Pneumatic conveying benefits outweigh costs for feed mills

The first time I visited a feed plant with a pneumatic conveyor system — without knowing they had one — I noticed how super clean it was. I immediately asked if they had a pneumatic conveyor, and I must have impressed them mightily with my knowledge and experience.

There is a visible benefit to using pneumatic conveyor systems because the tubes that transfer dry material from one point to the other are sealed airtight.
A pneumatic system uses compressed air to push dry material through a tube. In contrast, other systems that use chains, buckets, disks, etc., to pull or drag dry materials along a tube do not need to be as airtight.
