Mar 31, 2008 · Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers, allowing the use of different sizes of grinding media. Large balls are used at the inlet, to crush clinker nodules (which can be over 25 mm in diameter)

Example - Chimney Draft. A 20 m high chimney operates with flue gas temperature 200 °C (473 K). The outside temperature is 0 °C (273 K). The density of the outside air is 1.292 kg/m 3. The draft in the chimney can be calculated with (3) as. dp ch = (20 m) (1.292 kg/m 3) (1 - (273 K)/ (473 K)) (9.81 m/s 2) = 107 Pa. Chimney Draft Calculator. h
