How do you optimize throughput and purity of sodium bicarbonate?

All the soda ash expertise you need

Starting with the first centrifuge shipped to a soda ash producer in 1928, we have been deeply involved in the industry from the very beginning. Since then, we have broadened our capabilities and installed more than one hundred solutions for all of the world’s largest soda ash producers. In fact, the engineers of one of the largest soda ash plants ever built just recently chose ANDRITZ for their complete dewatering and drying line.

The Krauss-Maffei pusher centrifuge, capable of achieving the industry’s lowest residual moisture, is the market-leading solution for centrifugal dewatering in soda ash production. Our advanced engineering expertise and in-depth knowledge of process technologies allow us to support your production in the best possible way – whether you are manufacturing dense ash, bicarbonate, sodium sulfate, or calcium chloride.

Continuous development and support

In the test center equipped with lab-scale centrifuges and full-size equipment, our world-class team of mechanical and process engineers works closely with customers all the time to push the boundaries of innovation. From the world’s highestcapacity centrifuges to the first energy-efficient fluidized bed dryers, we have long been committed to providing new, value-added solutions to support ambitious customers. And as the OEM for reliable brands like Bird, Krauss-Maffei centrifuges, dryers, and filters, KDH Humboldt Wedag, and Escher Wyss dryers, we have the service and automation solutions to help keep you ahead of your competitors for the entire lifetime of your plant.
