FIELD: materials separation technique. SUBSTANCE: triturator has horizontal drum having a perforated shell. An endless flexible pressing belt is mounted to define with the shell a wedge-like gap which narrows in the direction of the belt travel. The triturator further has a squeezing roller adopted to press the belt to the drum shell, and a clamp means having the form of a shoe. The shoe is positioned in the narrowing area of the wedge-type gap. The shoe has a concave recess. The depth of the recess is sized to decrease toward the perforated drum disposition and is equal to zero in the proximity of the drum. The shoe is provided with adjustable springs adopted to bring it in a flexible contact with the pressing belt in the area of drum perforations. EFFECT: improved quality of separation.
