the function of the attrition mill - PELOT

An Attrition Mill is used forreducing “no bake” bottom sand lumps to “grain size” of minus 20 mesh or green sand to small particles.Sand is dumped into the rear hopper section. The lumps rub on one another and produce “fine” grains which can convey up a steep incline. A screen deck near the discharge end removes the grain size sand and discharges it to the side.

Attrition mill operating characteristics - ScienceDirect

1975-7-1  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 sustained transportation of particles in a suspension commonly results in particle attrition leading to grain size reduction and shape modification. Particle attrition is a well-studied phenomenon that has mainly focussed on sediments produced in aeolian or fluvial environments. Here, we present analogue experiments designed to explore processes of attrition in the kimberlite system; we ...
