Washing &
Screening cover story
Material then passes onto a secondary feed conveyor under a second overband magnet into the twin-shaft log washer with the blades conveying the material from the feed end of the scrub.
Any organics such as roots are floated off to be dewatered over a 1.8m x 0.6m trash screen [An angle adjustment on the log washer allows increased material retention and removal of trash].
Underflow from the trash screen is received in a catch box under the screen and then gravity fed to the sump tank under the hull. Any fines off the back end of the log washer are sent to the two rubber lined 375mm cyclones via two rubber lined 125/100 pumps. The 0-2mm, soft and 0-5mm, sharp sand are then dewatered and stockpiled.
Scrubbed aggregate then exits the main discharge of the log washer onto a 2.4m x 1.2m double-deck sizing screen which splits the required products of 10mm, 20mm and 20-50mm aggregate which are then stockpiled by 3 x 15m channel frame conveyors.
