Segregation occurs in the formation of a traditional conical stockpile. As the product is transported by conveyor, vibration and motion of the belt causes fine particles to settle on the bottom. Coarse particles at the top of the material stream have a higher velocity as the material reaches the head pulley, and are thrown a greater distance.
2011-5-24 · Stock Pile Segregation. Stockpiling aggregate in a large conical pile can create segregation.
