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 to assist in your R&D efforts. 

Testing 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 optimize an existing one, our process experts can work with you to develop a customized testing program around the answers you need. We can also generate small samples of product for field trials and further testing.

We use the data gathered during testing to scale up the process and manufacture custom equipment, tailored to your exact processing needs.

Bulk Solids Process Development & Optimization for the Fertilizer, Mining, and Chemical Industries

Equipped with unmatched expertise and an extensive array of process equipment, the FEECO Innovation Center is an essential resource for producers looking to develop a process to dry, thermally treat, mix, condition, or agglomerate/granulate their bulk solids. Coating of granular products can also be tested.

The Innovation Center serves nearly every industry, handling a wide range of materials. We regularly test:

  • Adsorbents
  • Animal feed products
  • Carbon products
  • Catalysts
  • E-waste and metal recovery applications
  • Fertilizers (NPK, Potash, MAP, DAP, Phosphates, etc.)
  • Industrial by-products (EAF Dust, Cement Kiln Dust, Fly Ash, Syn Gyp, etc.)
  • Manures and animal bedding
  • Metallic ores and compounds
  • Pulp and paper residuals (paper sludge, etc.)
  • Soil amendments (Limestone, Gypsum, Compost, Recovered wastes and by-products, etc.)

Process Development Stages

Depending on the testing objective(s) and what is already known about the material, testing is typically conducted in the following stages:

Confirm Feasibility (Proof of Concept)

The Innovation Center can confirm feasibility and establish proof of concept of an intended process through batch-scale testing. This type of testing typically consists of an initial, non-witnessed test that explores the possibility of creating a product from a representative sample of the source material. From this, producers can gain an understanding of whether or not the intended process merits further exploration on a larger scale.

Proof of Product 

Proof of product testing consists of a more in-depth batch test in which more time is spent determining whether the source material can be made into a product that meets the desired specifications.

This may include exploration of various binding agents, equipment configurations, pretreatment requirements, as well as other process and equipment variables that influence end product specifications.

Proof of Process

Proof of process testing consists of continuous testing in our pilot plant. This pilot-scale testing aims to establish the viability of the intended process on a continuous basis, as well as the equipment setup and parameters required.  

Process/Product Optimization

Once proof of process has been established, testing moves on to process and product optimization. This stage consists of in-depth testing in our pilot plant, with tests designed to optimize product quality and process efficiency for commercial-scale production. 


From testing on a single piece of equipment, to a continuous process loop, we offer a variety of equipment types, as well as support equipment to cover the full range of process testing needs. In addition, we are capable of making on-site, large-scale modifications to our facility in order to accommodate your bulk solids testing needs.

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 Testing Experience:

FEECO has been a pioneer in material processing since the 1950s, with in-depth knowledge around thousands of materials. Because of this, we are often able to expedite the testing process, with an understanding of what typically works and what doesn’t. 

Complete Process Knowledge:

As experts in process design, FEECO can offer expertise not only in each step in the process, but also in how the process comes together as a whole. This allows us to better understand your project on both a micro and macro level.

Process Scale-up Capabilities:

Once the process configuration has been defined, FEECO can aid in process scale-up, as well as manufacturing the custom equipment needed to build the commercial-scale plant.


The FEECO Innovation Center has helped companies around the world to transform various wastes and process by-products into value-added products through agglomeration and thermal processing methods.
