A chute liner for an impact surface in a chute of a 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 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. Fasteners are provided for mounting the chute liner in the conveyor chute with the base of the liner covering at least a portion of the inner impact surface of the chute.
