The ball mill, a type of grinder, is a device used to grind materials like ores, chemicals, ceramics and paints. The ball mill may rotate around a horizontal axis, a vertical axis, or an axis inclined between the horizontal and the vertical, partially filled with the material to be ground in addition to the grinding medium.

for M = Ca, Mg, Al ( "d χp). The 1st dehydrogenation temperatures of the samples (M = Na, Li, Ca, Mg) were 10‒20 °C lower than that of AB itself (χp "d ). The amount of NH3 was decreased as χp increased. On the other hand, the amount of B2H6 was decreased as χp decreased. The emission of B3H6N3 could occur by the reaction of NH3 and B2H6.
