Assessing mixing characteristics of particle-mixing and granulation devices

摘要: Abstract The mixing of particulates such as powders is an important process in many industries including pharmaceuticals, plastics, household products (such detergents) and food processing. quality depends on the degree their constituent materials which turn both geometric design operating conditions. Unfortunately, due to lack understanding interaction between mixer geometry granular material, limited progress has been made optimizing design. discrete element method (DEM) a computational technique that allows particle systems be simulated predicted. Simulation effective way acquiring information performance different mixers difficult and/or expensive obtain using traditional experimental approaches. Here we demonstrate how DEM can used unravel flow dynamics assess several types devices. These devices for granulation particulates, are classified broadly gravity controlled, bladed high shear. We also explore role shape use test whether Froude number scaling suitable predicting scale rotating mixers.
