may 22, 2019 therefore, in the rolling ball mill, the grinding efficiency is increased as the ball diameter decreases. It has been proven that the highest grinding efficiency can be obtained with a small ball of .mm diameter. however, the ball diameter is too small to wear too fast, and it is also difficult to discharge due to the small gap of the ball.
the wastewater from the mill is first prescreened with drum screens; then it is sent to an equalization basin, from which it is pumped directly into the bioreactor. the mbr process decreased the cod from 4000 mgl to less than 200 mgl and the bod from 1700 mgl to less than mgl. permeate is partly recycled as process water.
