The Planetary Ball Mill Pulverisette 5 allows fast and very fine grinding of hard to soft material, dry or in suspension, down to colloidal fineness. It can also be used for mixing and homogenising of emulsions and pastes. Grinding capacity of up to 8 samples per operation.Grinding uses fixed abrasives—the abrasive particles are bonded to the paper or platen—for fast stock removal. Polishing uses free abrasives on a cloth; that is, the abrasive particles are suspended in a lubricant and can roll or slide across the cloth and specimen. A book edited by Marinescu et
