RHEWUM replaces conventional gyratory screen in Australia, Melbourne
Meike Schulz, RHEWUM GmbH
To double the feed capacity of ammonium nitrate (AN) to 110 t/h the actually installed flat screen of a competitor has to be replaced.
The choice was passed to RHEWUM so to reach this high screen capacity within very small space conditions. Therefor, a conventional flat screen has to be replaced by a high performance stainless-steel screener of RHEWUM type WA(U)350x269/450/2. Screen cuts to be realized are defined to 4,0 mm and 1,0 mm. The screener has to handle product temperatures up to 118°C. Whereas the consulting, tendering and technical evaluation was arranged by WorleyParsons at Melbourne, Australia, the order processing is under responsibility of Messrs. AECOM at Perth, Australia. To fulfill customer's high quality demand the bottom deck will be excited by the approved electro-magnetic drives WA whereas the upper deck by maintenance-free drives of type WAU. To cope with labour protection directives the screen will have noise protection devices. A main reason to decide on a RHEWUM screener was, besides the construction- based reliability due to the variety of drives, that one machine half can be stopped during production for reasons of maintenance. CSBP is expecting the delivery of the screener in November 2012.
