A vibrating screen was used to provide a mill discharge product separation at 19 mm (¾ in.). The minus 76 trail (-3 in.) plus 19 mm (+¾ in.) screen oversize product, which are the "pebbles", were then crushed to essentially minus 19 mm (-¾ in.) in a crushing circuit. This product was returned to the feed end of the mill.

The material is reclaimed via one of three vibrating feeders which deliver ore to the primary mill. The installed primary mill is an Outotec 7.30m x 3.35m effective grinding length (EGL) grate discharge SAG mill with 3.4MW installed power. The mill is also installed with Turbo Pulp Lifters (TPL) in lieu of standard radial pulp lifters.
Mill drive arrangement. Mill drives are generally located on the outside of the mill to facilitate maintenance. • Mill discharge arrangement. If the SAG and ball mills feed separate pump systems this is not an issue. If the two stages feed the same pump system, the SAG mill usually drives the discharge arrangement.
Outotec's delivery includes two ball mills and one SAG mill, all of which are based on Outotec's proprietary grinding mill technology. The largest of the …
A 4.7m x 7.5m Outotec grate discharge ball mill with an installed power of 2.6MW and Turbo Pulp Lifters is operated in closed circuit with 250mm cyclones to provide a 45 m product to flotation. The primary mill was initially commissioned as an Autogenous Grinding (AG) mill.

Grate discharge heads for ball mills are completely assembled in the shop, with grates, clamp bars, pan liners, and center discharge liners in place. Depending upon available handling facilities, the head or shell can be lined separately in a repair bay, or after assembly of the mill proper in the trunnion bearings.
We developed lifter, grate, pulp lifter and flow cavity through exit trommel model for the 40 ft Cadia mill in Australia. The study identified all wear zones, granular flow back into the mill and re-circulating flow inside the pan cavity for straight and curved lifters. At the time, we also modelled the water flow regime through the grate.
