Abstract

See full text

A retainer assembly for securing a mantle to a mainshaft of a gyratory crusher. The retainer assembly includes a headnut and a burn ring that are joined to each other prior to installation. The headnut includes a first and a second series of bores that each extend though the annular headnut. A series of jacking bolts are installed in the second series of bores and a series of connector are installed in the first series of bores. The combination of the headnut and burn ring are installed on the mainshaft. Once in place, the connectors are removed and a series of cylinders are positioned in the first series of bores. The cylinders are pressurized to create a gap between the headnut and the burn ring. The series of jacking bolts are rotated to maintain the gap and one or more shims can be positioned in the gap. The cylinder are removed and a headnut cover is installed to protect the headnut. During removal of the headnut, the cylinders can be reinstalled and pressurized.
