Grinding and Classification Testing

Grinding equipment at FLSmidth Dawson Metallurgical Labratory includes: laboratory (8x8 inch) ball mills, rod mills and a stirring grinding mill for ultra fine applications. Also available are pebble mills or ceramic mills for specialty products. Our laboratory is currently in the process of adding larger sized laboratory ball mills.

Classification is routinely conducted by settling and decantation over an appropriate sized sieve screen. Other classification equipment includes: a three (3) inch cyclone-pump-and sump combination as well as a half inch cyclone for ultra fine desliming applications. Wet screening laboratory test products or plant samples are routinely conducted for mineralogical, metallurgical or Qem-Scan evaluations. Sized fractions can also be gravity concentrated using a Mozley table with a slimes deck in preparation for release analyses.
