The new vibration-induced pneumatic (VIP) conveying system [ 37] is able to convey bulk solids at velocities of 0.01 m/s. The system is able to convey fine powders, spray dried granules, flakes and small capsules at high mass load ratios from 40 to 200 depending on the product and pipeline length.

feeding and conveying is the size of the material that will be processed. These size variations include fine, mid-size, and coarse materials. • Fine Material: Because they tend to fluidize and flush, fine materials ranging from -50 mesh to -400 mesh do not feed well on traditional high-frequency electromagnetic feeders. The most effective way

These actions signify a critical step in the timeline of work on the Nyngan Scandium Project, as EMC breaks ground at the site, marking the physical commencement of activities under SSD 5157.

This should be avoided. The behavior of solids (powders, pellets and granules) is often counter-intuitive to the behavior of pure fluids. The guidelines presented here draw upon the collective experience of the authors and highlight key issues that need particular attention. These recommendations are by no means exhaustive, but merely …
