The processing of powders and granules, also called bulk solids technology, is of great importance for various branches of industry, such as the chemical, pharmaceutical, coating, food and feed industry. Depending on the sector, the degree of solids involved can vary from 30-80% of the total product flow. In each of these processes the physical properties (such as cohesiveness, particle size distribution, compressibility, density, etc.) of powders and granular material will greatly affect the quality of the product and the flow properties of powders. Especially in the latter case, powders differ greatly from liquids and gases. Powder particles and granules can also experience wear during production, storage and (pneumatic) transport. The forces encountered can be divided into impact forces, compressive forces and abrasive forces. Impact and compressive forces can break powder particles and granules whereas abrasive forces can cause fines and dust, and this is often an undesired phenomenon.
After the course you understand the basic concepts of processes and techniques in which powders and granules play a role. You will be able to design or modify a process in such a way that it is optimally adapted to produce products with the desired properties. On the basis of the many examples, you develop a comprehensive understanding of how powder and granulate properties can be decisive for the final application and how to adapt these.
