For regrind the vertical mill is already a consolidated reality scale-up purposes in the same way as the batch tubular ball mills and it is being applied for most new process flowsheet designs. It are used for scaling-up industrial ball mills. However, due to its geometry, the size of the ball charge of the laboratory vertical mill must also be
Tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a grinding process. Like ball mills, grinding (steel) balls or pebbles are often added to stirred mills to help grind ore, however these mills contain a large ...
