Abstract
An apparatus for simulating the operation of a full-scale belt filter press consists of a support base, a filter belt and a press belt each anchored at one end to the support base and passing over a static curved pressure face and a winch for exerting a pulling force on the press belt against the static curved press face to remove water from a sample of slurry on or within the belts. An improvement in the method of removing liquid from a slurry with a belt filter press also is disclosed which consists of pulling the pair of belts containing a slurry against a static curved pressure face to force liquid out of the slurry.
