Laboratory Testing

Sturtevant’s fully equipped test facility in Hanover, MA is capable of processing dry solids from ¼” to 0.5 microns. Relying on Sturtevant’s years of experience, customers can evaluate and determine the best way to achieve fine particle sizes, validate product expectations and confirm economic feasibility.

Qualified laboratory technicians optimize equipment capacity and provide valuable observations, such as wear protection requirements and material handling recommendations. The data derived is used to scale-up to production equipment and to provide performance guarantees. Short-term contract manufacturing is available while equipment is being manufactured.

The process equipment in the test facility includes jet mills, air classifying mills, pin mills, jaw crushers, roll crushers, disc mills, hammermills and air classifiers, using variable speed controls. In addition, the lab is equipped to measure low micron powders with a wet/dry laser analyzer, fine powders with wet/dry sieves, particle shape with microscopy, blaine/surface area, bulk density, and moisture content.

Customers who take the opportunity to visit the facility benefit from hands-on experience, equipment operator training and technical presentations. Customer confidentiality is maintained throughout the testing process and the accompanying exchange of any proprietary information.
