Immobilization of Pb, Cu and Zn in contaminated soil using

At a milling speed of 500 rpm, and BPR 12, the leaching concentrations of Pb, Cu and Zn decreased with increasing milling time as shown in Fig. 2.The leaching concentrations of Pb, Cu and Zn in untreated soil were 13.92 mg·L 1, 2.71 mg·L 1, and 114.31 mg·L 1, which were 273 times, 2.6 times, and 113 times higher than the Class III level of the Chinese Surface Water Environmental

Optimization of continuous ball mills used for finish

Furthermore, it has shown that a L/D ratio of about 3.0, which is a quite common value for cement mills, might be to high for a ball mill in a Combigrinding plant. This was proven by the fact that there was no grinding progress observed in the last third of the total grinding path length.

Optimization of mill performance by using

to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size from the circuit. Each of these performance parameters peaks at different filling values. In order to continuously optimize mill operation, it is vital to obtain regular measurements of the ball load and pulp position.
