Glossary of Mining Terms

Applications. Ball screws are used in aircraft and missiles to move control surfaces, especially for electric fly by wire, and in automobile power steering to translate rotary motion from an electric motor to axial motion of the steering rack. They are also used in machine tools, robots and precision assembly equipment. High precision ball screws are used in steppers for …

Feb 09, 2017· Stoichiometric mixtures of ZnS + Al and ZnS + Mg were milled for different times in a planetary ball mill. The XRD traces of the as-milled samples showed the presence of zinc, MgZn2, and MgS after 30-min milling in the ZnS–Mg system. The traces of MgZn2 disappeared after 1-h milling and the reduction reaction seemed to have been completed after 5-h milling.

May 20, 2020· The strength and deformation behavior of ball-milled, iron-base materials containing nano-scale subgrains have been evaluated. As reported by several authors, nanosubgrains form during the early stages of ball milling as a result of severe plastic deformation inherent in the ball milling process. The strength for these nano-scale subgrains …

Ball Milling. Ball milling machines may be used to reduce particle size, mix or blend materials, or change particle shape. Workers may be exposed to nanomaterials during this process primarily when loading or unloading materials into the ball mills. Witschger et al. [2007] investigated aerosol emissions during the high energy ball milling process.
