If you think the differences between dry and wet screen mining are limited to the presence or lack of water, then you're missing several important points. First of all, wet separation technology requires additional equipment, including the spray nozzles that funnel the water. Extra plant capital is on the agenda when these additional stages enter the equipment line.

Some of the media falls and impacts the ore particles at the bottom of the mill. The rest of the media cascades and, in the process, creates particle breakage by attrition. The process is continuously repeated as the particles move by mass and volume action through the mill. Dry and wet grinding common.

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.

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.

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.
