This photo of the week shows the inside of a coating drum while in operation at the FEECO Innovation Center.
Coating pellets is desirable for many reasons, including to control dust, caking, or moisture absorption, or to improve flowability of a material. Coatings are also used in products such as fertilizers, where a controlled release of ingredients is required. Additionally, coatings can help preserve the integrity of a pellet product.
How a Coating Drum Works
As can be seen in the photo, pre-made pellets are fed into one end of the rotating drum, and the coating material is sprayed onto the bed of pellets (not shown in image). As the drum rotates, the pellets pick up the coating, and the rolling action helps to agglomerate the coating onto the exterior of the pellets.
Using our state-of-the-art Innovation Center, FEECO can custom engineer a coating drum to suit the needs of your material. For more information on our agglomeration capabilities or testing options, contact us today!
