Bead mill working principle for dry cement grinding. One crucial characteristic of this mill is the high energy density, 1020 times higher than of a ball mill, and the resulting very compact design. The beadstirring elements on the shaft inside the fixed shell reach a tip speed of 5 times the critical speed.

This (Convertible) and Small Ball Mill is unique in design and is particularly adapted to small milling plants. The shell is cast in one piece with a flange for bolting to the head. In converting the mill from a 30″x 18″ to a 30″x 36″ unit with double the capacity, it is only necessary to secure a second cast shell (a duplicate of the ...

A side by side study: RoM ball and AG mill with F80 around 50 mm and a mill product P80 of around 250um, indicated the OWI is also considerably higher, and although it is known to be biased against finer products, the difference is sufficiently large to indicate that the RoM ball mill is less efficient than AG milling.

You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell Cmodel or equation to get the RPM that corresponds to 75% for that mill diameter.
