Ball milling method. By mixing fly ash with CaO and placing in ball mill system, mechanochemical treatment can achieve great dechlorination and the main products are biphenyl and chloridion. Biphenyl can transfer to terphenyl, quaterpheny, cyclohexylbenzene and bicyclohexyl through the polymerization and hydrogenation reactions.
To determine the power that a dry grinding needs, full grate discharge mill Equation 1 is multiplied by the factor of 1.08. A multi-compartment ball mill consists of two or more grate discharge ball mills in series. The same equation is used to calculate the power that each ball mill compartment should draw. The total power is

The overflow mills use much simpler trunnion bearings to support the mill, whereas grate-only discharge mill would require a tire gear around the shell which is expensive and involves complex manufacturing process as the grate has to withstand the pressure exerted by the steel ball charge and allow slurry to discharge effectively."
For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill…
