The FEECO Innovation Center is a state-of-the-art testing facility where we can test both agglomeration and thermal processes at batch and pilot scale. Testing your material in the FEECO Innovation Center allows you to gather valuable material and process data. Whether you’re looking to develop a new product, solve a material problem, develop a new process, or even optimize an existing one, our process experts can work with you to develop a customized testing program around the answers you’re looking for.


We can then use the data gathered during testing to scale up the process, as well as engineer and manufacture custom equipment and process solutions, tailored to your exact processing needs.


We offer 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.



We can convert dusts, bulk powders, and sludges into free-flowing pellets or granules for dust-free handling, or to improve product characteristics. We can also test a complete, continuous process with agglomeration, drying, particle sizing, and product recycle capabilities to create a highly efficient process. The FEECO Innovation Center is equipped to test non-pressure (tumble growth) agglomeration and roll compaction (pressure agglomeration).


Through agglomeration testing in the FEECO Innovation Center, we can tell you if your material is capable of agglomeration, which method of agglomeration will best suit your process goals, and what equipment configuration will be required to produce the desired results.


When it comes to choosing a binder, we have a wide selection on hand and have a broad knowledge of binder materials, characteristics, and application rates, so we can help you make the best selection for your material.

The FEECO Innovation Center provides a valuable opportunity to test your material or process in a controlled environment. Some of the many advantages to testing with FEECO include:


Material Experience:

FEECO has been a pioneer in material processing since the 1950s, and has extensive knowledge around thousands of materials and material samples. This experience allows us to better understand your project on both a micro and macro level and deliver a custom processing solution that contributes to your company’s bottom line.


Complete Process Knowledge:

As experts in process design, FEECO is familiar with each aspect of a process, from agglomeration and kiln processing, to drying and cooling, allowing us to look at how the process will function as a whole, instead of each individual portion.


Process Scale-up:

Once the process configuration has been defined, FEECO can aid in process scale-up, as well as manufacturing the custom equipment needed to get the job done.
