Induction sensor system for ferrous, non-ferrous and stainless

MSS’s MetalSort is engineered to provide accurate separation of ferrous, non-ferrous and stainless steel from mixed input material streams. These units are ideal for use in separation applications in glass cullet, plastic flake and at e-scrap facilities. Particles down to less than 2 mm in size are acurately detected and removed by precisely-pulsed air jets.

The MetalSort can be configured in a slide or conveyor arrangement, requires little space, and can easily be integrated into existing processing systems. Units can also be built in different machine widths, and the coil configuration and resolution can be tailored to specific processing applications.

Sized incoming material is distributed over the machine width by a vibratory feeder. At speeds of about 500 feet/minute (2.5 m/s) material travels across the array of detection coils which are mounted directly underneath the slide or conveyor belt.

Induction-based sensors detect small variations in the electromagnetic field which are generated by metal particles, and ferrous, non-ferrous and stainless steel can be identified independently if required. State-of-the-art electronics process the detected signals and activate the corresponding air valves, which eject the metals upward or downward into a chute or ejection hood. Capacities are two tons/hour for plastic flake and glass cullet and 3.75 tons/hour for e-scrap, with removal efficiencies of 95 percent. Available options include a colour touchscreen interface and remote modem or ethernet access.
