Bulk homogenisation and dust binding

The ability to mix and wet powders is as old as human civilisation. Druggists and dyers used mortars and crushed powder particles in crucibles to increase the surface area of the mixed material particles. In this way, crushing and bulk mixing were carried out simultaneously. From a strictly scientific point of view, further changes were made to the powder particles. Electron microscopic observations show how diverse and individual powder particles can change. Clumpy powder deagglomerates, dry particles wet and coat themselves with finer fractions, dispersed particles agglomerate, absorbers can dehumidify powder, dispersions can crystallise under pressure and friction.
