Pneumatic Conveying vs Mechanical Conveying
In most cases, if your rate is < 2,000 lbs./hour or if you are conveying < 50 feet with 2 or fewer changes in direction, mechanical conveyors are going to make more sense. Things like flex augers, buckets elevators, aeromechanical/tubular drag conveyors can handle these applications well, with less cost and lower head room requirements.
