Optimization of mill performance by using online ball and pulp measurements In the platinum industry, by increasing the solid content in the slurry, the product becomes finer. At a higher percentage solid than 73 to 74%, the product

The oversize crusher feed size distribution, oscf, and the primary cyclone feed size distribution, pcfd, are estimated utilising the SAG mill grate size and discharge screen aperture sizes and the Rosin-Rammler size

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. ...

2018/06/17· SAG mill operation is a bit complicated because of possible fluctuations you might have in your feed size distribution or ore competency. Once calculated this can be optimised by using trajectory spreadsheet from moly-cop tools

Development of an AG/SAG mill batch test methodology Naren Vijayakumar B. Eng. (Chemical) A thesis submitted for the degree of Master of Philosophy at The University of Queensland in 2015 Sustainable Minerals Institute

The typical ROM SAG mill circuit is depicted in Figure 1. The circuit is usually closed with either a screen or, more commonly, a cyclone for product size classification. The focus of control can be divided into two parts, viz. the ...

2 o Mill feed composition control: Reconstituting the mill feed size through blending post stockpiling, will undoubtedly result in a more stable feed with an associated increase in mill throughput. 2 BACKGROUND TO MORILA 2.1

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.

Feed size and because this is a single-stage ball mill calculation, the F80 is actually the rod mill feed size 10,000 m from Table 1 and the P 80 is the ball mill circuit product. The EF5 factor only applies below 75 m to

Influence of feed size on AG/SAG mill performance

SAG mill is an investment that can produce handsome returns if extra production is needed or simply to give the mine the option to mill the hardest ores at design throughput rates. Typical tests required to define a hardness variability function, …

an AG/SAG mill (throughput, product size and power draw) is dependent on the feed composition and it could be predicted using a multi-component model. ii The new multi-component model structure (2D) was developed by iii iv ...

According to MacPherson and Turner, the optimum feed size consistent with maximum power draw is given by the relation (9.1) F 80 = 53.5 D 0.67 where F 80 = feed 80% passing size in millimetre D = inside diameter of the mill

Two new SAG milling models are developed in this work, able to predict power or specific energy consumption, including the usual design variables such as mill size; balls charge level, solids concentration in the SAG mill feed

targets by lowering the throughput. Further, the SAG mill circuit was characterized by fluctuating feed size of between x F, 80 =102 to 185 mm. A need for control of the feed size as well as blending ratios was recommended for an
