UNIT WITH TOROIDAL WORKING CHAMBER FOR MAKING MORTARS Russian patent published in 2012 - IPC B28C5/00 

FIELD: process engineering.

SUBSTANCE: invention relates to preparation of mortars. Proposed unit comprises working chamber mounted elastically on bed and equipped with drive. Said chamber is shaped to torus with bicurved wavy multi-start screw surface provided with screw grooves, inside and outside of said chamber, arranged at surface axis and shaped to curvilinear pockets with centers of curvature located inside and outside of said chamber. It is composed of sections, each being shaped to circular sector composed of coiled strip to make different-size quadrangles with two parallel sides. Note here that said sections are interconnected by free sides of said quadrangles to hollow working chamber with wavy screw surfaces in the form of curvilinear pockets that differ in shape and size. Note here that distance between bend lines equals the sum of inner and outer surface pocket perimeters.

EFFECT: expanded operating performances, smaller overall dimensions.
