The extent of attrition associated with impact loading was studied for five different limestones pre-processed in fluidized bed under different reaction conditions. The experimental procedure was based on the measurement of the amount and the particle size distribution of the debris generated upon impact of sorbent samples against a target at …

How Circulation Attritors Work The circulation grinding Attritor ("Q" machine) is a combination of an Attritor and a large holding tank which is generally about ten times the size of the Attritor. The unique principle of the "Q" Attritor is the high circulating (pumping) rate, which results in a faster grind and a narrower particle

The ball mill is a rotating cylindrical vessel with grinding media inside, which is responsible for breaking the ore particles. Grinding media play an important role in the comminution of mineral ores in these mills. This work reviews the application of balls in mineral processing as a function of the materials used to manufacture them and the …

The attrition mill is a device for mechanically reducing solid particle size by intense agitation of a slurry of material being milled and coarse milling media. For example, in 10 hours of milling, specific surfaces of 40 and 25 m 2 /g were obtained for alumina and barite, corresponding to 38 and 56 nm equivalent spherical diameter, respectively.

The attrition mill utilizes an adjustable output 3 phase vibrator which is bottom mounted to provide maximum agitation of the sand mass. Vibrator horsepower ratings for the R-1, R-3, R-5, and R-10 are 2, 4, 5, and dual 5 horsepower, respectively. The attrition mill includes as standard a three sided tapered load frame to aide in loading efficiency.
