iBulk Solutions Pty Ltd installed three gyratory screeners to handle the grading and screening requirements at the Yarraville Sugar Terminal in Melbourne.

Bilfinger Berger Services sought a suitable screening solution during the rebuilding of the Yarraville Sugar Terminal to screen 120tph of sugar into the requirement of graded and caster sugar.

iBulk Solutions managing director Tony Webber said that the seemingly simple requirement took about two years of development prior to the order placement with the company working closely with several consulting engineers who were specifying the machinery for the plant upgrade.

Having worked on many similar installations at a number of local sugar refineries, iBulk drew on their broad range of experience to correctly specify the right machinery for the job. Their long association with Rotex also enabled them to access additional research data from installations around the globe.

After considering all the options, it was decided to install three iBulk Rotex 70 Series gyratory screeners to handle the grading and screening requirements at the sugar terminal, each of which handles one third of the total tonnage required.

An additional requirement involved the removal of all oversize contaminants at the out loading end of the graded sugar process. This resulted in iBulk installing three more Rotex gyratory screeners, two of which have been installed to serve as graded sugar scalpers, and the other as a caster sugar scalper.

The unique challenges of working in the food industry were also addressed by iBulk through the use of stainless steel, aluminium and FDA approved materials to ensure clean surfaces were maintained. All carbon steel was hot dipped galvanised and intrinsically safe instrumentation was installed to monitor heat to prevent potential dust ignition.

Tony adds that the success of this project is really a testament of their ability to work closely with the client and their consulting engineers to ensure the right outcomes for all parties involved.
