FEECO Granulation Drums

When it comes to fertilizer processing, our granulation drums (also known as rotary drum granulators) can’t be beat. With over 65 years of experience in providing equipment to the fertilizer industry, 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.

Automated with Rockwell Automation

All FEECO equipment and process systems can be outfitted with the latest in automation controls from Rockwell Automation. The unique combination of proprietary Rockwell Automation controls and software, combined with our extensive experience in process design and enhancements with hundreds of materials provides an unparalleled experience for customers seeking innovative process solutions and equipment.
