) Mill Wet or dry; Higher capacity than AG mill grinding; Primary, coarse grinding (up to 400 mm feed size) Grinding media is grinding feed plus 412% ball charge (ball dia100 125 mm) High capacity (short retention time) Less sensitive to feed composition ...

The power draw of the SAG mill has room for significant improvement. As ball filling in the SAG mill is quite low, additional grinding media would likely increase the processing capacity of the SAG mill; however, the capacity of the ball mill, with installed power for the required product size of 170 µm, has reached its limit.

Our market share in China exceeds 80% with the largest mills supplied to date being a Ø7.9m x 13.6m 2x8.5MW Ball Mill and a Ø11m x 5.4m 2x8.5MW SAG Mill, being the largest in China. ZTIC SAG/AG mills range in size below 12m diameter .

Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.

Jan 01, 2013 Before the ore is processed by the SAG, its size is analyzed by a Wipfrag camera that provides a granulometry estimate. A cone crusher reduces the SAGs discharge screens oversize material. A 14 foot diameter ball mill ensures final grinding before the flotation stage.Many control strategies were used at the SAG over the past few years.

Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.

The feed size is usually between 20-30mm and the product size is 0-3mm. Feed. Both the autogenous grinding mill and the ball mill feed parts are welded with groove and embedded inner wear-resistant lining plate. As the sag mill does not contain grinding medium, the abrasion and impact on the equipment are relatively small.

The semi-autogenous mill is also called SAG mill which is an acronym for semi-autogenous grinding. It is similar to an autogenous mill but uses grinding media like a ball mill grinder. It takes material itself as the main grinding media and grinds through their mutual collision. However, some raw materials with a diameter greater than 20mm and ...
