Mar 17, 2013 We demonstrate the adsorption performance of nanosized scallop shells prepared by mechanical grinding. The ground shells adsorb formaldehyde vapor up to 1.1 mg g −1, which is a significant improvement in the adsorption properties compared to the feed particles (0.1 mg g −1)

fine bead mill with grinding media on the order of 100 microns (m) to 200 m is the simplest, most scalable, most cost-efficient way to make and disperse nanoparticles, though this too presents obstacles. For example, research shows that when running passes through a media mill, a portion of the batch bypasses the grinding process, short-circuiting through the chamber. This phenomenon is inherent in all fine media
