Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall energy use and media ...

(4) Screening and grinding of refined silica sand. The silica sand with excess moisture removed is screened in a vibrating screen. The silica sand powder under the sieve is sent to the ball mill for grinding until it meets the production requirements. The grinding products are transported to the classifier for classification. When the pass rate ...

Fig. 3 shows a typical TGDTA curve of the silica powder modified by ml of HTMS after ball milling for 24 h. The DTA curve showed two peaks at approximately 130 and 300 °C. The first endothermic peak corresponds to the loss of physically adsorbed and/or hydrogenbonded water from the silica powder [22].The second exothermic peak is ascribed to the thermal decomposition of hexyl groups [11].

Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height (or depth) of charge is measured in the same manner as for ball mill. The size of feed particles to a rod mill is coarser than for a ball mill. The usual feed size ranges from 6 to 25 mm.
