Mars Mineral designs and builds turnkey systems to convert bulk powder materials into spherical pellets. To develop the pelletizing process for a customer, the company offers research and testing services, including the pilot pelletizing line at the company’s 45,000 ft2 (4,180 m2) production facility in Mars, Pa., near Pittsburgh.
A critical part of the pelletizing process is drying the pellets without altering their size, shape or properties. To provide effective drying with maximum design flexibility, Mars Mineral selected a 30” (750 mm) diameter Vibro-Bed circular fluid-bed dryer, manufactured by Kason Corp., for its pilot-scale pelletizing line used for process development. According to Mars’ General Manager Craig Vaughan, the circular fluid-bed dryer is gentle enough to handle the most delicate pellets and offers advantages over a horizontal fluid-bed dryer, including footprint and cost. As a result, depending on throughput requirements, the company has specified circular fluid-bed dryers for a number of its customer sites.
