velocity), which enables us to see how the Attritor fits into the family of mills. 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 0.3mm to 2mm, but run at a very high rpm (roughly 800-1200).
Grinding behavior of nanoparticles in an attritor mill and the minimum achievable particle size are strongly influenced by the suspension stability. In the present work, suspension stability (i.e. ζ-potential) of nanoparticles was studied by measuring pH as a function of grinding time in the wet milling process. It was found that after a ...
Earlier investigators have utilized attritor mills and wet milling (slurry of metallic powder with liquid nitrogen) to prepare metallic nanoparticles. Zheng et al. [12] have reported that it is possible to reduce the particle size of Mg alloy (AZ80) from 55 μm to 10–30 μm after 8-h cryomilling while average grain size is reported to be 40 nm.
Buhrstone mills: The oldest of attrition mills, Buhrstone mills are still used today for wet milling corn and whole-grain flour. Planetary mills: As a subcategory of ball mills, planetary mills are used primarily for reducing sample material in laboratories, though they are also used for mechanical alloying.
It was found that by increasing the nanoparticles content, the hardness and strength of the composites first increased and then decreased when the amount of the nanoparticle exceeded 4 wt.%. ... Ball-milling of graphite was carried out in attritor ball mill at room temperature in hexane medium for different times i.e. 24, 48 and. The self ...
An attritor mill, also known as a stirred ball mill, is a type of milling equipment used for grinding materials into fine particles. It is characterized by its unique working principle, which involves a high-speed rotating shaft with agitator elements. The agitator elements consist of impellers or discs that are mounted on the shaft and rotate ...
Attrition Mills from Munson Machinery are ideally suited for reducing fibrous and friable materials within a relatively narrow particle size range from coarse down to 100 mesh.

Bead mills and attritor mills are both used for grinding and dispersing materials down to fine particle sizes. Bead mills work by agitating a mixture of the material to be ground and a grinding medium (beads) with a rotating agitator. This causes the beads to collide with the particles of the feed, breaking them into finer particles.
Polymer nanoparticles and nanocomposites are of great interest for the manufacturing of nano- and microstructured materials and have been studied extensively throughout the past several years. However, in contrast to ceramic particles, relatively little is known about the milling behavior of polymer particles in stirred media mills.
