A slight difference of condition between the two cases, however, is that with dry milling the fluid (air) fills the whole of the mill shell not occupied by the balls, whereas with wet milling the liquid occupies only a part of the mill volume not occupied by the solid charge. This difference would be expected to have some slight effect on the ...

There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement).

The rock is maintained at about 10 percent moisture and is stored in piles at the mine and/or chemical plant for future use. The rock is slurried in water and wetground in ball mills or rod mills at the chemical plant. Consequently, there is no significant emission potential from wet grinding. The small

In the handling of wet, sticky ores such as encountered in tropical areas having distinct dry and rainy seasons, the crushing plant is a section of the mill which must be planned very carefully. Unless this is done, crushing becomes a constant source of trouble resulting in lost production and high milling cost. In some areas rainfall is high for prolonged periods.

Wet SemiAutogenous Grinding Mills. The primary mill liner task force was formed in 1977. Its function was to improve the operating costs and milling efficiencies of the ten x (27 ft x 18 ft) wet SAG mills that were operating at the time. The SAG mills are driven by two 3500 HP motors drawing a total of 5450 kW at 76% of critical speed.
