Mechanochemical stabilization of heavy metals in fly ash from coal
The ball milling experiment was set at a speed of 700 rpm for 2 h, 4 h, 6 h, 8 h and 10 h. The ball mill would stop running for 5 min every half hour to prevent the high temperature from impacting the mill performance (Sun et al., 2011). The long-term ball milling experiment was designed to observe the effect at various time points.
