A testimony to the growing awareness in the quarrying industry of the multiple benefits of sand washing, the partnership between CDE Global and Estim Construction in Dar es Salaam, Tanzania was a labour of love and an exciting breakthrough in the African market.
The plant is fed 50 tons per hour to produce 40 tons per hour of final quality washed sand. Waste and water from the EvoWash report to the AquaCycle high-rate thickener so that up 90% of the water is recycled and reused. The concentrated fines are flushed out, resulting in minimal water replenishing the water tanks.
Director of Estim Construction says: “We could not be happier with the choice we made. Working with CDE Global, and especially their Business Manager and engineers, has been a crucial factor in achieving the best final product. “Thanks to our CDE Combo X70 we can now complete orders for various grades of concrete required for rafts, columns and slabs to produce paving blocks and other items in the knowledge that we will always meet our clients’ deadlines and produce consistent quality and output throughout the washing process.”
