  • Patent number: 4487310
    Abstract: A metal detector device for an auger feed granulator is provided in association with the auger trough and comprises a plurality of first conductive plate elements in spaced-apart disposition axially along the bottom portion of the auger trough and a plurality of second conductive plate elements in spaced apart disposition axially along the bottom portion of the auger trough with each second plate element being disposed between adjacent pairs of first plate elements. The first and second plate elements are electrically insulated and have an upper portion disposed adjacent but spaced from the outer circumferential edge of the auger. An electrical circuit for detecting any metal object simultaneously contacting any one of the first plate elements and any one of the second plate elements is electrically connected thereto.
