Pebble Crushing in SAG Mill Circuit

2020-7-20  Full Scale Test Circuit Based upon the results of the pilot plant test work, a decision was made to conduct a full scale test in 1990 utilizing one of the ten (10) primary mill lines at the National Steel Pellet Plant. Primary Mill Line No. 10 would be converted to a fully autogenous grinding mill with pebble extraction and crushing. Engineering and installation of the test circuit was

Dynamic Modeling and Simulation of SAG Mill Circuits

SAG mill and its pebble crushers. The scope of this thesis is to examine the dynamic relations between the SAG mill and the pebble crusher in a closed circuit and thus to optimize the circuit efficiency by controlling the pebble crusher operational settings. In this thesis, two modeling techniques are proposed for simulating the dynamics in the

How to choose the correct pebble crusher for your site

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.Green, B.

Alamos Gold Inc., Young-Davidson Mine: Pebble

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.

Optimise your pebble crushing with HPGR

Whether recirculated through primary milling or separated and sent to a dedicated downstream pebble mill, pebble crushing is an energy-intensive operation that ties up a site’s limited resources. With their high throughput and capacity for dealing with competent ores, High Pressure Grinding Rolls (HPGR) make ideal pebble crushers.
