Caption: Using an industrial drill during the fabrication of a ball mill, Sheffield, South Yorkshire, 1963. An engineer using an industrial drill during the fabrication of a ball mill at the Edgar Allen Steel Co in Sheffield. Ball mills are used to grind or mix materials like ores, chemicals, ceramic raw materials and paints. They rotate around a horizontal axis, partially filled with the material to be ground plus the material that does the grinding. This can be ceramic or stainless steel balls, flint pebbles or similar materials. The cascading effect reduces the material to a powder.
