COATING DRUM APPLICATIONS
Coating drums are extremely flexible and can be used to apply most types of coatings to particles, be it for de-dusting, anti-caking, or otherwise.
Common applications for coating drums include:
- Granular Fertilizers (MAP, DAP, Urea, NPK, Ammonium Sulfate, TSP, SSP)
- Granular Animal Feeds (MCP, DCP)
- Proppants
- Cat Litter
- Chemical Powders
- Iron Ore
