What Are the Differences between Dry and Wet Type Ball Mill?

2023年2月15日  The water can wash away the fine particles in time to avoid over-grinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.

The planetary ball milling process is not only mechanically cracking graphitic C–C bonds and edge selectively functionalizing graphitic layers, but also delaminating into graphitic nano platelets. This result is further confirmed from the observation of downshifting (from 2725 cm −1 to 2702 cm −1 ) and broadening of 2D peak.
