Raymond® and Bartlett-Snow™ Research and Process Development Center

Naperville, IL USA

Testing Resources

Our 25,000 square foot pilot plant facility is used exclusively to test and demonstrate the capabilities of Raymond® and Bartlett-Snow™ equipment under simulated production conditions. This facility houses a wide range of full-scale processing equipment capable of grinding, classifying or thermally processing virtually any mineral, chemical, food or other material. Equipment is also available to perform pre- and post-processing chemical and physical analyses.

We test large material lots on full-size equipment to reduce much of the uncertainty of scale-up between bench and full-scale equipment. Managing large production quantities of test materials often uncover handling difficulties and other problems that might otherwise be overlooked.

You will work closely with our experienced engineers and technicians to simulate the environment of your operations as closely as possible. After the test, you’ll receive a computerized, analytical report, as well as our recommendations for equipment to best address your application.

Our research and development staff can perform computational fluid dynamics (CFD) computer simulation for many different types of processes, contributing to our ability to understand the application. For example, CFD analyses have been conducted on dynamic classifiers to optimize design. New product innovations are conceived, tested and developed at our facility before release to our customers.
