A Full Line, to Cover Every Need. Gravity Separators, also known as gravity air tables or density separators, use a combination of air for weighing, vibration for fluidization and conveying and tilt (or slope) for separation. Made for ease of use, longevity and above all, accuracy, Oliver Gravity Separators sort dry, granular, free-flowing material into streams according to particle density. This density separation can effectively separate like-size particles with as little as 0.5% difference in specific density. ...Read More
Oliver offers a full line of gravity separators and gravity tables covering 11 models in several sizes and varieties, to cover the broadest possible requirements for sizing contaminant removal. Every Oliver gravity separator is backed by the longest warranty in the business: 3 years.
