Abstract: A crushing device and a method for crushing materials therewith. The crushing device includes a jaw crusher having two jaws, wherein at least one jaw moves reciprocally toward the other jaw and away from the other jaw when in use, a supply device for supplying material to be crushed to the jaw crusher, and a discharge device for discharging crushed material. The crushing device includes a housing that encloses the jaw crusher, a ventilation device provided with air outlet openings that open into the crushing space, by means of which ventilation device air can be blown under pressure between the jaws of the jaw crusher device, and an exhaust device, which exhausts air mixed with fine material produced by the jaw crusher from the housing. The exhaust device is configured to convey the fine material mixed with the air to a collecting location.

Abstract: A screening device for separating dry granular material into a fine fraction and a coarse fraction is provided. The screening device includes a drum screen defined by an open rotatable frame, which frame defines a circumferential wall, and a sheet-like screen arranged over the circumferential wall of the frame. The screening device also includes a driving device by means of which the drum screen is rotatably driven, a feed opening at a short end of the drum screen and a discharge opening at the opposite short end of the drum screen. The screening device further includes a vibration device which rotates along with the drum screen, which vibration device includes one or more vibrating elements mounted to the drum screen, which set the drum screen vibrating in use. A method for separating dry granular material into a fine fraction and a coarse fraction is also provided.
