JR Johanson's oscillating diamondback hopper, which recently received
a U.S. patent, reportedly provides reliable hang-up free flow for the
most difficult to handle materials. According to the company, the
addition of oscillating plates along key inside surfaces of a
diamondback hopper reduces a material's arching tendency by a factor
of two when compared with a regular diamondback, and by a factor of
four over a typical conical hopper. Unlike conventional hoppers,
which require large discharge openings and steep walls to achieve
flow, the diamondback hopper resolves arching and ratholing problems
using flatter angles and discharge openings one-half to one-fourth
smaller than those of conical hoppers, the company reports.
