Oliver Separation Equipment

The best in the world.

Made for ease of use, longevity and above all, accuracy, Oliver Gravity Separators come in several sizes and varieties – so chances are, you’ll find just the right equipment for your particular separation needs.

Oliver Gravity Separators separate dry, granular, free-flowing material according to particle density. Like-size particles can be effectively separated with as little as 0.5% difference in specific density. Separators use a combination of air for weighing, vibration for fluidization and conveying and tilt or slope for separation.

Machines can be adjusted during operation with little training using simple controls. Easily control each fan individually, adjust for eccentric speed, side and length tilt as well as feed rate.
