Fly ash samples were ground by ball mill with a rotating speed of 1200 r/min, a filling ratio of the grinding ball of 25% and a grinding time of 30 min. Fly ash is black after grinding and the carbon particles can be fully dispersed in it. Fly ash samples after ball milling were examined by SEM as showed in Fig. 9.

Small and efficient. Ball Mills are the most effective laboratory mills for rapid batchwise comminution of medium-hard, soft, brittle, fibrous, temperature-sensitive and moist samples down to the finest particle size. The comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside ...
