Torque Measurements and DEM Simulations in a Couette-type Device with Application to Particle Size Measurements

摘要

A continuously operating modified Cuette-type shearing device has been developed forudin-situ measurements to estimate the average particle size during size enlargementudprocesses in fluidized bed granulator. It was proven by experiments that well-definedudcorrelation exists between the mean torque and the average particle size being in theuddevice. DEM simulations revealed interesting aspects of this method.
