  Ball mill Chemistry Dictionary Glossary

  Oct 20 2018  Ball mill is a grinder for reducing hard materials to powder. The grinding is carried out by the pounding and rolling of a charge of steel or ceramic balls carried within the cylinder. The cylinder rotates at a relatively slow speed allowing the balls to cascade through the mill base thus grinding or dispersing the materials. Type of ball
