Test & Development Center

The ROSS Mixing Test & Development Center is a well-equipped facility designed to assist customers by demonstrating the benefits of using the appropriate mixing technology with their products. Located in Hauppauge, New York, the center features a wide range of ROSS mixing and blending equipment, including high shear mixers, planetary mixers, ribbon blenders, and more.

The facility is operated by experienced technicians who work with customers to optimize their mixing processes and achieve the desired results. The center also offers analytical testing services such as, viscosity and density measurements, and particle size analysis to quantify results. With its advanced mixing equipment and knowledgeable staff, the ROSS Mixing Test & Development Center is an invaluable resource for customers looking to improve their mixing processes.

Introducing The ROSS Technical Services Group

ROSS Test and Development Center

The mark of a world class equipment manufacturer is leadership - a company's ability to develop innovative technology, new equipment, and new techniques for making familiar equipment more productive.

That requires a solid commitment to research & development and a clear vision of what process engineers really need to boost production and product quality. The company's R&D effort must be dedicated to development that can lead quickly to significant gains in process-line efficiency.

This is the mission that drives the team of engineers who comprise the new Technical Services Group at ROSS.

We believe that ROSS is really in both the mixing equipment business and the information business.The goal of our Technical Services Group is to manage the information and expertise that ROSS has accumulated over the years. No other company has been in the specialty mixer business longer. No other company has acquired so much front-line experience in such a wide range of industries. Our goal is to make all of that knowledge work harder for ROSS and its customers."

Analytical Laboratory

Quantitative measurement is a critical step in testing. With advanced laser diffraction particle size analyzers and other specialized instruments, ROSS offers its customers excellent accuracy in assessing test results. Especially when the process requires sub-micron emulsification or dispersion, this degree of accuracy ensures that customers are buying the best possible equipment.

"Developing new test methods is a key element in our plan to improve the resources we can offer our customers," says Mr. Langhorn. "By quantifying the mixing process, we can apply our experience much more effectively. Innovation and meaningful progress in equipment design requires a combination of imagination and rigorous analysis."

Research and Development

  • New product development is moving faster than ever at ROSS, and the program is already paying dividends.
  • Recent breakthroughs in rotor/stator generator design have yielded the "X-Series" family of Rotor/Stator Mixers, which produce sub-micron emulsions faster than any other mixer - and much less expensively than high pressure homogenizers or colloid mills.
  • The new PreMax has achieved a similar advance in pigment dispersions. These new mixers can drastically reduce the number of passes needed in a media mill, or eliminate the mill completely.
  • Numerous new devices, like the SLIM Solid/Liquid Injection Manifold and the SISAL vacuum injection system, are accelerating the mixing process and improving operator safety in many industries.

A dedicated design and fabrication shop gives the R&D team the resources necessary to keep the program rolling in high gear. The shop is fully equipped with lathes, mills, and equipment for grinding and polishing. This is where the Technical Services Group develops prototypes for testing new mixers and blenders, and for improving ROSS's current line of equipment.

Technical Publications

Technology in mixing, blending, emulsification and dispersion is advancing quickly at ROSS. Through our newsletters, we are making that knowledge available to the entire community of ROSS customers.

As new application data emerges from our testing program, we prepare application data sheets to share insights with our customers. Although these analyses are strictly limited to information that is not proprietary, they often spotlight processing techniques that are useful throughout our customer base.

Put Our Resources to Work

If you are not already taking advantage of all the experience and expertise ROSS can offer, call 1-800-243-ROSS to discuss your needs with the ROSS Technical Services Group. We will be glad to give you more details on our testing program. We can also provide application information to help make your process operation more efficient, and to improve the quality of your products.

Today, most process engineers consider quantitative testing a critical step in selecting and optimizing mixing equipment. The ROSS Analytical Laboratory is equipped with sophisticated instrumentation, such as a laser diffraction particle size analyzer, to measure particle/droplet size as well as size distribution.

In the ROSS Test & Development Center, customers work with highly-trained lab professionals to simulate their process, test a variety of equipment, and optimize its performance before a purchase is finalized.
