FMC Technologies' Roto-Louvre® and Roto-Shell™ coolers are effective, rugged, and exhibit low maintenance and operational cost when drying abrasive, hard, metamorphic rock-minerals, such as quartzite.
The design and construction materials provide strength and rigidity when conveying abrasive materials, especially when the product requires high temperatures to remove moisture.
The internal design of the Roto-Louvre and Roto-Shell evenly distributes hot and/or cold air throughout, as well as conveys the product to ensure that the product exits the unit to customers requirements and specifications such as moisture content, product discharge rate and temperature.
