Abstract: A vibrating jaw crusher which includes a housing, in the inside of which there are operatively mounted a pair of working jaws. The pair of jaws includes at least one movably mounted jaw. The working surfaces of the rigid and the movable jaws are shaped in the form of a convex and a concave broken (polygonal) line, respectively. The movable jaw is driven by means of a vibrator. The movable jaw is supported by means of elastic elements connected to the top and the bottom end of the jaw. In a preferred embodiment of the invention the rigid and the movable jaws are fastened by means of an axle at their top ends, while their bottom ends are supported by means of elastic elements, which are shaped as rubber pads.

Abstract: A vibrating screen which comprises a housing having screening surfaces, the surfaces forming an angle with respect to each other, and vibrators. The housing consists of separate sections having screening surfaces arranged, one underneath the other, inside of each section. Each section is suspended to a frame by means of flexible joints. Vibrators are mounted to each section. The screening surfaces of the separate sections are arranged at different inclinations and have different widths in the downward direction of motion of the material passing through the vibrating screen device.
