Many problems associated with solids handling originate in the influence of the cohesive forces on the flow behaviour of fine powders. Therefore first it is discussed why and under what conditions the property "cohesion" is of particular interest. The results of measurements relating the dependence of cohesive forces on previous compression are then reported. A theoretical model is derived which takes into account the forces acting in interparticle contacts. The theory especially considers the increase in the adhesion forces transmitted in interparticle contacts with increasing consolidation. Permitted simplification of the theory results in a graphic representation allowing immediate visualization of the basic theoretical parameters. Determination of the latter is possible directly, by means of shear tests on cohesive powders. The usefulness of the theory is demonstrated through the representation of unconfined yield stress characteristics of various powders. |
