●
High efficiency –
Due to the relatively slow rotational speed but large mass of media, more of the energy goes into
milling and less wasted as heat.
●
Narrow particle distribution –
Solids milled in tumble mills are normally so fine and consistent in size that it’s rare to
require classification.
●
Repeatable results –
Mill operating parameters including rotational speed, media size and milling duration can be
independently controlled with known effect on the final results.
●
Low temperature –
Because of the high efficiency of milling and low heat generation, the solids will not be exposed
to high temperatures. For extremely heat sensitive products, cooling jackets can be provided on the mill cylinder.
●
Chemical containment –
Solids are sealed and contained inside the mill, protecting the environment and operators.
