Abstract
Vertical shaft crushers and control systems therefor are disclosed. In some embodiments a rotor of the crusher is reversible and/or autogenous. In some embodiments a crushing chamber of the crusher includes at least one anvil and at least one rock shelf chamber.
Claims25
A rotor positioned to rotate about a central axis and at least partially radially inwardly of a crushing chamber, said rotor comprising:
- an upward-facing inlet opening axial with said central axis;
- at least one outward-facing outlet opening for receiving aggregate material, said outlet opening along a first radial plane intersecting said central axis;
- a first wall arrangement disposed to a first lateral side of said first radial plane, said first wall arrangement configured to retain a first bed of aggregate material upon rotation of said rotor;
- a second wall arrangement disposed to a second lateral side of said first radial plane, said second wall arrangement configured to retain a second bed of aggregate material upon rotation of said rotor, said first wall arrangement and said second wall arrangement being generally symmetrical about said first radial plane.

A vertical shaft impact crusher, comprising:
- a crushing chamber being arranged circumferentially about a central axis, said crushing chamber comprising:
- a circumferential floor;
- an outer circumferential wall;
- a lower circumferential lip;
- a plurality of rock shelf chambers, each rock shelf chamber comprising:
- a first support extending radially at least partway from said lower circumferential lip to said outer circumferential wall;
- a second support extending radially at least partway from said lower circumferential lip to said outer circumferential wall, said first and second supports being circumferentially spaced apart such that an empty space is defined between the first and second supports;
- a plurality of anvils removably supported on said circumferential floor, said plurality of anvils supported outside of said plurality of rock shelf chambers;
- and
- a rotor disposed to rotate about said central axis, said rotor disposed at least partially radially inwardly of said crushing chamber, said rotor comprising:
- an upward-facing inlet opening, said axis extending through said inlet opening;
- at least one radially outward-facing outlet opening, said outlet opening intersecting a first radial plane, said first radial plane intersecting said axis;
- a first wall arrangement disposed to a first lateral side of said first radial plane;
- a second wall arrangement disposed to a second lateral side of said first radial plane, said second wall arrangement and said second wall arrangement being generally symmetrical about said first radial plane, wherein rotation of said rotor causes aggregate material to be thrown outward from said rotor through said at least one outlet opening toward said crushing chamber.

A method of crushing aggregate material, comprising:
- rotating a rotor in a first direction about a vertical axis;
- receiving aggregate material in said rotor;
- forming a first bed of aggregate material in said rotor;
- forming a second bed of aggregate material in said rotor;
- by rotation of said rotor, dispersing aggregate material radially between said first and second beds from said rotor such that aggregate material contacts at least one of said first and second beds;
- striking aggregate material dispersed from said rotor against a crushing chamber disposed radially outwardly of said rotor;
- and
- rotating said rotor in a second direction opposite said first direction about said vertical axis.
