Understanding the differences in delivery by feeders as affected by the powder properties is important for control but not much is written about this in the scientific literature. A regression analysis was undertaken to determine how to quantitatively integrate the effects of powder physicochemical properties on delivery through a twin-screw feeder. There was a linear relationship between powder delivery and screw speed over the entire operating range of the commercial twin-screw feeder test platform with the slope varying with the material delivered. Apparent particle density and particle size represented by both D50 and mode of a volume weighted particle size distribution (PSD) were found to have the most influence on delivery rate. Their effects could be quantitatively accounted for through a multiple regression equation for predicting the slope of the linear powder delivery curves. [ABSTRACT FROM AUTHOR]
