Within a few years the process was in commercial operation both in Europe and in North America. For many decades the sulfite process was the leading process for the pulping of wood. Since 1940, however, the kraft process has taken a predominant position, and sulfite mills …
The minimal design of the Attrition Mill creates an optimized flow pattern for material traveling through the unit. Superior engineers decided to draft the tubs with a round design instead of square. This decision allows for consistent sand processing and eliminates the risk of material collecting in square corners.

Union Process manufactures a broad line of particle size reduction equipment such as wet and dry grinding Attritors and small media mills, in laboratory and production sizes. Our particle size reduction equipment is customizable to meet your specific milling and dispersion needs.
Size reduction in attrition mills occurs through the scraping of one surface against another. Particles scrape against each other or against a rigid face. In general, the size of the resulting particles can get near the micrometer level, but in the pharmaceutical industry, demand has increased for particles on the nanometer level.
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).
Sep 13, 2010· These mills use "large" media, ranging in size from 20 mm in diameter and up, to produce material from about ten microns to mesh sizes. Attrition mills are more appropriate for "mid-range" size particles. Such mills utilize 3–10-mm media to produce material ranging in size from approximately 1 to 10 microns.

Jun 20, 2015· If 75 percent of critical speed is considered desirable for efficient grinding in a 2.4 meter (8 foot) diameter mill, then the same will be true for a 5.0 meter (15½ foot) diameter mill.
Attrition mill definition is - a machine in which materials (such as grain or spices) are pulverized between two toothed metal disks rotating in opposite directions.
For large scale production of commercial alloys, attrition mills have been largely replaced by the large tumbler ball mills. Another type of mill that has been used for pilot-size production is the vibratory tube mill. The motion of the balls and particles in a vibratory mill is complicated.
