SiO 2 nanoparticles have markedly different properties from those of naturally occurring quartz sand. With large effective surface area, often distinct mesoporosity, and easy functionalizability, they are good dynamic adsorbers and thus already widely used, for example, in medicine, as drug carriers, in polymers, and as carriers of biologically active …

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.

Cleaning and Storing of Ball Mill Charge after the Bond Work Index Procedure is done: Add about 500 g of silica sand into the mill containing the ball charge. Seal the mill. Rotate for 20 revolutions to clean. Empty the mill charge and sand into the ball try once grinding is complete. Clean out the mill using a brush. Put the lid on the mill.
