Metal detectors are used to avoid metal contaminations present in the bags. They have a tunnel-shaped or round opening, through which the product is guided. The electro mechanical field is created in the tunnel area(Aperture) of the metal Detector. Irrespective of the shape, the inside of a metal detector consists of detector and receiver coils.
When a Bag containing metal particle passes through the aperture area, there will be signal fluctuation and that will be picked by the control system. The Control system then triggers the reject mechanism, for stopping the conveyors belt or pneumatically operated reject mechanism.
Metal Detector Systems with eject flap or swivel funnel are used for the separation of metal contaminants from bulk materials in free fall. Using easily available standard connections such systems can be easily integrated into existing pipes. A sophisticated design prevents back jamming, clogging, the formation of material deposits, allows thorough and time-saving inside cleaning. All the system components are designed to meet the stringent hygiene requirements in the food industry.
