Abstract
A sample of powder granules flowing through an online conveyor is removed periodically and fed to a supply hopper where a predetermined amount of granules are stored. A small portion of the granules are removed from the supply hopper and continuously fed to the upper surface of a rotary table to form a single layer thereon. The sample on the table is optically sensed to detect foreign particles. The foreign particles are removed and subsequently the good particles are removed and passed to a weighing hopper. The ratio of good product after sensing and the sample in the hopper is calculated to determine the relative amount of foreign particles flowing in the system.
