Two mills were used to produce the regolith powders of different reactivities. One was the same roller ball mill (Labmill-8000) that was used in prior research . The powder was milled in an alumina-fortified porcelain jar with cylindrical (diameter 1.27 cm, height 1.27 cm) alumina grinding media at 200 rpm for 2 h.

Granular α‐Al 2 O 3 samples were ground manually (referred to as "pestled") prior to grinding in a planetary ball mill (PM 400, Retsch , Haan, Germany). Pestled powders were milled for 30 min with distilled water and 60–70 alumina grinding balls with a diameter of 10 mm; the grinding container accommodates a total volume of 150 mL.

Thus, the medium could be steel or cast iron balls when the mill is designated as a ball mill, or it could be steel rods where the mill is known as a rod mill. When no grinding medium is charged it is known as an autogenous mill. In this chapter, we initially discuss the design and operation of tubular mills followed by ball mills.
