VIBRATORY CONE-TYPE CRUSHER Russian patent published in 1995 - IPC

FIELD: crushing of materials. SUBSTANCE: vibratory cone-type crusher has concave 2 and inner crushing head 4 installed on body 1 with vertical shaft 6 for vibrations actuated by a drive made as a planetary gear with two parallel shafts with satellite gears. Unbalanced masses are fitted on the shaft, they have a phase shift that is unequal to zero. The vertical shaft has a space, in which the parallel shafts are installed. The planetary gear is a hyperboloidal gearing, whose central gear-wheel is fastened to the body mounted on springs. The satellite gears are located on the opposite ends of the shafts, and the unbalanced masses are positioned on the shafts, and the unbalanced masses are positioned on the shafts symmetrically to the vertical axis of the crushing head. EFFECT: improved design. 9 dwg
