DYNAMIC MODELLING OF A SAG MILL-PEBBLE CRUSHER CIRCUIT BY ...

In a semi-autogenous grinding (SAG) mill and pebble crusher circuit, the behaviour of the comminution process is non-linear and time-varying due to wear and variations in the feed material. To describe such a complex system, data-driven models were introduced, along with a case study of a SAG mill circuit in Copper Mountain, British Columbia, Canada.

Cone Crushers | McLanahan

A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing and reduction is determined by the closed side setting or the gap between the two crushing members at the lowest point. As the wedge or eccentric rotates to cause the compression within the chamber, the ...

Even wear in the crushing cavity avoids localized restriction of the feed opening, maintains a uniform crusher setting, and achieves consistent size reduction. The hydraulic motor and gear drive adjustment provides finer control of the setting: the setting can be easily adjusted under load to compensate for liner wear without turning off the feed.
