Discrete element method simulation of a conical screen mill: A continuous dry coating device

Discrete element method (DEM) is used to investigate the comil (conical screen mill), which is a continuous powder processing device, recently gaining popularity for dry particle coating. Simulations show that the mean residence time (MRT) is one of the most critical parameters, and along with the process and collision dynamics can explain comil dry coating results, and may allow selection of experimental operating conditions.393
