Cone or gyratory stone crusher moving jaw fixing has locking member with radial notches to receive matching tongues on jaw

摘要

The fixing for a moving jaw (4) on the conical head (5) of a stone crusher has a locking member (16) fastened to the head and made with a series of radial notches (15) facing outwards and spaced evenly round its periphery. The inner periphery of the jaw has an equal number of inward-facing radial tongues (14) on the level or its upper aperture mthat engage with the notches, fixing the locking member to the jaw so they rotate together. The notches and tongues are e.g. four in number.
