Hopper preparation pan with edge walls

摘要

A preparation pan positionable beneath a hopper lip. The preparation pan has a surface for intercepting the free-falling curtain. There are edge walls extending from the preparation pan. The edge walls are spaced apart from the edge guides when the preparation pan is positioned beneath the hopper lip. The edge walls have an outer surface facing each edge guide. A flush issues a lubricating solution along the outer surface of the edge walls. The free-falling curtain not intercepted by the preparation pan is stabilised at each edge by the edge walls such that splattering is minimised.
