A two-component dust binding system from NEBOLEX Umwelttechnik GmbH was installed and successfully commissioned at a scrap cleaning plant in Peru, South America.

The aim is to separate the fines, such as dust and impurities, and thus improve the quality of the steel scrap. NEBOLEX Umwelttechnik GmbH installed armored spray bars with integrated mist nozzles close to the source of the dust at all points where conveyed material falls or is dropped. The particularly robust design of the stainless steel bars ensures that unexpectedly heavy scrap parts cannot damage the protected fog nozzles on contact. The two-substance system consisting of the media air and water can also nebulize filtered process water through the special nozzles. The control of the spraying system is integrated into a control cabinet. Only when material is present does the fogging switch on automatically.

After passing through the special scrap screen, the screened scrap is virtually dust-free and has convinced the customer. The targets in terms of capacity and required scrap quality were achieved and even increased. This is essential as the cleaning system is installed in a hot and dry area. High dust levels mean higher environmental pollution. The successful water spraying system ensures maximum dust binding, which conserves resources.
