Vertical agitated dry media mill

A vertical agitated media mill is used for grinding ultrafine particles, in an agitated (or stirred) grinding media action, such as mineral fillers, glazing raw materials and non-mineral hard materials. It comprises a cylindrical grinding chamber that is filled with grinding beads of a few millimeters in diameter.

Ideal for mineral fillers, glazing raw materials and non-mineral hard materials

The ATR vertical agitated media mill from Hosokawa Alpine is a vertical agitated media mill that comprises a cylindrical grinding chamber, with a double-walled mill housing to permit water cooling, that is filled with grinding beads of a few millimeters in diameter.

Because of the small grinding beads, the particle size of the feed material should not exceed 100 µm. The agitator shaft with its arms dips into the bed of material and grinding beads and is set into slow rotation by a gear unit connected to a motor.

Typical used for milling mineral fillers, glazing raw materials, and non-mineral hard materials. Examples: limestone, quartz, zircon sand, talc, ceramic colors and frits, titanium dioxide, etc.
