Typically used to reduce the size of particles in various materials, including minerals, metals, ceramics, and food products. Atritor fine milling processes can generate a mean particle size as small as 20 microns, or less than 510 microns with a combination of deagglomeration and milling.
CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.
The Attritor's design accounts for much of the difference: conventional ball mills turn the entire drum or tank containing the media and the material, while Attritors stir the media in a stationary tank with a shaft and attached arms or discs resulting in a more efficient use of energy for the milling process.
In this work the γ to αAl 2 O 3 phase transformation induced by mechanical milling was investigated as a function of the bead size for two laboratory scale highenergy mills: a planetary ball mill and an attritor mill. The alumina was texturally characterised, before and after milling, by Scanning Electron Microscopy (SEM) analysis, porosimetry by N 2 physisorption with BrunauerEmmett ...
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 highspeed rotating shaft with agitator elements.

top curve represents data from the vibratory ball mill, the middle two curves from the conventional ball mills, and the bottom curve represents the Attritor. At a specific energy input around 100kwh/T, the median particle size achieved in the Attritor () is nearly half that obtained in the conventional ball mill () and about onethird
Ball Mill. For instance, a ball mill, which is a powderprocessing technique involving deformation, cold welding, fracturing, and rewelding of powder particles, is used for mechanical alloying. ... This cylinder is filled with balls that are made of stainless steel or rubber to the material contained in it. Ball mills are classified as attritor ...
Historic tradition. For at least six generations, the local upper and subsequently middle classes, have embraced their Vienna winter balls. Whereas the Imperial ball tradition goes back to the 17th century and Empress Maria Theresa, it was Prince Metternich who ignited the ball fever on a broader level during the Congress of Vienna in ...
Description. Stable isotope techniques can help improve soil management and crop nutrition. To ensure the quality of stable isotope analysis through isotope ratio mass spectrometry (IRMS), appropriate sample preparation is crucial. This publication presents methods for proper plant and soil sample processing for IRMS analysis.
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 (4001,800 rpm) attritors.

The attritor ball mill, also known as stirred ball mill, is a kind of vertical ball mill. It can be divided into dry type and wet type, suitable for grinding a variety of materials, such as industrial ceramics, fireproof materials, silicate materials, metal powder, ores, etc. It is equipped with an agitation system inside the grinding cylinder.
Cryogenic grinding is most effective when the product is sprayed with liquid nitrogen as it is being conveyed and introduced into the Attritor. An additional benefit of cryogenic milling in an internally agitated ball mill is the ability to fully immerse the product in liquid nitrogen during milling. The level of liquid nitrogen in the milling ...
