Description

Eriez Metalarm Metal Detectors from HMA Wear Solutions comprise a range of industrial units designed to protect a range of machinery from damaging tramp metals. Sensitivity is determined by a function of the width of the search coil, the height of the product, and the type and size of the metal being detected. They are easy-to-install, without the need to cut the belt, and include a signal monitoring and self-check facility, mechanical relays to actuate reject devices and alarms, high-level immunity to radiated signals, high-density polyethylene-encased search coils, and CE certification. Both ferrous and non-ferrous metals can be detected.

For use with angled trough conveyors, Eriez Model TR Metalarm from HMA Wear Solutions is ideal for detecting large tramp metal. The Model TR is used in a variety of industries, such as wood, plastics, aggregates, and mining. The lightweight design provides easy manoeuvrability and quick installation. In most cases, it can be installed with little or no adjustment to idler spacing. Units can be supplied for belt widths from 400 mm up to 2000 mm. The Model TR Metalarm from HMA Wear Solutions is equipped with either a Model 3400 or a Model 3400/QM2 control.
Similar to the Model TR Metalarm, the Model BR Metalarm (bridge design) from HMA Wear Solutions is excellent for detecting tramp metal in burden depths greater than 356 mm. The Model BR is available in a series (standard) or transmit/receive mode. The transmitter/receiver coil combination makes it ideal for mineralised materials, and also for use when nothing smaller than a certain size metal should be detected. This removes the risk of ‘nuisance trips’ for small metal pieces that will not damage machinery, thereby reducing costly downtime. Its lightweight design makes it cos- efficient to install on most trough belt conveyors.

For flat-belt conveyor applications, Eriez Model PL from HMA Wear Solutions is supplied with a Model 6600, 3400 or 3400/QM2 control. The unit is easy to install, and is especially effective for picking up metal contaminants where the search coil is surrounded by metal conveyor frames, or moving metal like mobile crusher applications. The Model PL2 has been developed specifically for direct attachment to lightweight conveyors used to feed granulators with tops and tails and sprues, etc. from moulding machines of all types. It prevents the majority of small metal pieces of all types from entering granulators, damaging blades and contaminating the granules produced.

The Eriez Model VC from HMA Wear Solutions offers an all-in-one unit, including search coil and metal-free section. It is supplied with a Model 3400 control connected to the search coil integrated into the tray’s trough section. When metal is detected, the conveyor and material flow is stopped to allow for manual removal of the metal. Audible and visual alarms are available as optional extras.
