An atomizer wheel for the atomization of suspension of abrasive materials, comprising a hub, an outer wall part coaxially disposed about said hub and a bottom part connecting said outer wall part with said hub, a ring-shaped cover member detachably connected to said outer wall part, said outer wall
An atomizer wheel for the atomization of suspension of abrasive materials, comprising a hub, an outer wall part coaxially disposed about said hub and a bottom part connecting said outer wall part with said hub, a ring-shaped cover member detachably connected to said outer wall part, said outer wall part, said hub, said cover member and said bottom part defining between them a toroidal chamber, said cover member having an inner circumference defining together with said hub an unobstructed annular space in communication with said toroidal chamber, said outer wall part being provided with a plurality of regularly shaped holes uniformly distributed around the circumference of the outer wall part, said holes forming the only outlet openings of the wheel, each of said holes being lined with a bushing of wear-resistant sintered material, said holes and said bushings being tapered in direction radially outwardly from said chamber, the inner end of each of said bushings projecting into said chamber while their outer ends are substantially flush with the outside of said outer wall part and an annular plate of wear-resistant material embedded in and clamped against the surface of said bottom part, facing said toroidal chamber. 13. An atomizer wheel for atomization of a suspension of abrasive materials, comprising an upstanding hub, an outer wall member coaxially disposed about said hub, a bottom member connecting said outer wall member with said hub, the upper surface of said bottom member being of a wear-resistant material, a ring-shaped cover member detachably connected to the upper edge of said outer wall, said hub extending upwardly at least to the level of said cover member, said outer wall member, said hub, said cover member and said bottom member defining between them a toroidal chamber, said cover member having an inner circumference defining, together with said hub, an annular inlet opening in communication with said toroidal chamber, said outer wall member being provided with a plurality of uniform outlet openings uniformly distributed about the periphery of the outer wall part and forming the only outlet openings of said wheel, and a bushing of wear-resistant sintered material extending radially through each opening and projecting into said chamber, said holes and said bushings being tapered in a direction radially outward from said chamber. 14. An atomizer wheel for atomization of a suspension of abrasive materials, comprising a hub, an outer wall part coaxially disposed about said hub and a bottom part connecting said outer wall part with said hub, a ring shaped cover member detachably connected to said outer wall part, said outer wall part, said hub, said cover member and said bottom part defining between them a toroidal chamber, said cover member having an inner circumference defining together with said hub an unobstructed annular space in communication with said toroidal chamber, said outer wall part being provided with a plurality of regularly shaped holes uniformly distributed around the circumference of the outer wall part, said holes forming the only outlet openings of the wheel, each of said holes being lined with a bushing of wear-resistant sintered material, said holes and said bushings being tapered in direction radially outwardly from said chamber, the inner end of each of said bushings projecting into said chamber while their outer ends are substantially flush with the outside of said outer wall part, said bottom part having a sintered wear-resistant surface coating facing said toroidal chamber. 15. The atomizer wheel of claim 13 in which each of said bushings is of a single piece wear resistant sintered material having a smooth outer wall free of outwardly extending protrusions or flanges. 16. The atomizer wheel of claim 13 in which the wear resistant material on the upper surface of the bottom member extends continuously thereover and upwardly along part of the height of the peripheral surface of the hub. 17. The atomizer wheel of claim 12 in which the wear resistant material of the bottom surface is more wear resistant than the remaining surfaces of the inner toroidal chamber. 18. The atomizer wheel of claim 12 in which the toroidal chamber constitutes the entire interior volume of the atomizer wheel. 19. An atomizer wheel for atomization of a suspension of abrasive materials, comprising: a hub having a vertical axis; a single, unitary, cylindrical outer wall coaxially disposed about said hub and having top and bottom ends and having an inner surface and an outer surface, said inner surface having a vertical height less than the length of the axis of said hub; a bottom part extending perpendicularly from said bottom end of said cylindrical outer wall to said hub; a ring-shaped cover attached to said top end of said cylindrical outer wall, said cover having an outside edge and an inside edge; said inside edge having a diameter greater than the diameter of said hub and the center of said cover being co-axial with the axis of said hub, the inside edge of said cover and hub defining between them an unobstructed annular space in communication with the interior of said atomizer wheel; said inner surface of said cylindrical outer wall, said cover, the portion of said hub having an axis coextensive with the height of said inner surface and said bottom part defining a toroidal chamber constituting the entire interior volume of the atomizer wheel; said cylindrical outer wall having bushing receiving holes uniformly disposed therein, each hole having an integral sidewall defining a truncated cone and having an inlet disposed along said inner surface of said outer wall and an outlet disposed along said outer surface of said outer wall, each said inlet being larger in diameter than its respective outlet; a bushing, made of wear-resistant sintered material having a smooth outer wall free of outwardly extending protrusions or flanges inserted in each said bushing receiving hole, each said bushing having the shape of a truncated cone over its length, said shape being congruent with the shape of its respective bushing receiving hole so that the outlet end of said bushing is flush with the outer surface of said outer wall and said bushing is in contact with the sidewall of its respective hole in said outer wall for over at least half the length of said bushing, the remaining portion of said bushing extending from the inlet of said receiving hole into said toroidal chamber. 20. The atomizer wheel of claim 12 in which said wear-resistant material embedded in the surface of said bottom part facing said toroidal chamber extends continuously over said surface between said hub and said outer wall part. 21. The atomizer wheel of claim 14 in which said wear-resistant surface coating on said bottom surface extends continuously over said bottom surface between said hub and said outer wall part.
