Testing Services for Particle Reduction and Air Classification

HANOVER, MA – In addition to manufacturing size reduction and air classification equipment, Sturtevant offers testing services at their fully equipped facility in Hanover, MA. The process equipment available within the facility includes jet mills, air classifying mills, pin mills, jaw crushers, roll crushers, disc mills, hammermills, and air classifiers. With these options, qualified laboratory technicians are able to process dry solids from 1/4″ to 0.25 microns so customers can evaluate and determine the best way to achieve fine particle sizes, validate product expectations, and confirm economic feasibility.

The process of requesting a test from Sturtevant can be started on their website here by completing a Request for Information form. To ensure the material can be safely processed and tested at the facility, a Material Safety Data Sheet also has to be completed. In the case that Sturtevant is not properly equipped to handle the material, alternatives available will be provided for the Bill_edited-croppedmaterial or application.

Once scheduled, customers have the opportunity to visit the facility and benefit from hands-on experience, equipment operator training, and technical presentations. Bill Chapman, Lab/Service Manager for Sturtevant, explains that witnessing tests in person “adds valuable insight into the machine and its capabilities.” Whether a customer is able to visit the facility or not, laboratory technicians provide key observations such as wear protection requirements and material handling recommendations. Given the diversity of materials tested, the laboratory is equipped to measure low micron powders with a wet/dry laser analyzer, fine powders with wet/dry sieves, particle shape with micropsy, blaine/surface area, bulk density, and moisture content.

Data derived from testing, and provided to the customer, can be used to scale-up to production equipment and give performance guarantees. Customer confidentiality is maintained throughout the testing process and any exchange of proprietary information.
