CONE-TYPE VIBRATING CRUSHER AND METHOD FOR ADJUSTING OPERATION OF SUCH CRUSHER

摘要

The invention relates to crushers wherein the material is crushed between a cone (10) and a bottomless frustroconical body (18) surrounding the cone and wherein the body is mounted on a frame (20) movable with respect to the structure and provided with means (24) capable of transmitting circular, substantially horizontal oscillations or vibrations to the body. In order to control operation of the crusher and to provide for improved monitoring of its operating status, while increasing the useful life of the working surfaces, the cone (10) is mounted on its support (16) in such a way as to rotate freely and is provided with means (28) for measuring the rotation speed thereof about its axis of connection with means (32) of adjustment of the frequency and/or amplitude of the vibrations or oscillations of the body.
