Ball Mills, Mortar Grinders and various types of Cutting Mills and Beater Mills fall into the Grinding Mills category. Different models within this category can process a wide range of materials, including tough and fibrous materials like plastics, rubber and plant materials not easily reduced with typical crushers and pulverizers. Apparatus for specific tests is also featured here. The Ball Pan Hardness test for activated carbons consists of steel balls as a grinding charge and a specially constructed pan that nests with a sieve stack. The test is performed in the SS-30 Tyler® Ro-Tap™ Sieve Shaker. The Hardgrove Grindability Tester measures pulverization of coal samples as described in ASTM D409
