The present invention provides a system for treating powder materials, such as fly ash, cement, slag, or the like, and a method of use thereof. The material treatment system facilitates the application of a desired chemical entity to the material passing through the system. The material treatment system disclosed herein is capable of performing this task while the material is moved at a high velocity. The system includes a fluidized bed chamber, discharge chamber, application chamber, and concentration chute. The result is the quick and consistent application of a chemical entity to the material so that the treated material has the desired characteristics.
