Difficult blending operations Available to Purchase

The assumption is often made in considering the blending or mixing of two or more phases that interparticle forces are not significant. Where one is considering components to be blended which are relatively coarse, emphasis is placed on densities and shape or geometry, but when any of the components are fine, say, below 300 BSS, surface forces on the particles of powder can exert a predominant effect. The problem of blending may become acute where a relatively coarse powder needs to be mixed with a very fine one and where there is a high ratio between the components.
