The bottoms of chutes are frustums of cones or truncated pyramids to aid the discharge of materials. Good chute design requires more than having the correct cross-sectional area and slope. When bulk material discharges to a chute and impacts the chute surface, its velocity decreases. The larger the impact angle, the bigger the change …
