Increase throughput and capacity in SAG mills

SAG mills are the main workhorses in the majority of comminution circuits globally. They need to be fed and kept working round the clock. But challenges can arise when capacity is not optimised causing unnecessary downtime and liner wear leading to the one sound operators do not want to hearthe sound of the mills standing still.

Estimation of pulp viscosity and grinding mill performance

It is well known that the density and viscosity of a mill pulp have optimum levels for grinding efficiency and sophisticated control loops are employed to control pulp density in industry. However these control loops rely on a number of plant measurements and often the input data will not permit effective determination and control of the mill pulp density.
