NPC change the face of washing in South Africa

摘要

Natal Portland Cement have announced major productiv-ity and efEciency improvements at their Sterkspuit quarry in KwaZulu-Natal/South Africa following the introduc-tion of a new washing plant from CDE Global. The loss of quality fines during the sand processing phase of production has been eliminated following the introduction of the CDE EvoWash plant to replace a bucket wheel de-waterer previ-ously employed at the Sterkspuit site. NPC also report an industry first with the introduction of an AquaCycle high rate thickener allowing for the recycling of 90 % of the water used in the washing of their crushed material. While thickener Systems are in use throughout the mining sector in South Africa it is believed that the CDE AquaCycle now in Operation is the first of its kind in a crushed rock or sand and gravel application.
