compared to those from the ball mill circuit. This has often resulted in conclusions concerning lower energy efficiencies of AG/SAG mill circuits compared to ball mills. The correlation between the AG/SAG and ball mill circuit data is also very poor. Use of equation 2 shows a very different picture, the results being illustrated in Figure 7.

AG mills (or SAG mills with low ball charges) are often used in single-stage grinding applications. Based on their higher throughput and coarser grind relative to AG mills, it is more common for SAG mills to he used as the primary stage of grinding, followed by a second stage of milling. AG/SAG circuits producing a fine grind (particularly ...
Abstract. The lack of constraints in ball mill capacity in the published ball mill models may result in unrealistic predictions of mill throughput. This paper presents an overfilling indicator for wet overflow discharge ball mills. The overfilling indicator is based on the slurry residence time in a given mill and given operational conditions.
The SAG mill pinion energy, W SDT (kWh/t) and SAG discharge Bond ball mill work index, S d-BWI (kWh/t), are then used to calculate the total energy to grind the ore from 80% passing 152 mm to 80% passing the client specified final product size P 80.This information, along with the ore specific gravity, is used to calculate necessary mill sizes and motor power in industrial applications.
Ball-limited circuits (where the T 80 hits the lower limit) will result in the charge level in the SAG mill dropping until its power draw matches the throughput limit dictated by the ball mill. It is important to realize that once the SAG mill charge level drops to be equal to the ball charge, the model will be operating "out of range" and the ...
The plant measurements, including the observed ball mill throughput, are retrieved from the comminution circuit at the Tropicana Gold mining complex. The other dataset used in this case study to predict ball mill throughput comprises penetration rates from measurement while drilling (MWD).
mills, and use a rod mill feed size (F80) of 16,000 m and a rod mill µ product size of 1,000 m . Also note µ that in order for no correction factor for ball mill product fineness to apply, the ball mill circuit P80 should be no less than approximately 70 µm (See reference by Bond, 1962).
throughput will be lost in the ﬁne and mid-size fractions as the surface area for attrition is reduced.! Typically, SAG mill control is performed with respect to bearing pressure and other process variables which are used to estimate volumetric loading in order to optimize the mill throughput. While these
