Without pad flights, the elevator is not cleaned out when the feed stops.
With pad flights, the elevator is cleaned out between conveying batches.
MoveMaster® En-Masse Eleveyors
Movement of the chain when buried in the material will induce the whole mass to move forward gently in a solid column. The eleveyor design permits the column of material to be moved vertically or on an inclined plane. Eleveyors are manufactured in a standard range of sizes from 200mm wide upwards, which enables them to meet every requirement.
