For example, the feedrate and accuracy of a weighbatching system’s conveyor or feeder doesn’t exclusively determine the system’s overall capacity and accuracy. Other factors that may affect productivity and success include material delivery method, infeed rate, surge vessel capacity, weighing equipment location in relation to mixers, hopper and chute design based on the material’s physical prop...

The flow and handling of granular materials is of major importance to many industries. Yet despite efforts over several decades, the modeling of such flows has achieved only modest success. Dense gravity-driven flows in hoppers have been often modeled as elastic-plastic continua, for example. In this picture, the granular material flows as a plastic with a frictional yield condition, and deform...
