Types of Mills

Mechanical alloying for commercial production is carried out in ball mills of up to 3000 lb capacity (Fig. 5). The milling time decreases with an increase in the energy of the mill. For example, a process that takes only a few minutes in the SPEX mill can take hours in an attritor and a few days in a commercial mill.

Cryo Milling | Cryogenic Grinding

The introduction of lower temperatures during cryomilling curbs recrystallization and embrittles materials so they can be fractured more easily with mechanical milling. Cryogenic grinding is often performed in impact mills and hammer mills, but the use of an internally agitated ball mill, like an Attritor, can provide additional benefits.
