Abstract

The repeated filtration of substances contg. very fine binder particles, comprises using a frame and a plate, between which a perforated elastic material is clamped so the perforations form very fine slots with a width smaller than the very fine binder particles; after filtration, the clamping force is released so the perforations resume their normal shape and are automatically cleaned. The filters are esp. used to remove water from concrete mixts. in the mfr. of prefabricated concrete building elements by the implosion- or vacuum- moulding process. They are re-usable and self-cleaning, and replace expensive filters and/or filters which must be removed and subjected to slow and costly cleaning operations.
