Pebble Crushing in SAG Mill Circuit 911metallurgist

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.

Optimise your pebble crushing with HPGR The Weir Group

2019-09-05· One thing to note when deploying a HPGR in a pebble crushing circuit is that truncated feed (one with a narrow size distribution) may cause higher wear on the surface of the machine’s rollers than encountered in other applications, as the more “mobile” particles generate a weaker autogenous wear layer where the coarse pebble fragments

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.
