Electronic metal detectors avoid machinery damage

A comprehensive range of electronic metal detectors manufactured in Australia eliminates unwanted tramp metal from materials-hand-ling equipment used in food, mining and other industries. The Australian company, T.S.S. Company Pty, Ltd, has achieved world-wide recognition for its range of metal-detection and associated conveyor equipment. The company’s electronic metal detector, marketed under the name Detec, is designed to locate and eliminate tramp metal from conveyor systems used in brickworks, quarries, timber and steel works, bottling plants and all mining applications.

Unwanted tramp metal can cause lost production and costly damage to expensive machinery and con-

veyor belting. Extractive magnets are used extensively but cannot provide complete protection because tramp may be caught under the burden, or knocked off the magnet face, and metals without magnetic properties will not be detected. However, the Detec device will locate tramp metals which are ferrous or non-ferrous either by detector alone or with magnets.

The electronic metal detector comes in a standard model which suits most applications. However, the company will build units to suit buyer requirements. The equipment is weatherproof and designed to withstand arduous conditions frequently encountered in mines and quarries. A recent addition to the

Detec range is the liquid and paste detector designed to automatically reject metal in all pumped and clean-in-place (C.1.P.) systems used in the food industry.

Metal detection in the food industry is aimed at preventing contaminated products reaching the consumer, rather than protection of machinery. Therefore, the size of the metal pieces which need to be detected is more critical.

The Detec liquid and paste detector has a Fiskar clear-door polycarbonate control box sealed to 1P65 standard, and equipped with a red warning light, sensitivity control reset button, and stop controls on detection of metal. The metal detector sensing head should be located

in the production system where the product is in its smallest form or package but not vulnerable to further contamination.

The sensing coil relies on conductive metal absorbing some of the field’s energy, and any metal with conductive properties will cause the unit to trigger. Also in the Detec range is the T.S.S. Walkthrough Metal Detector, a security device used by corrective services departments and airport authorities to screen passengers.

The company’s conveyor belt cleaner, marketed under the name “Concord,” is widely used throughout the mining industry in Australia and overseas. The system is reliable, efficient and suited to a wide range of applications.
