The manufacture of various products, such as paving stones or block steps, in a natural stone factory is associated with considerable dust generation. The company was obliged by the authorities to reduce dust emissions to a minimum during the open-cast mining work and processing of the material. To prevent further inconvenience, Nebolex Umwelttechnik GmbH was commissioned to bind the dust.

After an on-site inspection and careful planning, the practical implementation began. During the demolition (blasting), several mobile dust binding machines were used to prevent the dust from spreading in the quarry. Dust binding during the further processing of the material in the crusher was ensured by spray bars attached directly to the dust source. The robust design of the stainless steel strips with integrated mist nozzles also allows them to be used in harsh environments. The nozzle technology used can easily nebulize dirty water, i.e. screened surface or cistern water. Neither small impurities nor a high lime or salt content pose a problem for dust precipitation.
