Construction and Components

The cover of the drum is fixed by a knurled screw and a support set, which forces it against a rubber gasket creating thus an air-tight sealing mechanism. 20mm and 25mm stainless steel balls are in the delivery scope. Milling balls of max. diameter of 50mm, from L316 stainless steel or porcelain can also be optionally ordered.

Attached via UGD

The BM-0 Mini Ball Mill has to be attached to the UAM Universal Motor Drive via the UGD Universal Gear Drive. All contact parts of the milling drum as well as the milling balls are made of GMP compliant materials and can be sterilized in accordance with GMP.
