Abstract: An impact liner for providing a renewable impact surface for granular materials at the input or output end of a conveyer or along a screen deck. The impact liner is of molded elastomeric material and includes a base plate having a plurality of walls upstanding therefrom and integrally molded therewith to define a plurality of pockets opening outwardly for accumulating at least some of the granular material to define a renewable wear surface.

Abstract: An impact liner for an impact surface in a chute of a conveyor or on a screen deck in a granule classification machine, the conveyor bearing granular coal, aggregate, or other granular material which is within a given granule size range. The chute has at least one impact surface against which the granular material impacts when the material is input to or discharged from the conveyor; usually, there are plural impact surfaces in the chute. The chute or impact liner includes a base plate of molded elastomer conforming to and mounted on the impact surface of the chute or on a screen deck. A multiplicity of elastomer knobs are molded integrally with the base plate and project toward the interior of the chute when the liner is mounted on the chute impact surface.

The chute has at least one impact surface against which the granular material impacts when the material is input to or discharged from the conveyor; usually, there are plural impact surfaces in the chute. The chute liner includes a base plate of molded elastomer conforming to and mounted on the impact surface of the chute. A multiplicity of elastomer knobs are molded integrally with the base plate and project toward the interior of the chute when the liner is mounted on the chute impact surface. The knobs are of truncated conical configuration and are effectively spaced from each other by distances greater than the size of the smaller granules of the granular material, so that granular material accumulates between the knobs to afford a renewable wear surface within the chute.
