Get PriceWet grinding of hard minerals is usually much more efficient than dry grinding. When slurry is dried in the kiln, it forms a granular crumble that is ideal for subsequent heating in the kiln. In the dry process, it is very difficult to keep the fine powder rawmix in the kiln, because the fast-flowing combustion gases tend to blow it back out again. It became a practice to spray water into dry ...

Get PriceDry cleaning is any cleaning process for clothing and textiles using a solvent other than water.The modern dry cleaning process was developed and patented by Thomas L. Jennings.. Dry cleaning still involves liquid but is so named because the term 'wet' is specific to water; clothes are instead soaked in a water-free liquid solvent, tetrachloroethylene (perchloroethylene), known in the industry ...
Get PriceHeat imparted to the material, due to the work of grinding, is related to the time it is held within the chamber and the air flow characteristics. Impact grinding is most efficient with dry, low-fat ingredients, although many other materials may be reduced in size by proper screen selection and regulated intake.
