With an extensive background in fertilizer production, FEECO has built a reputation for quality, efficiency, and longevity in granulation drums.

We offer various configurations to suit your fertilizer processing needs, whether organic, or inorganic.

Granulation drums work by tumbling material in a rotating drum, typically in the presence of a binder. The binder causes the fines to become tacky and allows them to pick up additional fines, forming agglomerates in a process referred to as coalescence. The tumbling action helps to round the agglomerates and create a homogenous mixture.

Granulation drums are frequently used in fertilizer production, when agglomeration must be combined with a chemical reaction. A pipe reactor can be integrated to increase efficiency where applicable.
