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.
Claims25
The combination of a conveyor bearing granular coal, aggregate, or other granular material within a given granular size range, at least one impact surface against which a stream of granular material impacts when material is input to or discharged from the conveyor, and a liner for the impact surface, the improvement in the liner which comprises:
- a base plate of molded elastomeric material,
- a plurality of walls upstanding from the base plate and integrally molded therewith, said walls and base plate defining a plurality of pockets opening outwardly from the impact surface, whereby at least some of the pockets are sized to collect and accumulate granular material to define a renewable wear surface along the impact surface.
An impact liner for a conveyer moving granular material between two stations to provide a wear surface for a stream of material at the input or output end of the conveyer, said liner comprising:
- a base plate of molded elastomeric material,
- a plurality of walls upstanding from the base plate and integrally molded therewith, said walls and base plate defining a plurality of pockets opening outwardly from the impact surface, whereby at least some of the pockets are sized to collect and accumulate granular material to define a renewable wear surface along the impact surface.
An impact liner for the impact surface of a screen deck in a classification machine against which granular material impacts,
- said liner comprising:
- a base plate of molded elastomeric material,
- a plurality of interconnecting walls upstanding from the base plate and integrally molded therewith, said walls and base plate defining a plurality of outwardly opening substantially identical pockets, whereby at least some of the pockets are sized to collect and accumulate granular material to define a renewable wear surface along the screen deck.
