Oliver Manufacturing is the leading US-based provider of reliable, durable and effective equipment for processing and refining flowing solids of all kinds.

Starting with agriculture, we have served industries the world over with a full product line that has been improved constantly for over 80 years.

Oliver Destoners quickly remove heavy contaminants from granular flowables. Precision sizers grade material by size within thousandths of an inch. Gravity table separators sort by density within a few percentage points. And fluidized bed dryers provide gentle, uniform tack-free drying after costly coatings and treatments.

We offer the first fully automated and programmable power adjustable machines, and make retrofittable enhancements for older ones, many of which have been in use for decades.

Our company designs, manufactures and ships all of our machinery from our southern Colorado headquarters to customers all over the world.
