Micro-mill-mixer

Claim 1

A micro-mill mixer comprising in combination: an enclosure for treating material, the material including particles carried in a fluid, the material to be accelerated in said enclosure, an inlet means in said enclosure for introducing material to be treated into said enclosure, an outlet means for discharging from said enclosure material for which treatment has been completed, at least one abrasive member having at least one face provided with an abrasive coating forming hard, sharp crystalline cutting points, at least one accelerator means for providing both centrigufal and centripetal motion to said material, said accelerator means having internal conduits ejecting the particles and fluid toward the abrasive member and means for effecting flow of material into said accelerator means, so that ejected material continuously re-enters the accelerator means to effect repetitive circulation, said accelerator means and said abrasive member being positioned relative to one another so that the particles and the fluid are projected onto said abrasive member and against said abrasive coating to produce intense splitting, slicing and particle shearing as well as fluid division jointly with coating of said particles by said fluid to form an intimate mix, and said accelerator means and abrasive member being furthermore positioned so as to provide a continuous repetitive circulation of said particles and fluid over said abrasive member.
