The superior performance of many products like paints, fillers, pigments, ceramics, or pharmaceuticals depends on the specific properties of nano‐particles. Special attention should be paid to models describing the influence of particle‐particle interactions. The experimental part of this contribution shows how rheological properties of milling suspensions change with milling time and suspension properties in the sub‐micron size range. Experimental results are related to theoretical models. The results demonstrate the key role that particle‐particle interactions play in altering the flow properties of milling suspensions throughout the process.
