For grain:

The Kwinana grain terminal in Western Australia is currently the largest and most modern grain receiving, storage and shipping complex in the world. Receiving and unloading is at rates up to 4000 t/h, and loading vessels of more than 100,000 d.w.t. at the remarkable rate of 5000 t/h is possible. The facility includes vertical storage of 390,000 metric tonnes, and horizontal storage of about 524,000 tonnes of wheat. Modern systems of grain cleaning and treatment, dust control, fumigation, and quality control are all under the supervision of a modern computer network.

A South Australian engineering invention could save millions of dollars in repair and replacement costs of large concrete grain silos in Australia and overseas. The Tremie Tube, designed by consulting engineers Fargher Maunsell (the South Australian Branch of Maunsell & Partners Pty. Ltd.) considerably reduces the pressures on concrete silo cell walls when grain is being discharged. The Tube, approximately half the height of a concrete grain cell, is centred in the lower half of the cell. It enables the cell to be emptied in two halves, thus reducing pressures on the wall (Fig. 67).
