“…Generally, the strength of adhesion force between contiguous bodies is due to Van der Waals, electrostatic and capillary forces [4,5], and the predominance of one or several of these forces depends on the actual conditions during experiments and the physiochemical properties of the materials in contact. In theory, all these forces are affected by the shape and size of the particle and the roughness of the surface, relative air humidity and pressure applied on contact [6].…”

The centrifugal technique was used to investigate the influence of particle size, applied compression and substrate materials (stainless steel, glass, Teflon® and PVC) on particle-surface adhesion force. Phosphate rock and manioc starch particles were used in a microcentrifuge that contained specially designed centrifuge tubes and reached a maximum rotation speed of 14,000 rpm. The profile of adhesion force followed a log-normal distribution and adhesion force increased linearly with particle size and the increment of the compression force. The manioc starch particles presented adhesion forces greater than those for the phosphate rock particles for all particle sizes studied. The glass substrate showed a higher adherence than other materials, most probably due to its hardness and polishing.
