JPC ReadyMix Concrete has installed a new CDE air classification plant at its facility in Makkah, Saudi Arabia to improve sand quality and efficiencies in concrete production.
The new system from CDE Global is producing sand for use in the production of readymix concrete at an adjacent concrete batching plant.
The main success of the new plant lies in the effective removal of unwanted fines present in the feed material. Ian Walker, CDE sales manager for Saudi Arabia, explains: "An additional processing phase was required in order to ensure the production of consistently clean concrete sand.
The Sirocco air classification system has been proven to effectively achieve this. An given the water supply issues faced by JPC ReadyMix, the was the ideal solution." This is the latest installation for CDE in the Gulf region where an air classification system was the only option for the customer.
"For operators facing the problem of high fines content in the feed material, the Sirocco offers a viable alternative to washing. Simple dry crushing or screening will not effectively tackle this problem, which is why the Sirocco has enjoyed considerable success in recent years," says Iain Walker.
Commenting on the project, Mohammed Alamin, batch plant manager with JPC ReadyMix, says: "The sirocco presents and opportunity to increase the quality of sand we produce where we thought washing was the only option - an option that was closed to us due to lack of water at our site. The results from the Sirocco are very good: it is like washing without the water."
The 200-tonne-per-hour (tph) sand production plant includes the Sirocco W200 as well as a combination of feed and stockpile conveyors. There is also a dust suppression unit for the treatment of unwanted fines. All equipment was supplied by CDE Global and installation of the system was done by JPC ReadyMix Concrete.
