Mechanochemical stabilization of heavy metals in fly ash ...
Compared with fly ash from coal-fired power plants, MSWI fly ash contains a lot of halogen elements, and both dry milling and wet milling can reduce halogen salts. The common point is that after ball milling, SiO 2 increases, CaSO 4 decreases, and no new visible crystals are generated in both the MSWI fly ash and the coal fly ash.

Autogenous Grinding | Article about Autogenous Grinding by ...
If only a small amount of the large fraction is present in the ore, steel balls are added to the mill. In ore-pebble grinding, the ore pebble serves as the grinding medium. In dry autogenous grinding, air is blown continuously through the mill, thus removing the fine material. In wet autogenous grinding, the pulp is removed through a screen.
Wet Grinding VS Dry Ball Mill Grinding
The ore charge in the tests shown in table 18 would probably be small because the mill, which was 19 inches in diameter, had an 8-inch discharge. Wet grinding gave 39 percent, more capacity and 26 percent more efficiency than dry grinding. These values supplement those shown in table 16.
