UNBALANCED VIBRATOR CONICAL INERTIAL CRUSHER Russian patent published in 1995 - IPC

FIELD: minerals dressing and construction materials production. SUBSTANCE: bearing bush, mounted on shaft of crushing cone, has fixed on it two rings with beads opposing each other. Between them and bush there are two equal by mass loads with guiding grooves, conjugated with beads of the rings. Loads bear fixing mechanisms in the form of conical members mounted in grooves of loads and capable to be moved by screw. Sectional insert is mounted between loads. Due to free motion of loads along guides ( beads of rings) in case fixers are free easy adjustment of unbalance static moment of the structure is provided. And reliable fixation of loads in required position prevents break of fixing member and displacement load from bearing bush, that is prevents accident. EFFECT: improved loads fixation, decreased danger of its breakdown. 3 cl, 2 dwg
