Abstract: A shoe bracket assembly is described for mounting an impeller shoe to the horizontal rotatable turntable of a vertical shaft centrifugal crushing machine. The shoe bracket includes removable wear protector plates on opposed end faces thereof. The plates protect the rigid base member of the bracket assembly against wear. The wear plates are slidably mounted to the base member by slidable dovetail connector members and are locked into place between abutment surfaces on the base member and a back face surface of the impeller shoe. The plates can be easily removed and replaced following removal of the impeller shoe.

Abstract: An elongated impeller shoe assembly 10 is described for a vertical shaft centrifugal impact crushing machine 11 for increasing the effective utilization of the assembly and for substantially reducing the cost to utilization ratio. The assembly 10 includes an elongated supporting base member 28 for attaching to a turn-table bracket 20 in which the base member 20 is cast of a high strength steel alloy material. The base member 28 has a wide longitudinal female dovetail groove 54 formed in a front face 38 thereof extending between an inner end 32 and an outer end 34. The groove 54 has a shallow taper downward from the inner end 32 to the outer end 34. The assembly 10 includes a wear resistant member 30 mountable to the base member 28 for receiving the material from a central distribution disc 15 and directs the material radially outward along a front face 82.

Abstract: An anvil assembly 10 is described for a vertical shaft centrifugal impact crushing machine 11 for increasing the effective utilization of the assembly and for substantially reducing the cost to utilization ratio. The assembly 10 includes a wedge-shaped supporting base member 22 for attaching to a bracket 20 in which the base member 22 is cast of a high strength steel alloy material. The base member 22 has a wide longitudinal female dovetail groove 46 formed in an inclined front face 36 thereof extending between an upstream face 38 and a downstream face 40. The groove 54 has a shallow taper downward from the upstream face 38 to the downstream face 40. The assembly 10 includes a wedge-shaped wear resistant member 24 mountable to the base member 22 for receiving the particulate material from a central turntable.

Abstract: A vibratory screen apparatus is described for classifying loose solid material through horizontal screens 22-24 that are vibrated in elliptical paths by two independent eccentric weight means 28 and 30. The eccentric weight means 28 and 30 are mounted on the screen frame 15 elevationally below the center of gravity of the apparatus and upstream of the center of gravity toward the feed end. Each of the eccentric weight means include adjustable weights for adjusting the "throw" of the classifier that are outboard of bearings that support shafts that extend between the sides of the frame.
