Biological Engineering Faculty Publications

Static and dynamic coefficients of friction on structural surfaces play important roles in the power requirements and material selection for equipment used in handling and storing agricultural commodities. However, friction data on dried distillers grains with solubles (DDGS) is limited. Further, lack of a standardized method for determining friction coefficient on grain handling materials presents a challenge. This article describes studies carried out to determine the static coefficient of friction (•_s) and dynamic coefficient of friction (•_d) for corn DDGS at 10%, 8.2%, and 6.5% moisture content (all moistures are % wet basis) on eight structural surfaces: High-Density Polyethylene (HDPE), …
