New Developments in Attritors. The attritor, or stirred ball mill, is a grinding mill containing internally agitated media. There are quite a few types of attritors; they can be categorized as dry grind, wet grind, regular speed (to 400 rpm) and high speed (400–1,800 rpm) attritors. A useful and simple equation describing the grinding ...

For example, ball mills use large media, normally 1/2" or larger, and run at a low (10-50) rpm. The other mills, such as sand, bead, and horizontal, use smaller media (from 1/64" to 1/8"), but run at a very high rpm (roughly 800-1200). High-speed dispersers with no media run even faster (1200-1800) rpm, with tip speeds of 5000-6000 fpm.

Attritors can be found in many sizes and a variety of places, from small scale laboratories or pilot plants to factory production floors. Attritors, also referred to as stirred ball mills, work by use of 'shear' and 'impact' methods on a given material by another stronger media.

Vibratory action exposes the casting for removal, breaks down sand and creates the attrition for reclaim sand. Screening of the reclaimed sand provides a grain size material for reuse. #8 and #12 mesh screens provided as standard. Low head-room design does not require pits. Attrition is based on GK's proven VIBRA-MILL® technology.

The SDG Attritors use grinding balls from 5mm to 13mm. The shaft RPM generally runs from 75 to 500. This series of Attritors are suitable for harder-to-grind materials such as metal powder, metal carbides, and glass chunks. The feed material size for these machines can be quite coarse, but smaller than the grinding media chosen.

Attrition mills effectively mill metals in inert atmospheres, such as in solid-state or mechanical alloying processes, but are not cost effective. Product output is relatively low with attrition mills, compared to large tumbler and vibratory ball mills. Consequently, tumbler ball mills usually are used for production runs of over 135 to 180 kg ...
