Material Testing

The FEECO Innovation Center is a state of the art testing facility consisting of a pilot plant and analytical laboratory. (View our Brochure)


The pilot plant can be set up for testing on a single piece of equipment, or multiple pieces of equipment as a continuous process loop. With over 60 years of testing experience, we’ve built a vast database on a variety of materials and test procedures. We can use our experience to help you make informed decisions on process design and process optimization.


We require only one five-gallon pail of material in the state that you would want to process it and a current MSDS for initial feasibility testing. We would also seek your input as to material characteristics such as size, strength, and density you would require in a final product. We can select the most appropriate technology and conduct the testing for you. If you have specific ideas regarding the process development, we would value your input.


Our state of the art agglomeration capabilities can provide solutions to your fine material needs. We can convert dusts, bulk powders, and sludges into free-flowing pellets 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 roll compaction and non-pressure (tumble growth) agglomeration. We can custom make disc pelletizers, rotary drum agglomerators, pin mixers, paddle mixers / pug mills, roll compactors, and briquetters to suit your agglomeration needs.


We have a broad knowledge of binder materials, characteristics, and application rates. We also have a wide selection of binders on hand for establishing the most cost effective concentrations to use for your material.


We can develop efficient designs as stand-alone thermal processing units, or as complete systems, based around the processing needs of your material. We can meet your high temperature applications with our rotary dryers, rotary kilns, indirect rotary kilns, rotary calciners, and rotary coolers. The FEECO Innovation Center has tested a variety of thermal processes, such as calcining mined materials, disposal of restaurant cooking waste, and separation of precious metals from undesirable products. We also have the ability to monitor Oxygen, Carbon Monoxide, Nitric Oxide, Nitrogen Dioxide, Sulfur Dioxide, and combustibles discharged from various thermal processes. We also have a unique flight simulator that allows us to test both flight design and pattern.
