Material Testing

The FEECO International testing and tolling facility is a state of the art facility consisting of a pilot plant, tolling production plant, and analytical laboratory. (View our Lab 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.

FEECO offers Bulk Material Handling Lab Testing

We welcome the opportunity to conduct a free “look-see” test on your material. There is no charge for this quick test to verify that your material will agglomerate. We require only one five-gallon pail of material in the state that you would want to process it and a current MSDS. 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.

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.


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. Our agglomeration lab facility is equipped to do roll compaction and non-pressure agglomeration (tumble growth). 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 can develop efficient designs as stand-alone thermal processing units, or complete systems, based around your material. We can meet your high temperature applications with our rotary dryers, rotary kilns, indirect rotary kilns, rotary calciners, and rotary coolers. FEECO’s lab 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. Our lab also has the ability to monitor Oxygen, Carbon Monoxide, Nitric Oxide, Nitrogen Dioxide, Sulfur Dioxide, and combustibles discharged from various thermal processes. We also have the ability to test flight design and pattern using our flight simulator.
