Document Type and Number:
Japanese Patent JP3842713
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To uniformly feed crushing raw material to a crushing chamber of a crusher by stably and smoothly rotating a material feeding rotary chute, and to prevent early damage of horizontal and vertical mechanical support parts for rotatably supporting the rotary chute.
SOLUTION: This material feeding device is equipped with the material feeding rotary chute 4; a vertical directional support mechanism provided on a main spindle upper end supporting mechanism of the gyratory crusher and rotatably supporting the chute 4 via a rolling bearing provided at a lower part of the chute 4; horizontal support rings 9A-9C disposed on the outer peripheral surface of the upper part of the chute 4 with equal angular spaces; a horizontal support ring position adjuster for adjusting the position of the rings 9A-9C advancingly and retreatingly in relation to a center of the chute 4; and a motor 11 connected to one horizontal support ring 9A among the support rings 9A-9C for rotating the chute 4.
