Abstract
An annular shear cell has been employed to measure the shearing properties of lactose powder coated with up to 104 mol g−1 of powder of a series of paraffin hydrocarbons. The angle of internal friction, Δ, of the coated powders was independent of their packing density. The shearing properties of the powders depended on the concentration, the viscosity and thickness of the coating material.Keywords
