The EMS Energy Institute houses equipment for size reduction and classification of coal and biomass, and coal-water mixture (MCWM) preparation. These facilities are used to prepare coal, biomass, or CWM samples that range in quantities from grams to barrels for fundamental and applied research.

The equipment ranges in size from bench-top units to large pilot-scale facilities. Historically, the facilities were installed to clean coal, dewater fine coal streams, or crush, pulverize, or process coal into CWM for combustion/gasification/emissions studies. In addition, some of the facilities are used for preparing biomass samples for analysis and testing.
