What do re-used bricks and roof tiles have to do with tennis courts?

When processing mineral raw materials, such as stones and earths, gravel and sand or ores, adherent impurities and their reduction or removal play a decisive role. The article “Cleaning process – Study and assessment of the stress parameters applied in the ‘HAVER Hydro-Clean’ high-pressure cleaning system” discusses the cleaning-relevant parameters with the aim of improving material quality and reducing the operating costs.

Core of the investment is a greensand moulding plant, where the processing and mixing of the moulding materials is of particular importance.
Have a lot of interesting insights!
