Eren Construction is one of the largest multi-disciplinary construction companies in Turkey, and its project focused on processing limestone and basalt for use on a 63km section of a major 221km canal construction project designed to take water from the Attaturk reservoir to the east of Turkey.

On winning the project Eren Construction ventured into aggregate production for the first time in an effort to reduce costs and increase control over the supply chain. Previous to this the company would have used large quantities of river won aggregates but new legislation in Turkey required that it explore other avenues of supply. 

The initial investment involved the purchase of two mobile crushing and screening plants. As the project developed it became clear that the material being blasted and excavated on site to be reintroduced to the canal construction project required a washing process in order to be able to deliver the quality of sand and aggregates required for use in the civils. 

The dry crushing and screening process served its purpose adequately in the early stages of the project but as time went by the company soon realised that washing was needed due to the volume of silt and unwanted fines in the excavated material. And the nature of the project required that the washing plant be mobile as it would be moved every few months as the project progressed towards completion.



CDE recommended the M2500 mobile washing plant to Eren Construction. The M2500 offered the mobility that was needed whilst also ensuring that the sand and aggregates were of the highest possible quality due to the very efficient removal of silts from the feed material.

The M2500 worked alongside a Metso crushing and screening train, processing basalt that has been blasted and excavated to form the new canal. The washed sand and aggregates were used in the manufacture of concrete which was used to form the civils for the canal. This project alone proves the mobility of the M2500 as it was moved along the canal banks every two months as the project progressed.

The M2500 was fed at rate of 125 tonnes per hour from the dry crushing and screening plant. The feed conveyor delivered the material to a double deck ProGrade P275 rinsing screen fitted with wire mesh on both decks. +22m material was removed by the top deck and 15-22mm by the bottom deck and these products were stockpiled by the integrated 9m wing conveyors.

-15mm material was sent to the integrated EvoWashTM sand washing plant where a split screen allows for production of a 4-15mm aggregate and 0-4mm sand, once again discharged to stockpiles via the integrated conveyors. It is the hydrocyclone technology employed on the EvoWash that allows for the effective removal of silts from within the feed material while the high frequency dewatering of the sand ensures that it is discharged at 12% moisture, ensuring it can be used in the production of concrete very soon after production.

In addition to processing the newly excavated material the M2500 was also used to process some 60,000 tonnes of material that had been stockpiled on site awaiting the arrival of the new washing plant.

“Carrying out the washing and screening in house has been a big experience with a lot of learning in the process but other aggregates projects are inevitable now with the new legislation so it has been a positive step for the company. The M2500 has been a very good solution for us.”
Mr. Yasar Eren, Chairman of Eren Construction.


The M2500 produced four washed products – 0-4mm sand and 4-15mm, 15-22mm and +22mm aggregates and proved the right solution for Eren Construction. It enabled the company to effectively deal with the issue or excess fines in the dry screened material and provided a mobile solution that demonstrated the capability of the unit on large civil engineering projects for the production of sand and aggregates on site.
