A new sand washing plant for Reddal Sand is said to have resulted in a significant improvement in the quality of the sand being produced at its site in southern Norway Reddal Sand
, located in Grimstad, Aust-Agder, has supplied a variety of construction materials to major projects in the area since 1989, including materials for use in the manufacture of roofing tiles, concrete, road construction and various types of ground works (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 3-4m 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 it chose the Evowash sand washing plant from Northern Ireland company, CDE Global
“We chose CDE equipment as a result of the experience they were able to demonstrate in the provision of equipment for similar applications in many countries,” says Morten Pedersen. “An additional factor in their favour was the flexibility they showed in terms of being able to customise the plant to the specific nature of the material we are processing.”
The new sand washing plant includes the Evowash 71 and Evowash 151 supplied by Ankerløkken Equipment who represents CDE in Norway.
“The Evowash allows us to maximise the production of quality sand. The new installation has ensured that we are able to offer a higher quality sand product to our customers, which sets us apart from other suppliers in the area,” says Morten Pedersen.
Reddal Sand is supplying material to a diverse range of customers including roof tile manufacturer Skarpnes as well as Skarpnes Rør (concrete pipes), and Ribe Betong, Digernes Betong and Betong Sør (all concrete). The company also supplied all the aggregates used on the construction of the new E18 road between Grimstad and Kristiansand through Ølen Betong (concrete).
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 200,000tonnes per year.
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 cooperation with the Control Council for Concrete Products.
