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 grinding process. The first method is the fundamental modeling method, where the underlying

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.

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.

Base Case example: 34' x 13.3' SAG Mill and 22' x 36.2' ball mill, with pebble crusher, under regular operating conditions. Between -10% and -30% based on W SDT. Transfer Size T80: The T80 value is usually 1/3 of the smallest aperture if T80 is unkown. Pebble Crusher Factor: This is suggested value but can be changed as required. Reduction Factor:

Halyard designed and installed a 100TPH pebble crusher for the 9,000TPD SAG Mill Circuit. This system also has the provision for accepting pebble feed from a large historic stockpile and proportionally augmenting this with the SAG discharge. The HP200 operates on a Variable Speed Drive to account for varying feed conditions.

The pebble crusher was reduced in size and the pebble bin capacity was increased to allow for a more consistent flow into the pebble crusher. Uncrushed pebbles were returned directly to the SAG mill, bypassing the pebble crusher, to further improve circuit efficiency.

The hypothesis put forward in this paper is that active control of the cone crusher's eccentric speed and closed side setting (CSS) can increase throughput and/or energy efficiency of the SAG circuit. To verify this hypothesis, a dynamic model of a SAG mill-pebble crusher circuit was implemented.

the SAG mill and ball mill was 8658 kW, which caused partial over-grinding. From experience in processing plants outside of China, the power rating of the ball mill should be higher than that of the SAG mill [5]. The pebble crusher had an over-powered configuration. The installed power draw of 630 kW

b) Semi autogenous grinding in which the pebble fraction of mill discharge (+½ in.) is taken out through pebble ports for separate crushing and ball milling. The minus ½ in. fraction of mill discharge is recycled to the SAG mill through a classifier. The circuit is called SACB: Semi autogenous/ Crusher/Ball mill.

For tumbling mills the 2 indices relate to "coarse" and "fine" ore properties plus an efficiency factor which represents the influence of a pebble crusher in AG/SAG mill circuits. "Coarse" in this case is defined as spanning the size range from a P80 of 750

Pebble Crusher Installation. Client: Sandfire Resources NL. ... CPC Project Design was engaged by Sandfire Resources for the fabrication and site construction of a pebble crushing circuit to process SAG mill oversize material. The scope of work included:

SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
