Abstract
A roller press comprised of two opposed porous tubular sleeves which are forced together to form a nip by inner driven rollers. Liquid from a mixture fed through the nip is forced into the porous rollers and is transported by them to another circumferential location where the liquid is forced out by a compressed air stream. Filtration belts cover portions of the porous rollers in the areas of the nip.
