Oct 01, 2018  A simulation of a typical SAG-pebble crusher circuit was made to validate the hypothesis as well as to illustrate the capability of the dynamic model. The computational process was simulated with Matlab/Simulink as seen in Fig. 4. This plant has no new feed at the beginning. Fresh feed to the plant started from t = 100 min to t = 800 min with a ...

How to choose the correct pebble crusher for your site

Oct 23, 2019  The smaller the crush size, the more rapidly the pebble load will be reduced, so we recommend using a heavy, robust crusher, such as the Trio® TC series, to achieve higher throughput rates in the milling circuit. * McIvor, R. Greenwood, B. (1996). Pebble Use and Treatment at Cleveland-Cliffs’ Autogenous Mill Operations.

DYNAMIC MODELLING OF A SAG MILL-PEBBLE CRUSHER CIRCUIT

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.

Alamos Gold Inc. – Pebble Crushing Plant Halyard Inc.

Halyard designed and installed a 100TPH pebble crusher for the 9,000TPD SAG Mill Circuit. This system also has the provision for accepting pebble feed from a large historic stockpile and proportionally augmenting this with the SAG discharge.

Alamos Gold Inc., Young-Davidson Mine: Pebble Crushing ...

The SAG circuit was built without a pebble crusher and the mill was rejecting approximately 50T/hour of un-grindable pebbles. Over 5 years, 650,000 tonnes of gold bearing pebbles had been milled, rejected and stockpiled. The objective was to crush the existing 50t/hour pebble stream and to re-process the 650kT pebble stockpile.
