This paper considers the performance characteristics of a brush-based material-transfer system, and the frictional interactions that result from the presence of particulate contaminants. The analysis of the dynamics of spherical objects transported through a cartridge by the brush is applied to isotropic and anisotropic belt designs. Experimental measurements of the load on individual objects, obtained using an instrumented cantilever, are compared with the predictions from a heuristic model, as well as preliminary observations from a qualitative bifurcation analysis of a piecewise-smooth dynamical system, in which a spring-loaded object slides along a looped belt with patches of distinct frictional properties.
