1. A grinding mill for processing feed material, the grinding mill comprising:
a vessel assembly mounted to a stationary frame, the vessel assembly comprising a vessel having a vessel wall with an inside surface which defines an interior area of the vessel;
a material feed supply in communication with the interior area via a feed outlet extending through the vessel wall, the feed outlet having a bottom edge and an upper edge;
a grinding assembly positioned in the vessel, the grinding assembly comprising:
a grinding ring being in fixed relation to the vessel assembly and having an axially upward facing surface and an inwardly facing grinding surface; and
a plurality of grinding rollers rotatably mounted relative to the grinding surface, the plurality of grinding rollers being configured to grind the feed material against the grinding surface;
a ramp having an upper ramp end and a lower ramp end, the upper ramp end being removably secured to the inside surface proximate the feed outlet, the ramp extending downwardly and radially inward from the feed outlet, and the lower ramp end being located radially outward from the grinding surface and radially inward from the inside surface; and
the ramp having a sloped portion between the upper ramp end and the lower ramp end, a space located between the sloped portion and the inner surface, such that the sloped portion is spaced radially apart from the inner surface, and the space and the lower ramp end are located radially outward from the rollers.
