Read more...Mill feed particle size is significant for AG/SAG load management. Monitoring of the feed to the mill by image analysis, for example, provides a measure of the particle size distribution (Chapter 4). Felsher et al. (2015) describe stabilization of SAG power draw by adjusting apron feeder ratios to target higher fines fraction in the SAG feed.

Read more...The high power intensity results in a small mill with short residence times – less than a minute – which avoids overgrinding. This, together with the 8 consecutive stages of grinding and product separator, produces a sharp size distribution without external classification.
