It is the basic objective of a solid mixing process to avoid any segregation effects. Especially free-flowing bulk solids with weak interparticle adhesive forces tend to percolating segregation. Liquid addition, which is common in mixing granulation processes, will usually reduce the particle segregation due to pendular liquid bridge networks. However, liquid addition can result in a change of the segregation mechanism. For example: water may accumulate selectively in one component when hydrophilic and hydrophobic solids need to be mixed. Heteroagglomerates that consist mainly of one solid component may arise and degrade the final product quality. In this work the Discrete Element Method (DEM) is applied to investigate mixing and segregation of moist particulate solids in more detail. During particle collision liquid is transferred from one to the other contact partner until the liquid is uniformly distributed in the bulk. The available liquid bridge models assume complete particle wetting or neglect that the mixing components may differ in their contact angle. We developed the liquid contact dispersion model further in order to realize partial particle wetting that includes drop formation on the particle surface. A comparison between the common film model and the proposed model shows an improvement in experimental validation when the partial particle wetting model is included in the DEM simulation. The assessment of these models is carried out by evaluating mixing efficiency and liquid distribution. (C) 2018 Published by Elsevier B.V.
