The distribution of foreign material (chaff and fines) was studied in a4.6-m-diameter bin filled with Tobin canola. The bin was filled twice using a central spout and once using a conical spreader. The distribution of chaff and fines can be described using a quadratic equation with radial coordinates. The use of a conical spreader to fill the bin with canola increased the uniformity of chaff and fines distribution only slightly. Contrary to general belief, fines were not highly concentrated in the center of the bin for either of the fill methods. The variation of chaff and fines with height was insignificant.
