A Method of C alculating Autogenous/ Semi-Autogenous

of the energy required by a SAG mill Put another way, the SAG mill energy required according to this statement, is 25 times more than the Ab value to produce the same degree of particle breakage There is a speci fi c gravity factor that affects AG/SAG power draw The lighter material, in …

Ball Mill Critical Speed - Mineral Processing & Metallurgy

A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell The imagery below helps explain what goes on inside a mill as speed varies Use our online formula The mill speed is typically defined as the percent of the Theoretical

GROSS POWER CALCULATOR - smctesting

AG/SAG mills in the data base are up to 40ft in diameter and ball mills are up to 26ft in diameter The measured gross power draws from these mills are plotted against the model predictions in Figure 1 As indicated by this data base the accuracy of the model (1 standard deviation) is 46%

sagdesign

The SAG mill pinion energy is determined from the SAGDesign™ testwork results as follows : W SDT = revs (16,000 + m s)) / (4473 m s) where : W SDT = AG/SAG Specific Pinion Energy from a F 80 of 1524 mm to a T 80 of 17 mm, kWh/ton ground revs = Cumulative number of SAG test mill revolutions to 80% passing 17mm m s = SAG mill feed sample mass, grams

Calculation of Sag & Tension - Circuit Globe

Calculation of Sag & Tension Calculation of sag and tension in transmission line depend on the span of the conductor Span having equal level supports is called level span, whereas when the level of the supports is not at an equal level is known as unequal level span The calculation of conductor at an equal level shown below

Calculate and Select Ball Mill Ball Size for Optimum Grinding

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do Often, the ball used in ball mills is oversize “just in case” Well, this safety factor can cost you much in recovery and/or mill liner wear and tear

Orway Mineral Consultants Canada Ltd Mississauga, ON

Barratt (1986) proposed the use of an empirical formula for predicting SAG power involving the use of a combination of Bond work indices over a range of sizes from F 80 to a defined P 80, applying a correction factor to resultant power, and deducting the ball milling component of the power; refer to Equation 2
