The plant consists of a 25 tonne live capacity hopper with a Rocktec F250B vibrating feeder which feeds material via conveyors to either the Rocktec vertical shaft impact (VSI) crusher, or a Dry PAP screen.
From the VSI material is delivered to the Rocktec Avalanche 6000 x 4200 double deck extra heavy duty dry PAP screen via a conveyor. The crushed aggregate is then delivered to a pair of Rocktec Avalanche screens for washing and grading, 4200x1500 and a 3600x1500 Triple Deck Extra Heavy Duty screen. The wash water is transferred to the Rocktec 16’ Screw Dewaterer, were the fines are removed from the water. The products are stockpiled in six concrete bunkers. This tertiary plant has been designed and tested to process up to 200 tonne an hour.
Rocktec designed and built the body of the VSI crusher to use standard OEM rotor and shaft line assemblies. It features an air transfer system to control dust, improved rotor access and two 150kW WEG motors.
“This prototype has been built on known parameters and we had no issues whatsoever with the commissioning – everything with the first inspection was as predicted.” said Jason Tapper, Rocktec’s Sales and Marketing Manager.
“We are very happy with the finished plant at Drury” said Jason Tapper.
