A distributor plate (10) is shown for use in an impelling rotor of a vertical shaft impactor (14). Typically the impelling rotor is a chamber (12) arranged to rotate about a vertical axis A-A. Feed materials for breakage are gravity-fed into the rotating chamber (12). These materials strike the rotating distributor plate (10) which is located at the base of the rotor chamber (12). The plate has a substantially planar single-piece upper surface (24) onto which the feed materials are received. This substantially flat surface (24) facilitates rapid and easy expulsion of feed materials there across and out of the rotor chamber (12). The plate shown is a circular disc made of metal carbide. Use of a single-piece upper surface of the distributor plate (10) also will not result in the development of preferential wear sites at corners, edges, join lines etc, as can happen with the known distributor plates.
A distributor plate for an impelling rotor of a rotating shaft impactor, where the impelling rotor is a chamber arranged in use to rotate about an axis and to radially eject material received therein through one or more ejection ports in a side wall of the chamber, the distributor plate being in use held in a fixed position with respect to the impelling rotor wherein the distributor plate includes a body and a single wear element only, the single wear element being positioned on the body to alone cover an outer surface of the body onto which the material would otherwise be received.
A distributor plate for an impelling rotor of a rotating shaft impactor, the distributor plate including a wear element positioned on a body, the wear element spaced from the body by one or more spacers arranged between facing surfaces of the body and the wear element so that, when the element is attached to the body by use of an adhesive substance, the spacer(s) allow for a predetermined depth of the adhesive substance between the body and the wear element.
A distributor plate for an impelling rotor of a rotating shaft impactor, where the impelling rotor is a chamber mountable via a coupling element to a shaft of the impactor and arranged in use to rotate about an axis and to radially eject materials received therein through one or more ejection ports in a side wall of the chamber, wherein the distributor plate has a basal spigot, with a cavity in the spigot for receiving the coupling element therein in use.
A distributor plate for an impelling rotor of a rotating shaft impactor, where the impelling rotor is a chamber arranged in use to rotate about a rotating axis and to radially eject materials received therein through one or more ejection ports in a side wall of the chamber, wherein at least part of a peripheral edge of the distributor plate is bevelled for the insertion of a levering tool to facilitate movement of the distributor plate.
A distributor plate for an impelling rotor of a rotating shaft impactor, where the impelling rotor is a chamber arranged in use to rotate about a rotating axis and to radially eject materials received therein through one or more ejection ports in a side wall of the chamber, the distributor plate including a single wear element positioned on a body to alone cover an outer surface of the body and either of an opposing surface of the body or the wear element including a projection which locates the wear element on the body.
A mounting for supporting a distributor plate in an impelling rotor of a rotating shaft impactor, where the impelling rotor is a chamber arranged in use to rotate about an axis and to radially eject materials received therein through one or more ejection ports in a side wall of the chamber, the distributor plate having a multi-sided basal spigot receivable in a multi-sided recess in the mounting, wherein the number of sides of the recess is a multiple greater than one of the number of sides of the spigot.
