Pebble Crushing in SAG Mill Circuit

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

Dynamic modeling and simulation of a SAG mill-pebble

Oct 01, 2018· The first graph shows that the throughput of the SAG mills is affected by the pebble crusher settings. A cone crusher with settings like CSS = 28 [mm] and speed = 280 [rpm] gives coarser product than a cone crusher with smaller CSS and higher eccentric speed. The crusher’s capacity with a larger CSS and lower speed is higher than with a small

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.

Gold plant pebble crushing Henan Deya Machinery Co., Ltd.

Dec 17, 2020· The need for pebble crushing stems from two factors: a depression in SAG grinding rates at certain particle sizes, and the accumulation of a harder fraction in the mill load. These factors typically result in a mill throughput increase with the installation of pebble crushing that is larger than would be expected purely on the basis of the

INVESTIGATION OF SORTING TECHNOLOGY TO REMOVE

In addition to the mill volume reduction, the critical size material is harder than the normal material and this contributes to additional power draw. In order to overcome the effects of pebbles in the circuit, it is common to install pebble crushers in an AG/SAG circuit. This has increased the AG/SAG mills capacity in some cases by up to 25%
