<p>An improved conveyor for handling free-flowing material wherein the conveyor includes an endless chain with flights thereon or a screw. The conveyor having a metal round bottom trough receiving a "U" shaped liner contoured to fit on top of the trough. A plurality of resilient pressure blocks butting against the edges of the liner to allow the liner to contract and expand transverse the length of the liner on top of the trough without causing the liner to buckle or become distorted. The liner is replaceable and greatly increases the wear life of the trough. The liner reduces drag and wear of the flights or screw and reduces the horsepower requirements in the conveying of the free-flowing material.</p> |
