Influence of dry and wet ball milling on dispersion characteristics of

Under dry conditions, only particles that directly filled the pots were observed, whereas under the wet conditions, particles mixed with water filled the pots. Accordingly, the wet grinding of the CNTs produced long fiber shapes. During the grinding process, the impact forces of the milling balls are different between the dry and wet conditions.

Ethanol Production

While dry milling is less capital intensive, it also yields less ethanol per bushel of corn than wet milling (Rajagopalan, et al., 2005). Wet milling involves steeping the corn for up to 48 hours to assist in separating the parts of the corn kernel. Processing the slurry separates the germ from the rest of the kernel, which is processed further ...
