Vertical shaft impactor with externally adjustable anvil ring

A vertical shaft impactor, comprising:

• a housing including an outer wall that defines an interior chamber, the outer wall further defining a cutout portion;
• a lid coupled to the housing for closing off the interior chamber;
• an anvil ring disposed within the interior chamber;
• a bolt assembly coupled to the housing, the bolt assembly comprising a bolt housing and a bolt that moves in a longitudinal direction within the bolt housing;
• wherein, the bolt housing comprises at least one side having an open face for receiving the anvil ring;
• wherein, the bolt is coupled to the anvil ring such that longitudinal movement of the bolt induces longitudinal movement of the anvil ring.

A vertical shaft impact crushing apparatus, comprising:

• a housing;
• a chamber defined within the housing, the chamber having a central region and an outer periphery;
• a lid for closing the chamber, wherein the lid defines a plurality of openings positioned about the perimeter of the lid;
• an anvil ring configured to be disposed within a housing of the vertical shaft impactor, the anvil ring comprising at least one tab extending radially outwardly;
• an elongate jack bolt having a first end and a second end, the bolt including a threaded portion formed between the first and second ends;
• a jack bolt housing having a cover and a door, the jack bolt housing configured to be coupled to the housing;
• and
• a first locking collar and a second locking collar each coupled to the jack bolt, where the first locking nut is coupled to the jack bolt on one side of the at least one tab, and the second locking nut being coupled to the jack bolt on the opposite side of the at least one tab;
• wherein, the jack bolt is movable along a longitudinal axis within the jack bolt housing between a first position and a second position;
• further wherein, a movement of the jack bolt along the longitudinal axis induces longitudinal movement of the anvil ring.
