involve grinding). With Lloyd's ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyd's research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.

1 Chapter 17. Processing of Metal Powders 17.1 Introduction This chapter describes the powder metallurgy (P/M) process, in which metal powders are compacted into desired and often complex shapes and sintered (heated without melting) to form a solid piece. This process first was used by the Egyptians in about 3000 B.C. to iron tools. One of its first

The mill scale is ground, magnetically separated and first roasted in air to convert the Fe3O 4 to Fe 2O 3 because the rate of reduction of Fe 2O 3 with hydrogen is faster than that of Fe 3O 4. ... These hydrides are quite brittle and can be readily ball-milled into powder of the desired ...

Spherical powder of the aluminium alloy AA2017 (grain fraction > 100 μm) was used as matrix material. SiC and Al 2 O 3 powders of submicron and micron grain size (< 2 μm) where chosen as reinforcement particles with contents between 5 and 15 vol.% respectively. The high-energy milling process was realised in a Simoloyer mill (Zoz).
