Improved sand quality for Reddal Sand
A new sand washing plant for Reddal Sand has resulted in a significant improvement in the quality of the sand being produced at their site in the South of Norway. Reddal Sand is located in Grimstad, Aust-Agder and has supplied a variety of construction materials to major projects in the area since 1989. These include materials for use in the manufacture of roofing tiles, concrete, road construction and various types of groundworks including sports fields, playgrounds and golf courses.
Morten and Jan Tore Pedersen of Reddal Sand began looking for suitable wash plants as they believed they could recover more material than was currently the case from the sand and gravel reserve. A particular area of concern was the top 3 to 4 metres of the deposit which contained a high level of fines and clay contamination that was compromising the final quality of their sand product. After looking into a number of potential suppliers they chose the Evowash sand washing plant from Northern Ireland company, CDE Global. The new sand washing plant includes the Evowash 71 and Evowash 151 (Fig.) supplied by Ankerløkken Equipment who represents CDE in Norway.
Samples taken of material from the site suggest it to be one of the best reserves of natural sand and gravel in the South of Norway. The current processing licence is initially for a 20 year period with an option to extend for several more years. Current production capacity at the site following the addition of the two Evowash sand washing plants is 200 000 t/y. Reddal Sand is a member of PGL – the Norwegian Federation of crushed rock and sand and gravel suppliers and all the concrete aggregates produced meet the relevant Norwegian quality standards in co-operation with the Control Council for Concrete Products.
