Conditioning Drums

As the leading provider of rotary drums, FEECO is the industry’s choice for conditioning drums. All conditioning drums are designed around the specific material characteristics and process goals. Conditioning drums are used throughout a number of industries to de-dust and/or polish materials, combine liquid additives with a solid feedstock, and improve material handling characteristics. They are also the device of choice for reagentizing potash in the froth flotation process.


These robust drums work by tumbling material in a rotating drum, mixing both liquid and solid feed components, knocking off granule edges, and applying coating or de-dusting agents and more.
