Stirred mill technology dates back to 1928 where the idea to use "an agitator and spherical grinding media" was presented. The year 1948 saw the successful application of DuPont's "sand mill" for pigment grinding. Subsequent years have led to the development of different types of stirred mills spanning
Stirred bead mills find application in a number of industries where there is a need for very fine grinding or particle dispersion. In the minerals industry this type of mill is becoming increasingly important due to processing of ore bodies which are fine-grained and require milling to fine sizes for effective mineral liberation.
Stirred milling technology is employed in mining processing to grind particles down to fine and ultra-fine particle sizes in a wide range of mining application. Stirred mills convert electric energy provided by a high torque motor to kinetic energy to the grinding media. The ore particle size reduction is resulted from the high collisions and ...
