PSRI has over 160 years of experience and over 225 reviewed publications in fluidization and particle technology.

PSRI works with hundreds of clients from all over the world in such industries as petrochemical, chemical, pharmaceutical, agricultural, power and energy, mining, food processing, and semiconductors. Chances are we have already seen your problem and know how to drive your success.

We don’t stop at solution space. We believe that training is an important part of maintaining success. Thus, PSRI offers intensive fluidization seminars all over the world, provides design manuals, procedures, methods, and webinars. PSRI believes that giving someone a fish is not as good as teaching someone how to fish.
PSRI has state of the art facilities to do research on an industrial scale. As a result, PSRI’s research is relevant to your problems and your bottom line. That is because wall effects matter, pressure effects matter, and temperature effects matter. With PSRI’s research, the data is relevant and applicable.

Particulate Solid Research Inc. (PSRI) is an international consortium of companies focused on the advancement of technology in the multiphase flows with granular and granular-fluid systems. Since 1971, PSRI has amassed a prolific amount of design data, technology, know-how, design criteria and models on all aspects of slurries, liquid injection, fluidization, entrainment, pneumatic conveying, attrition, erosion, distributor design, standpipes, solids transfer, and circulating fluidized beds.  From the data produced, PSRI has developed design correlations, models, procedures, methods and techniques which are among the best and most useful in the field.
