Abstract
Vacuum filter belt apparatus has a continuous belt with an upper run at which suction filtering occurs, via passages which pass through a central thicker portion of the belt and open into a vacuum chamber. To avoid high frictional contact between the belt and the upper side of the vacuum chamber, the thick central portion of the belt passes right through the vacuum chamber from above to below and is supported below the chamber e.g. by rollers or a pressurized chamber.
