Keep in mind at all times that the Oliver Specific Gravity Separator is not a "cure all" for the processor's problems. The gravity separator is a specialized piece of machinery designed to separate particles of a similar size that differ in weight, eliminating light trash. Oliver specific gravity separators should not be used as a cleaning machine to remove dust, dirt, sticks and other refuse frequently found in harvested crops. The specific gravity separator should not be used as a
sizing machine. Screening machines can do this job more efficiently. In
all processing situations, the best results are obtained on the gravity
when the product has been thoroughly pre-cleaned and sized, using the
proper equipment for those purposes. Under these conditions, the
gravity separator is able to show what it can really do!
