SME EM900135

A SYSTEM HAS BEEN DEVELOPED FOR PRODUCTION OF NEW POWDERED MATERIALS AND FOR MODIFICATION OF PROPERTIES OF EXISTING POWDERED MATERIALS. THE SYSTEM IS CALLED THE ANGMILL MECHANOFUSION SYSTEM AND IT UTILIZES A DEVICE WITH A ROTATING CLOSED OUTER DRUM WHOSE INNER SURFACE IS IN CLOSE PROXIMITY TO A FIXED CURVED PIECE. POWDERED MATERIAL PLACED IN THE DRUM LINES ITS INNER SURFACE WHEN THE DRUM IS ROTATED. WHEN A POINT ON THE DRUM'S INNER SURFACE REACHES THE CURVED PIECE, THE POWDER LAYER IS FORCED THROUGH A NARROW, RESTRICTIVE SPACE. THIS ACTION SUBJECTS THE POWDER PARTICLES TO A NUMBER OF FORCES, INCLUDING COMPRESSION AND SHEAR. BY REPEATING THIS ACTION RAPIDLY AND NUMEROUS TIMES THE POWDER PARTICLES CAN BE MODIFIED. TWO OR MORE DIFFERENT POWDERS CAN BE FUSED INTO A SINGLE POWDERED SUBSTANCE, POWDER FLOWABILITY CAN BE IMPROVED, AND ONE MATERIAL CAN BE COATED WITH ANOTHER. POSSIBLE APPLICATIO
