Abstract
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.
Claims11
A refining disk for refining a material, the refining disk comprising a base portion made of a first substance and a refining portion coupled to the base portion and adapted to engage the material to refine the material, the refining portion being made of a second substance that is harder than the first substance.
A method for refining a material comprising the steps of introducing the material between a first refining disk and a second refining disk, each refining disk having a base portion and a refining portion coupled to the base portion, the refining portions being made of a substance that is harder than the base portion and the refining portions being defined by a plurality of bumps such that the bumps of the first refining disk abut the raised surfaces of the second refining disk and
- rotating the first refining disk relative to the second refining disk so that the material is cut by the bumps as the material passes between the refining portions.
