Patent ID: 7975824

Claim:
A system for changing a flow direction of flowing grain from a first direction to at least one second direction comprising: an inlet oriented in said first direction; a flow of grain through said inlet; at least one outlet oriented in a second direction; a double-walled flow-diverting structure further comprising a core of material having a core abrasion-resistance characteristic which has more resistance to abrasion than the wall abrasion-resistance characteristic of walls of said double-walled flow-diverting structure; wherein said core is stationary in operation and configured for adjustability and comprises a substantially planar stack of a plurality of parallel layers of a first material with a substantially planar layer of second material disposed therebetween each pair of said plurality of parallel layers, wherein said second material has a higher resistance to abrasion caused by contact with flowing grain; and wherein said second material has a higher propensity to crack than does said first material when said flow impacts said double-walled flow-diverting structure.
