Experiments and discrete element simulation of the dosing of cohesive powders in a simplified geometry

We perform experiments and discrete element simulations on the dosing of cohesive granular materials in a simplified geometry. The setup is a canister box where the powder is dosed out through the action of a constant-pitch coil feeder connected to a motor. A dosing step consists of a rotation followed by a period of rest before the next step. From the experiments, we report on the operational performance of the dosing process through a...
