Refining disk
A refining disk is provided for use in various kinds of refining apparatus. The refining apparatus comprises juxtaposed disks with refining surfaces on the opposed faces, one disk rotating relatively to the other disk to work on the material therebetween. A typical refiner is disclosed in U.S. Pat. No. 3,049,307; however, the invention is applicable to various types of refiners including single rotating disk refiners and counter-rotating disk machines. Disks normally are cast which results in relatively soft low wear resistance that wear out and must be replaced regularly. The disks of this invention are constructed of the hardest wear resistant materials known including metal carbides.
