New ANDRITZ screen scroll centrifuge increases uptime and product quality


International technology group ANDRITZ has developed a new screen scroll centrifuge with innovative features that reduce wear, enable the rapid exchange of parts, and increase maintainability.

The new ANDRITZ screen scroll centrifuge HX can process bulk chemicals, minerals, agrochemicals, and food, even under difficult feeding conditions. It is designed for improved product quality and maintainability. New features include a Gentle Feeder™ feeding system, a modular scroll, and a rotating assembly that can be removed and replaced in one piece (express cartridge).

The express cartridge design enables the entire rotating assembly to be replaced without dismantling any process piping, reducing downtime to less than eight hours, even for major maintenance work. Minor maintenance work can be done without removing the cartridge as the scroll and screens are easily accessible and removable. The scroll itself is a modular unit designed specifically for cost efficiency and rapid repairs – worn parts can be replaced separately using standard tools. These new features minimize maintenance costs and maximize uptime.

The screen scroll centrifuge HX is also equipped with ANDRITZ's proven Gentle Feeder feeding system. It gently accelerates the solids, thus reducing particle breakage and screen wear. An automated cleaning-in-place system, a cake washing feature and optional additional wear protection round off this innovative solution.
