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

Semi Autogenous Design FactorsSag Mill Operation ExampleProcess Plant DescriptionSag Mill Design and SpecificationOperating Problems Since CommissioningDesign Changes and Future Operating StrategiesThe design of large mills has become increasingly more complicated as the size has increased and there is little doubt that without sophisticated design procedures such as the use of the Finite Element method the required factors of safety would make large mills prohibitively expensive.In the past the design of small mills, up to +/- 2,5 metres diameter, was carried out using empirical formulae with relatively large factors of safety. As the diameter and length of mills increased several crit...

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.

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.

Pebble crushers also cause coarser AG product, which might be an issue depending on your downstream process. But you can't use pebble crushers in SAG circuits because the iron ore and steel balls will confuse the crusher tramp steel protection. Either fully autogenous with or without pebble crusher, or SAG without pebble crushing are valid.
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.
