SAG Mill Ball Size Evaluator | Evaluation Factors

Lets calculate/select/pick a new ball for your SAG mill. Now, lets suppose you have a SAG Mill and Ball Mill that are not drawing full kW Power. The SAG Mill has a "small" circulation load of oversize given be the 3/8″ trommel screen and the 1/2″ x 1 1/4″ discharge grates. The load of 4″ balls in this SAG is "good" but un-measured.

Semi-autogenous grinding (SAG) mill liner design and …

operation of SAG mills. SAG mills are currently the technology of choice in hard rock milling operations for reducing primary-crushed ore to ball mill feed. In recent years, the trend has been towards larger-sized SAG mills with diameters of 10.4 m (34 ft) and above, with the largest being 12.2 m (40 ft) in

Choosing a SAG Mill to Achieve Design Performance

performing SAG mill. It is possible in some cases to modify a SAG circuit to force it to perform better, but this often takes time, much effort and costly modifications. In most cases the capital spent on a properly sized SAG mill may prevent production losses that would be many times greater over the extended start up period.

[PDF] A structured approach to modelling SAG mill liner …

A numerical framework to predict the three-dimensional evolution of the liner profile within a rotating industrial SAG mill is presented. The need to understand the manner in which the lifter profile develops is emphasised by comparing two discrete element method (DEM) simulations with measured new (i.e. unworn) and worn lifter profiles. The DEM informs …

Grinding Mill Foundations

Most of our work since 2000 has been in developing grinding mill foundations to avoid vibration and unacceptable deflections. On a recent project for a plant in Peru, the client was told by the mill vendor that there was no need to do a systems (dynamic) analysis on the mill foundations because the mills on that project were gear …

Closed Circuit Grinding VS Open Circuit Grinding

An increase in the diameter of a mill gives greater economy in two ways : In the first place, the balls do more effective work in a large than in a small mill, because, falling from a greater height, they shatter the pieces of ore with greater force ; in the second place, the ratio of the deadweight of the mill to the weight of the ball charge ...
