EvoWash sand washing plant and AquaCycle thickener accepts blended dune sand, crushed limestone & gabbro for use in block making and ready mix concrete.
A new sand washing plant from CDE Global has recently been installed in the Kingdom of Saudi Arabia for the Abdullah Abdein factories for cement production. The plant is located in Tabuk in North West KSA and includes an Evowash 151 sand washing plant and an Aquacycle thickener.
The 150tph washing plant is processing a combination of dune sand and crushed limestone and gabbro in order to produce material for use in a new block making factory and ready-mix batching plant. This has resulted in significant production efficiencies for Abdullah Abdein Bukhary as they were previously buying in the sand required for these operations. “This is a common model throughout the world” explains Ruchin Garg, CDE sales manager for the Gulf region. “The efficiency gains that can be realised by producing your own material rather than having to buy material in are significant.”
A key factor in the success of this installation is the ability of the Evowash to accept a combination of feed materials. This was required in this instance in order to produce the sand specification required for use in the black making factory and ready-mix production. Given the variation between the composition of the dune sand and crushed rock feed it was recommended that the 2 materials be blended prior to processing through the Evowash. “By blending the materials the plant is able to deliver the required 150tph processing throughput” says Ruchin Garg. “This is because the dune sand is a very fine material so if processing this material on its own the capacity of the wash plant would be reduced to approximately 120tph. Blending the two materials allows the customer to maintain the required capacity while also delivering high quality concrete sand.”
The project for Abdullah Abdein was delivered in partnership with the Middle East Development Company (MEDCO) who has headquarters in Jeddah and a number of other offices throughout the Kingdom of Saudi Arabia in Riyadh, Al-Khobar and Abha. Commenting on the project, Mr. Tariq Abdullah Abdein the General Manager said “the Evowash operates efficiently and has had a positive effect on the quality of our concrete products. The plant has also reduced our water consumption ”.
Mr Sameh Awny El-Hofy of MEDCO added “The Evowash and Aquacycle in combination provides the template for how operators can introduce a washing plant to their processes in the Gulf region as it effectively tackles the issues around water availability that until now have been a major barrier.” According to Ruchin Garg the introduction of the Aquacycle thickener allows operators to enjoy the efficiency gains that the Evowash offers and also benefit from the flexibility of the Evowash system. “The Evowash has been chosen on hundreds of our global installations for the simple reason that it offers the most efficient sand washing system available.”
