This week’s photo illustrates the build-up, or sticking of material in a granulation drum.

Granulation drums, used in the fertilizer industry, can be prone to build-up on the interior of the drum for a couple of different reasons. Often times, the material or binder can have a tacky quality to it, causing it to stick to the interior of the drum, as seen here. Other times, over-spray of liquid binder or water can reach the walls of the drum, creating a surface for material to stick to.

Preventing build-up in a granulator can be done by installing a rubber liner that uses gravity to flex off material as it rotates. Other options include knocking systems that can also be employed to “knock” material off of the drum.

FEECO has been custom building granulation drums for over 70 years. For more information on rotary granulators, contact us today!
