PROBLEM TO BE SOLVED: To prevent lowering of the precision of inspection caused by powder and to perform contamination inspection and colorimetry of a pellet in a short time with high precision. SOLUTION: This is a system for feeding pellets to a contamination inspecting device shown by a dashed line frame, detecting and removing contaminations, feeding the pellets from which the contaminations have been removed to a colorimetric apparatus after that, and performing colorimetry. Powder is removed, and lowering of the precision of inspection is prevented, by removing electricity with a static eliminator 25 fitted to a vibrating feeder 23, prior to feeding on to the turntable 31 of the contamination inspecting device. Besides, powder is removed and lowering of the precision of colorimetry is prevented, by removing electricity with a static eliminator 69 fitted to a cyclone 62, prior to the feeding to the colorimetric apparatus.
