The Rotor Scoop is widely used for separating the different grinds of ore.
The bushes operate in a dirty, wet environment at ±3 RPM. Previously phosphor bronze bushes were used which had
limited wear life.
Two large Vesconite bushes, one with outside diameter 177 mm (6.97"), inside diameter 152 mm (5.98") and 279 mm
(10.98") long and the second with outside diameter 177 mm (6.97") , inside diameter 152 mm (5.98")and 151 mm
(5.94") long were fitted instead. This greatly extended the operating life of the scoops with less maintenance
