Sep 05, 2019 · First, a quick overview of why a dedicated pebble crushing circuit is so important. The challenges of pebble crushing Ranging in size from 25-90mm, pebbles are oversized material produced from autogenous and semi-autogenous grinding, which are too coarse to be crushed by larger lumps of ore and steel balls and too fine to act as grinding media themselves.

pebble crusher circuit -

Pebble crusher is always used with SAG mills in metal ore crushing and processing in a recirculation circuit. Usually, cone crusher, impact crusher play the role as pebble crusher in gold ore crushing, copper ore crushing, iron ore crushing and so on.

Optimizing Performance of SABC Comminution Circuit of the ...

The pebble crusher had an over-powered configuration. The installed power draw of 630 kW (actual power draw of 213.5 kW) is over-sized and therefore had a low operation efficiency. The crusher remains operational intermittently, which means it is not possible to continuously Figure 1. Wushan Phase I SABC circuit layout and equipment specifications.

SABC Grinding Circuit Operation & Optimization

When operating a grinding circuit (at Granny Smith) under a wide range of conditions: campaigning very competent underground ore followed by soft oxide, primary versus secondary crushed feed and finally single-stage SAG and conventional SAG, ball mill and pebble crusher (SABC) configurations. Economics changed and a review of the circuit performance including modelling and simulation resulted in the circuit …


OMC have been assisting an African gold mine in optimising the comminution circuit, with a focus on operations practices and plant utilisation. The original circuit configuration consisted of a primary crusher followed by a SAG mill with a pebble crusher and a ball mill (SABC).


The circuit consists of a 34’ x 20’ EGL SAG mill, a Raptor 900 pebble crusher and two 24’ x 39’6” ball mills. Each mill is equipped with a 2 x 8500HP dual pinion drive system. The plant was designed to process 1585 h mtpof SAG feed. From startup, the mill struggled to meet the required production rates.

A semi-autogenous (SAG) or autogenous mills (AG) circuit commonly comprises a pebble (cone) crusher to deal with the critical size particles. The pebbles crusher is often oversized, and thus not fully utilized.

How to choose the correct pebble crusher for your site

Oct 23, 2019 · To sum up, the most important factors in selecting a pebble crusher are its ability to operate at tight settings and to withstand regular and significant tramp events. 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.


As a rule of thumb this value can be estimated by assuming that it is 0.75 of the nominal pebble port aperture (in this case the pebble port aperture is 70mm). The pebble crusher is set to give a product P80 of 12mm. The pebble crusher feed rate is expected to be 25% of new feed tph.
