IMPROVED FEED DISTRIBUTOR FOB A CRUSHER THIS SPECIFICATION CONTAINS THE AMENDMENTS

摘要

A feed distributor is shown mounted above a frame and annular crushing chamber of a gyratory crusher. The distributor has a cylindrical feed wall with an annular flange at its lower end adapted to be removably attached to the crusher frame, and a plurality of arms projecting radially inward from the feed wall to support a platform centrally located within the feed wall. A feed chute is supported on the platform for rotation about a vertical axis centrally located with regard to the feed wall and annular crushing chamber. The chute projects radially outward and downward from a point where the chute intersects the vertical axis about which the chute rotates. A feed hopper is supported by the feed wall over the chute and the hopper has a discharge spout coaxial with the vertical axis about which the chute rotates. A driving motor is supported by the feed wall and is drivingly connected to the chute to rotate the chute and turn the lower and discharge end of the chute in a horizontal annular path above the annular crushing chamber to discharge feed falling through the discharge spout of the hopper downwardly and outwardly from the lower end of the chute into and around the annular crushing chamber of the crusher. The entire feed distributor, including the cylindrical feed wall, may be pre-assembled and mounted on top of a crusher as a single unitary assembly, and removed therefrom as a single unitary assembly, thereby providing easy assembly, disassembly and access to the top of the crusher.
