IMPROVED HANDLING OF GRAIN IN COMMERCIAL ELEVATORS

The specific goals of the expanded research are to: 1. Develop two-dimensional mechanistic models of grain commingling in lab-scale and full-scale bucket elevator boots. Appropriate modeling methods have been identified¿the discreet element method will be used¿and needed grain physical properties have been tabulated from the literature. 2. Determine the effect of repeated handling on particle size distribution of dust emissions from corn and wheat during elevator handling. Experimental protocols were developed during testing with feed pellet handling that can be applied to measurements with wheat and corn.
