In the milled powders, the W peak was maintained after 14 h of milling, but the Cu peak broadened after 12 h and almost levelled out after 14 h. The sintering was carried out at the temperature of 1150˚C, and relative sintered density of 67%, 98%, 97% and 94% TD was obtained from powders milled for 0, 8, 12 and 14 h respectively.
Powder metallurgical processing of MMC (see Chapter 3.25 this volume) sharply reduces the danger of interfacial reaction occurring. Any MMC scrap (discontinuously or continuously reinforced, and irrespective of reinforcement content) can be milled to powder (or machined to chips). This may serve as raw material for secondary MMC-powder ...
Wax can also be precipitated out of solution. Prior to Shamrock's development of micronized wax, a coarse powder was ball milled for liquid inks. For paste ink, the wax was dissolved in a hot resin solution, typically in a large tub over an open gas burner, and poured onto a 3 roll mill to precipitate fine crystals, hopefully or artfully.

5, The fineness of requirements of the grinding material The finer the fineness requirements of the milled material, the lower the yield, and the vice versa, the higher the yield. For some areas, over-emphasis on fineness is not in line with economic production requirements.
The fineness of the milled product, when using the plate, or stone attachments, can easily be adjusted with the adjustment wheel on the side of the machine - which adjusts the gap between the two plates. The pin mill however is not adjustable as the fineness is determined by the speed of the pins and the spacing of the pins.
