As HPSA is an emerging technology, many feasible
design considerations are under consideration for future
trade studies to facilitate improvements in performance,
operation efficiency, durability and deployability. Moreover,
this development should be coupled with simulations and
verification testing to improve system designs to optimize
probability and frequency of collision and fracture events in
the system. These studies will inform specific modifications
to slurry transportation systems, slurry dispersion systems,
and the collision systems involved with HPSA processing.
Furthermore, these studies should balance system perfor-
mance with the goal of reducing overall energy consumption
of the system in all iterations and various design configura-
tions investigated. Additionally, the durability and reliabil-
ity of the systems can be improved through a combination
of materials selection and system design choices to reduce
wear, remove failure modes, and optimize machine uptime.
