Control SAG Mill sound detection

Where I work now, Minera San Cristobal in Bolivia, we use sound control on both the SAG and Ball Mills The result of this control is a 25% increase in throughput, over the plant design, with a 10% reduction in energy consumption; the mill is more efficient...

control grinding mill with sound

Grinding Mill Control Grinding & Classification Circuits Having used weight control and power draw to control Mill operations, using Mill Sound to run a mill was a new one for me I found it unusual and not that effectiveHas anyone else used that style of operation control to run their mill and did you find it more effective than the more ....

Optimizing your SAG mill operation

Similar to the impeller design affecting pump capacity, the pulp lifter design affects the discharge capacity (or mill throughput) of AG and SAG grinding mills Generally, the discharge from AG/SAG mills consists of one or both of the following components: slurry (water and finer particles) and pebbles (20-100 mm)...

Mill (grinding)

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 ,...

Grinding Mill Control

In one 36 ft SAG we used load cells for weight control (to adjust speed), with feed rate control and power control were used in conduction with the speed control Worked excellent There was an AMIRA project to develop some instrumentation to analyse sound generated by the operation of mills and use it for mill control...

MEI Blog: Where are SAG mills going?

Aug 25, 2014· I do think that the day of the SAG is done The "size" (volume) goes up as the square of the diameter, but the energy intensity (gravity*height) goes up only linearly as a function of diameter Thus, to double the impact from where we are now you need an 80 foot 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' (128m) in diameter, powered by a 28 MW (38,000 HP) motor...

Overload Detection in Semi

Detecting the onset of overloading in a semi-autogenous grinding (SAG) mill is a challenging task for operators to perform due to the complex and nonlinear nature of an overload To detect an overload, operators must simultaneously monitor the correlations between several measurements of the SAG ,...
