Summary

When using a spinner spreader, particle size distribution may affect a gravimetric distribution pattern, larger particles being thrown farther than smaller particles. If active ingredient (AI) concentrations were uneven with respect to particle size, it is possible that a gravimetric distribution analysis (i.e., a spreader calibration) would not accurately reflect AI distribution. This paper discusses granule uniformity and its effect on granular formulation gravimetric distribution and AI distribution. A more uniform particle size provides a more even AI distribution.
