Discharge cone assembly adapted to be mounted inside a rotary grinding mill or the like is disclosed, in the preferred embodiment, including first and second holders, first and second wearable inserts, first and second cover plates, a wearable nosepiece, and first and second securing plates. The rotary grinding mill includes discharge assemblies having discharge chambers. The ground material from the mill flows into the discharge chambers through grates formed in the discharge assemblies. The holders are permanently mounted in the mill for receiving the wearable inserts. The preferred inserts are captured within the holders by the cover plates and are in ground material communication with the discharge chambers of the discharge assemblies. The nosepiece is in ground material communication with the first and second inserts and provides a unitary outlet therefore. The nosepiece is secured to the holders and the inserts by studs formed on lips projecting from the holders which are received in apertures formed in the nosepiece and by securing the securing plates to the nosepiece and to the holders and the inserts. The nosepiece is separately removable and replaceable without removing the holders, the inserts, or the cover plates by removing the securing plates and raising the nosepiece so that the studs of the lips on the holders do not extend into the apertures of the nosepiece.
