8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball …
>One Pot Synthesis of Bio-Ethylene Glycol from Cellulose
Figure 8 shows that the longer ball milling time is, the higher cellulose conversion and EG yield are. The results show that the ball milling time and the amount of functional groups on active carbon play important roles in this reaction. Water is a good solvent. At room temperature, cellulose is not dissolved in water.
