  • Ammonium Sulfate Processing Equipment


FEECO is the leading provider of fertilizer granulation equipment for both inorganic and organic systems. Our custom ammonium sulfate production equipment is relied on by the industry’s most notable players. All equipment is designed around the unique characteristics of ammonium sulfate for optimal processing and handling results.

Material Processing


Our custom granulation drums  are the industry standard for high-capacity, reliable ammonium sulfate fertilizer production. Optionally, a FEECO pipe reactor can be integrated into the granulator for energy savings. We also offer custom pin mixers, disc pelletizers (pan granulators), and pugmill mixers.


Drying & Cooling

Drying and cooling are critical steps in producing a high-quality granular ammonium sulfate that can withstand handling, transportation, and application. FEECO provides the industry’s best rotary dryers and coolers for use in the production of granular ammonium sulfate.



Coatings take granular ammonium sulfate from a standard product to a premium one by reducing dust, decreasing the potential for caking, and improving flowability and handling. FEECO coating drums are the preferred coating device when looking to produce a uniformly coated product.


Bulk Material Handling

FEECO also provides a comprehensive line of bulk material handling equipment for all of your ammonium sulfate handling needs. We offer custom bucket elevators, belt conveyors, reversing shuttle conveyors, and steep incline conveyors, along with pieces to increase the flexibility of your handling system, such as belt trippers and plows, and belt feeders.


We can supply a single piece of handling equipment to fit into your existing process, or a complete bulk handling system as part of an overall process solution.


Plant and Pilot Scale Process Testing and Design

The FEECO Innovation Center is a unique testing facility where we can test your material at both batch and pilot scale in order to work out process variables and design commercial-scale units, as well as scale up the process.


The FEECO Innovation Center is well-equipped to suit a wide range of testing needs, including pelletizing, drying, and roll compaction. We can test on a single piece of equipment, or a continuous process loop.


We offer comprehensive testing services in four categories:

Feasibility/Proof of Concept: An initial, non-witnessed batch testing phase in which the possibility of creating a product is explored.
Proof of Product: A more in-depth batch testing phase in which more time is spent determining whether a product can be made to desired specifications.
Proof of Process: A continuous testing phase that aims to establish the equipment setup and parameters required for continuous production of your specific material.
Process/Product Optimization: An in-depth study to optimize your specific material’s characteristics and/or production parameters in an industrial setting.
