ABSTRACT:
A mineral breaker is disclosed having a rotary central shaft upon which a plurality of collars (10) are non-rotatably secured. Each collar has a first pick support ring (13) secured at each of its ends with two second pick support rings (19) slidable on the collar between the first support rings. Each pair of first and second support rings defines between them a plurality of separate locations for picks (35). An infill ring (28) formed in two halves is fitted on the collar between the two second support rings (19) and forces the rings (19) against the picks to secure them tightly in position. A pair of threaded bolts secure the two halves of the infill ring together and also allow quick and easy release of the halves, and thus removal from the collar to allow the rings (19) to be slid from the picks, when pick replacement is required.
