FIELD: disintegrators and devices for crushing.SUBSTANCE: invention is intended for grinding of materials. Roll crusher comprises housing, drive roller and fixed jaw with gap between them. Fixed jaw has bending away from roller. Bending line matches with roller horizontal axis. Maximum jaw angle of deviation from vertical line is determined depending on grip angle, friction coefficient between roller and crushed piece and friction coefficient between fixed jaw and crushed piece.EFFECT: higher degree of crushing.1 cl, 3 dwg |
