Clean, safe and fully automatic

SÜLZLE KLEIN GmbH was commissioned by a large steel manufacturer with the development and delivery of two belt filter presses including peripherals. The goal: an environmentally friendly and largely automated blast furnace sludge dewatering system. A central step in steel production is the production of pig iron in the blast furnace. This process produces what is known as gout, a gas/dust mixture containing heavy metals. The sludge produced during the wet separation of fine dust Because of its heavy metal content, the blast furnace gas sludge produced during wet fine dust separation cannot be reused but must be landfilled. In order to make it suitable for landfill and to minimize its volume, it is sludges are usually dewatered by means of chamber filter presses, which require a lot of and cleaning-intensive chamber filter presses. The technical challenges: an extremely abrasive medium and high expectations for availability. SÜLZLE KLEIN was able to meet both criteria without any problems thanks to a specially designed machine technology. It was decided to use two belt filter presses SNP 1800-14-C (with BGT 1500) in conjunction with two solidXfloc T 1500 L polymer plants. The turnkey plant was completed by discharge conveyors, container loading and control unit including installation and commissioning. The new belt filter presses round off SÜLZLE KLEIN’s portfolio of dewatering solutions with the application of blast furnace sludge. The belt filter presses are suitable for almost all areas of metallurgical and steel mill technology.
