The INDOSA electronic metal separators automatically detect and eject metallic contaminants from free falling bulk materials. Clean product passes freely through the reject assembly. A contaminant in the product stream alters the high frequency field generated by the search coil. The electronics evaluate this signal and generate an impulse for the solenoid and the double actuating air cylinder of the reject assembly. The contaminant is instantly diverted from the good product stream assuring minimal good product loss. The reject time is adjustable. In the case of several metal particles being present, the reject time will be extended accrdingly, to assure a metal free product.
