A rake classifier provides reciprocating movement using crank-mounted drive shafts to establish translatory forward movement as well as lifting and rearward movement of the rake structure. Rake classifier Dorr-Oliver Incorporated
Let me describe a cycle of the Rake Classifier arm to you. The arm, with a series of rakes along its length, drops into the flow of slurry and is pulled upwards. Some of the fine material will flow over, the top of the rake. The rest will be pulled along with the coarser heavier material up the incline. When the arm reaches the end of its throw it will lift the rake out of slurry allowing the

The Dorr-Oliver brand has a history stretching back almost a hundred years to a time when Dorr and Oliver were two separate companies. Founded in 1904, the Dorr Company’s initial focus was on solving processing difficulties in gold milling, but they quickly expanded into other industries on the back of successful innovations such as the reciprocating rake classifier, continuous processing thickener and
