ABSTRACT:
An apparatus for separating stones from stone-laden earthen material, particularly material that has been previously discarded from stone quarries, includes a hopper having a conveyor that feeds quantities of stone-laden earthen material unto a bed of spiked rollers that separates the earthen material from the stones, allowing the earthen material to pass through interstitial spaces between the spikes on adjacent rollers and conveying the remaining stones to the discharge end of the bed. The detachably mounted spikes on adjacent spiked rollers are offset with respect to one another to permit the spikes on adjacent rollers to pass between each other as the rollers are rotated. The drive mechanism allows each respective spiked roller to be driven independently and at different rotational speeds relative to one another at least for short periods of interrupted operation. A collector conveyor is provided for each zone of the bed of spiked rollers that corresponds to a different type of separated material passing through the bed.
