Crushed between the bowl wall and the pestle by manually pushing the pestle or spinning the bowl with a fixed pestle in an automated system. ball, pebble and rod mills are rotating cylinders that are partially filled with metal or ceramic balls, flint pebbles or rods. the units are capable of producing very fine powders, such as nano.
Ing equipment. he proposed j = 35 % as optimal ball fill-ing volume for cement plants. on the other hand, metzger m.j. et al. () using silica sand as a test material showed that the lower the ball filling j the higher is the amount of the produced product. they also found that more efficient breakage occurs at ball filling volume j = 1.5.
