Method for producing a synergistic mixture containing small granules of small particles and first material of a solid substrate having a desired particle size

摘要

A method of grinding a solid substrate in the presence of a composition of two or more milling media object in the milling chamber of a media mill or dispersing, milling media object milling a solid substrate all I give fragments of milling media object being retained with the solid substrate particles are milled in the form of a synergistic mixture produced in the grinding method is at least one composition of the media object and contributes to the above method is disclosed. To be more specifically, to a method of producing a synergistic mixture comprising having a desired particle size, small granules of a first material and small particles of solid substrate, (a) a solid substrate, fluid carrier, is given to the milling chamber of a media mill containing comprising a premix of finely divided a plurality of objects of a first material having a fracture toughness K _C2; was ground to the solid substrate to actuate the (b) the media mill, and having a desired particle size of less than or equal to the grain size S _p, part, small granules of the first material and crushed to small particles of solid substrate at least milling object of the above-mentioned first material thereof; (c) separated from the solid substrate particles and milling all objects having the S _p larger particle size dispersion; and (d) optionally, the above by removing the fluid carrier from said dispersion, and then, does not contain a fluid forming a dry synergistic mixture comprising small particulates and particles, the method is greater than the K _C1 is disclosed where K _C2.
