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.

For wet FGD it is expressed as a ratio to the SO 2 collected. Typical values would be 1.03 to 1.05 Dry system suppliers express their usage on the basis of the inlet SO 2 . 2. not the SO 2 . 2. collected like the wet systems.

When MC < 8%, the dry process is used. The feedstock is interground and blended in a dry form. For MC between 8 and 15 %, a raw meal slurry (similar to wet process) is prepared, sent through a short kiln with a cyclonic preheater. In the wet process, the feedstock is ground and blended in the form of slurry.

These are the dry and wet concrete grinding methods. The dry concrete grinding method is used to polish concrete, whether it is for floors, walls and countertops or something else.
