Read OnDry crushing but wet grinding. Crushing is usually a dry process, while milling is performed with water. The advantage of wet milling is the lower energy input compared to dry milling. Additionally, some chemical reagents can be used to minimize the energy consumption of grinding, because grinding energy is minimum at pH of the point of zero ...
Read OnDry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.
Read OnBy comparing the plots of the remaining mass (%) fraction vs. grinding time obtained using different f c values (Figure 3a–c), it appears that for a certain grinding time, lower f c values result in a smaller amount of material which remains in each particle size.
