摘要：
This paper introduces a model in the Discrete Element Method to simulate the mixing processes of dry materials with major water addition more realistically. The presented model covers the representation of liquid transfer from fluid particles or moist particles to dryer ones including increase in volume. Depending on the moisture content of the particles in contact, the adequate interaction model (friction, liquid bridge or suspension) and its parameters are applied.
