A high-performance duo comprising an impact crusher and screening plant from Kleemann, a Wirtgen Group manufacturing company, has recently helped complete infrastructure work at the Istanbul Financial Center (IFC) in the Turkish city.

The Mobirex MR 130i EVO2 impact crusher and the Mobiscreen MSS 802i EVO mobile coarse screening plant were utilised by Safir Proje, a multifaceted construction company, for the excavation work in the centre of Istanbul. Material was produced for concrete production and road substructures in the middle of the prosperous financial district. 

According to Managing Director Feyzullah Kahraman, Safir Proje was working on the project for about 18 months during which some one million tonnes of excavated material from the construction site was processed.

As the project location was challenging both in terms of the environment and the material, Kahraman decided to purchase two new flexible and mobile Kleemann plants for this application. The excavated material was processed very efficiently – directly on site – and some of it was combined with other materials for use on the project. 

Depending on the weather, the 0-500/600 mm feed material was at times wet and muddy, at others it was dusty and dry. Kleemann equipment provided the solution for these changing conditions. In wet weather, the Mobirex MR 130i EVO2 impact crusher was preceded by the Mobiscreen MSS 802i EVO coarse screening plant. It loosened the sludgy material, screened it coarsely and prepared it for feeding to the impact crusher. The first step was not required in dry conditions and the excavated material could then go directly to the impact crusher.

A variety of grain sizes were produced on site.

“We have seen that this combination produces the very best results – both in terms of product quality and cost-effectiveness,” says Kahraman. “We produced grain sizes of 0/38 and 0/63 and, depending on the end product, and could achieve an hourly output of 200 to 300 tonnes with a consumption of 24 litres. That’s impressive,” he reports.

The managing director was not only extremely satisfied with the quantity, but also with the quality of the result: “The impact crusher meets the requirements for the cubic material very well. I’ve never achieved this quality before.”

The fact that only one machine needed to be refuelled in dry conditions when the impact crusher was running without pre-screening was very cost-effective. It resulted in a noticeable reduction in operating costs. And the coarse screening plant could then easily be used for other projects.

With its proportionally controlled travelling gear, the equipment can be moved quickly and easily. Set-up times are short, partly because the side discharge conveyors are folded instead of dismantled.

The Mobirex MR 130i EVO2 excels with outstanding performance and top product quality.

Kahraman was in close contact with Kleemann in order to achieve this perfect set-up.

Operations at the Istanbul site have now concluded smoothly. “It’s also great that all our employees enjoy working with the plant,” says Kahraman. The favourable ergonomics and easy access to all relevant parts for service and maintenance make work much easier. “Thanks to Spective, handling the impact crusher is very straightforward and clear. Operation is so intuitive that hardly any familiarisation time was required. Of course, my employees are also quite proud to be able to work with a Kleemann,” adds the managing director.
