A preliminary investigation into the feasibility of a novel HPGRbased circuit for hard, weathered ores containing clayish material Article in Minerals Engineering 24(3):290302 · February 2011

A preliminary investigation into the feasibility of a novel HPGRbased circuit for hard, weathered ores containing clayish material. the AGCrusherHPGR circuit was designed to provide a throughput of approximately 180,000 t/d for the sample provided by the mining company. The SABC circuit was simulated using the previously developed

Weir Minerals recently sold a KHD high pressure grinding roll (HPGR) to Goldrock Mines for installation in an Argentina heap leach gold mine. After a hard fought competition by all major suppliers, Goldrock Mines awarded Weir Minerals North America an order for the supply of a roller press (RPS), or a high pressure grinding roll (HPGR) as it is known in the minerals industry.

The high pressure grinding rolls. (HPGR) is a relatively new type of equipment, very efficient in terms of energy savings. There are several configurations for comminution circuits that utilize the HPGR technology replacing either. AG / SAG grinding, or crushing/grinding stages or even as surface generation step prior to iron.

HPGR or highpressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.

This paper aims to provide a review of the modeling of high pressure grinding rolls. A Novel AGcrusherHPGR Circuit for Hard, Weathered Ores Containing Clays, in: Autogenous and Semi

layout. In an industrial appliion on hard iron ore, AG mill throughput increased by 30% by installing a HPGR in such a circuit.1 Concepts for an HPGR—ball milling circuit High pressure grinding rolls can be built with throughputs of up to 2 000 tph and more per unit. Thus one HPGR can replace several tertiary crushers at the same time HPGR.

and reduced operating cost. The Platreef appliion of HPGR also provides the opportunity to introduce a novel comminution flow sheet and to demonstrate exceptionally low wear rates treating very hard, abrasive and variable ore types. The HPGR lends itself for inclusion in existing SABC circuits to increase the capacity of the plant and mills.

sense that jaw crusher is intended for first crushing circuit while HPGR is intended for last crushing circuit. It is turns out that the optimization model of HPGR crushing process is completely di erent from that of jaw crushing process. In view of the aforementioned, this paper proposes a systems optimization model for energy management of

The HRC™ HPGR is best suited for crushing in hightonnage, hard rock appliions. Common circuits utilize high pressure grinding rolls in a number of ways: • Tertiary crusher, followed by a ball mill or VERTIMILL® • Quaternary crusher, followed by a ball mill or VERTIMILL® • In a pebble crushing circuit for a SAG/AG mill Suitable ore

Crushing and HPGR. With mineralprocessing expertise and capabilities in crushing systems, we help you design and optimize primary and multistage crushing circuits for downstream heapleach or grinding processing. We''re experienced in the design of crusherHPGR circuits, including materialhandlinganddust suppression and collection systems.

High pressure grinding rolls are an energy efficient grinding solution, and now has improved this technology even further. The HRC™, our innovative approach to HPGR technology, is like no other HPGR on the market.

The orebody contains a mixture of hard rock, softer material, and clays (sericite), in proportions that are expected to vary throughout the minelife. The feasibility of a novel comminution circuit, using an autogenous (AG) mill/scrubber and parallel trains of cone crushers and highpressure grinding rolls (HPGR) is being investigated.

A novel AGCrusherHPGR circuit for hard, weathered ores containing clays A research project was conducted at the University of British Columbia (UBC) resulting in the development and evaluation of a novel comminution circuit incorporating autogenous grinding and parallel trains of cone crushers and highpressure grinding rolls (HPGR).

HPGR may not be the right machine for less competent ore, especially when the ore has clays. So far it looks like that there are certain ore types that require too much energy to have them ground down in a conventional SAGBall Mill circuit. This is the case where HPGR circuits come handy.
