    The effects of ball milling on soil health were also studied. Soil structure and aggregation were altered but tillage of the milled soil and mixing it with unmilled soil would create healthy aggregation and the sample soils tested were all able to sustain plant life. The study also looked how soil bacteria would react to ball milling.

  • BACKGROUND REPORT AP-42 SECTION 12

    An example of mechanical cleaning is the dry milling process. Cold aluminum-laden dross and other residues are processed by milling and screening to obtain a product containing at least 60 to 70 percent aluminum. Ball rod or hammer mills can be used to reduce oxides and nonmetallic particles to fine powders for ease of removal during screening.
