Abstract

172,525. Hardinge, H. W. Dec. 9, 1920. Rotary wet-separating apparatus.- Apparatus for treating ground materials, pulps, or slimes, for the separation of the fine material from the oversize, comprises a rotary vessel C fitted internally with scoops D which pick up the larger particles from the bottom of the vessel and pass them into a hopper E leading into a pipe F from which they are discharged by means of a current of liquid or gas or both. The apparatus is preferably combined with a grinding- mill A to which the oversize is returned by the pipe F, while the fine material is discharged from the vessel C with or without the aid of a current of air; or, in the case of a mill for wet grinding, the fine material is allowed to overflow with water from the outlet of the vessel C.
