Optimizing your SAG mill operation International Mining Mar 21, 2007 The optimal performance of AG/SAG mills is the key to successful plant operation All AG/SAG mills using radial or curved pulp lifters suffer from inherent material transport problems such as slurry and pebble pooling, which decrease throughput and increase energy consumption The TPL completely eliminates slurry pooling and ...

Crushing in Mineral Processing

 · Since there are not that many small SAG mill operations of under 2000 TPD, and most sub-2000 TPD mills are built with rod mills and/or ball mills only; the upstream crusher plant needs to have sufficient crushing power to provide a P80 to grinding of typically <1.5″ (40 mm) and often as finely crushed as <3/8″ (9 mm).

How it Works: Crushers, Grinding Mills and Pulverizers | …

 · Crushers, grinding mills and pulverizers are types of grinding equipment that transform or reduce a coarse material such as stone, coal, or slag into a smaller, finer material. Table Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl liner.

Industrial Crushers reduce large rocks into smaller rocks, gravel, or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of ra AG/SAG

Operation of SAG Mills,Principle Operation of Semi …

Operation of SAG Mills. The processing capability of a SAG mill is greatly affected by ore geology and operating variables within the mill. The key issues broadly can be classified into two categories: field of breakage and charge motion, and flow through the grate and pulp lifters. The field of breakage and charge motion are affected primarily ...

What''s the Difference Between SAG Mill and Ball Mill

 · 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 ...

Dynamic Modeling and Simulation of SAG Mill Circuits with Pebble Crushing …

AG/SAG mill is inefficient in grinding particles of a certain size, typically in the range of 25-55 mm, i.e., pebbles. Therefore, cone crushers are often used as pebble crushers and integrated into AG/SAG mill circuits to break the critical size particles that

Autogenous and Semi-Autogenous Mills | FL

Since the early 1980s, we have been designing and manufacturing Semi-Autogenous (SAG) and Autogenous (AG) Grinding Mills under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on the ...

Power-based modelling of single-stage AG and SAG mill circuits

Operating data from the single stage SAG mill at Anglo American''s El Soldado mine in Chile was evaluated and compared to four published power-based comminution models. Case studies from literature for other single stage SAG or AG mills were then

SAG Circuit Design

SAG mill grates generally limit pebble extraction rates to around 25%, so you can''t expect a throughput increase of more than 5-10% depending on the ore. To pebble crush, you need to port the grate. This removes any fine media, so achieving a fine grind size in a single stage becomes difficult.

Redesigning SAG Mill Recycle Crusher Operation

 · Recycle crushing is used extensively to boost SAG mill throughput, by rapidly reducing the competent pebbles that would otherwise build up in a SAG mill. Although applied with considerable success, it is the Authors observation that the crushers are generally poorly utilised: operating well below installed power; switching on and off; and set at large closed side settings. Application of good ...

Optimizing your SAG mill operation

 · In multi-stage ABC/SABC circuits, the AG or SAG mills are in closed circuit with screens and pebble crushers. 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.

SAG Mill Grinding Circuit Design

 · Restated, the designed SAG mill size and operating conditions typically control circuit throughput, while the ball-mill circuit installed power controls the final grind size. Aside from parameters fixed at design (mill dimensions, installed power, and circuit type), the major variables affecting AG/SAG mill circuit performance (throughput and grind attained) include:
