ABSTRACT:
A method of detecting and sorting pieces of insulating materials admixed in small pieces of conductive materials, which comprises detecting and amplifying the surface potentials of the conductive materials and the insulating materials by a surface potentiometer on the basis of a time differentiation method, inputting the signal to a comparator, and sensing the presence of the insulating materials. This method is utilized to detect and sort plastics admixed in pulp and papermaking materials or cereals.
