JR Johanson: Oscillating Hopper

November 27, 2000
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.
