Abstract:

The discharge spout of a grain elevator is provided with an abrasion resistant liner formed of polyurethane. The liner is formed into cylindrical configuration from a rectangular blade of material and may be readily inserted into the discharge spout and rotated relative thereto to permit even wearing of the liner. The abrasion resistant liner may be readily removed from the discharge spout and replaced with another liner to thereby eliminate any wear to the inner surface of the discharge spout.
