An apparatus for cleaning coal of extraneous matter such as gravel and the like includes a stratifying and classifying oscillating screen submerged in a liquid confining tank wherein stratification is produced by motion of the oscillating screen. The screen bottom slopes downwardly and water flow is induced from either end of the screen to aid in the stratification. The coal which rises to the top is removed by several skimmers powered by a vacuum controlled materials handling pump.
