Abstract: A discharge assembly mounts inside a grinding mill on a mill shell at a discharge end of the mill and rotates about a longitudinal axis of the mill. The discharge assembly includes a plurality of ring sections forming an assembly covering the mill shell at the discharge end. Each ring section has an outer surface supported on the mill shell and inner surfaces forming a radially extending discharge passageway. Each ring section connects to an adjacent ring section to form a lapped joint therebetween and additional radially extending discharge passageways. Each lapped joint seals the mill shell from the discharge passageway to prevent discharged material contained therein from wearing the mill shell.
