 · AG Mill,SAG Mill_CITIC HICCITIC HMCCITICIC. CITICIC can produce below 12m autogenous mills and semiautogenous mills, China CITICIC SAG/AG mills range in size, feed size to this mill is limited.

the SAG mill critical speed; Pc = SAG mill power consumption (kW); % 600 +100 = % of the fresh feed in the size range 152 +25 mm. M. Silva, A. Casali/Minerals Engineering 70 (2015) 156–161 157 In fact the later can be modelled as a function of the others.

SAG mill feeds. The benefit is that it allows the mill to process a greater throughput of ore than with a typical feed size; however, high throughput means that small changes in ore properties can cause big changes in mill loading to happen very quickly. Fortunately, with BrainWave monitoring mill load, changes in feed properties are recog

F = Feed size, 80% passing (µm) f(x j) = (+x j/) In 2011, Morrell discussed the appropriateness of SAG mill transfer size in regards to grinding mill specific energy modelling. It was suggested that since AG/SAG mills are mostly operated in very near 274

The throughput capacity and efficiency of a SAG mill are affected by the significant recirculated load derived from oversize discharge product (critical size "pebble" discharge) that is screened out and may be stockpiled or requires secondary crushing prior to reintroduction to the SAG mill feed. Where the SAG mill/ball mill circuit is the bottleneck in the processing plant the pebble ...

MinetoMill: Changing AG/SAG feed size through blasting Professional development and learning material for minerals processing engineers. In this last presentation different ways of changing DrillandBlast design and how DrillandBlast is implemented to effect changes in Rom distribution are explored. Contact . Modelling SAG milling power and specific energy. .

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 125 mm) High capacity (short retention time) Less sensitive to feed composition (critical size material) [PDF]

respect with SAG mills being increasingly less sensitive as the ball charge is increased (Morrel S and Valery W, 2001). EFFECT OF FEED SIZE DISTRIBUTION ON SAG MILLING The qualitative effect of changes in particle size distributions (PSD) on the SAG mill performance can be addressed by using the grind curves. The operation of SAG mills is

Outotec Premier™ horizontal grinding mills are supported by the use of advanced simulation tools during the design phase. Our tools use 3D technology and evaluate all parameters of the mill design. Ranging from the mill body, to the open gearing to the bearing system. These advanced simulation tools provide a comprehensive view to not ...

The feed size for these mills is limited to the maximum size that can be practically conveyed and introduced into the large mill feed chutes. And the product of the large AG/SAG grinding is either a finished size ready of processing, or an immediate size for further grinding in a ball mill, pebble mill, or a VERTIMILL® or a stirred media ...

Jan 01, 2015 In Fig. 3, Fig. 4 the data is presented in order to show the effect of the fresh feed size, particularly the % −6″ +1″ (−152 +25 mm), on the SAG mill power consumption (Pc) in kW and on the SAG mill specific energy consumption (Ecs) in kW h/t, obtained by dividing the power consumed (kW) by the fresh feed rate (t/h)

Manual sampling of the process streams such as AG/SAG mill feed, trommel screen undersize product ( + mm), ball mill discharge and cyclone feed, overflow and underflow have been conducted in order to characterize the particle size distribution in the products and to carry out mass balancing of grinding circuits.

The 2 nd stage of the test measures the Bond Ball Mill Work Index on SAG ground ore, S d BWI. SAGDesign ore feed is prepared from a minimum of 10 kg of split or whole diamond drill core pieces or run of mine ore, by stage crushing the ore in a jaw crusher to 80% passing 19 mm.

SAG is an acronym for SemiAutogenous Grinding. SAG mills are autogenous mills but 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' () in diameter, powered by a 28 MW (38,000 HP) motor.

Ø Effect of SAG Mill Feed Size Distribution and Ore ... SAG Mill Speed The design operating speed of the SAG mill was 74% of critical speed (). Operating at this speed during commissioning led to ball breakage due to overthrow of the charge, resulting in direct balltoliner impacts. The initial set of SAG mill shell liners were a 78 ...
