An MB BF90.3 crusher bucket has been working day and night on a school project in Doha, Qatar, processing over 60,000 cubic metres of limestone for recycled use.

Mounted on a Volvo EC240B excavator, the Italian-made BF90.3 crushes the material from the foundations and the underground car park to different sizes for re-use to fill on-site excavations and as subgrade for the roads within the school. The material texture can be changed by adding or removing thicknesses from the MB crusher in just a few minutes.

The project is the second stage of the construction of Oryx International School, a British-style Orbital Education Group school for the children of Qatar Airways (QA) employees.

The first construction stage (Oryx Minor) was completed in November 2016, when the first buildings became operational. The second stage (Oryx Major) started in June 2017 and is planned to be completed in May 2018.

It involves the construction of 41,000 square metres of campus and a three-floor building with new classrooms, laboratories and gyms for over 2000 students.

The BF90.3 crusher bucket was purchased by Boom General Contractors (BGC), a large Qatari construction company.

"We chose the MB crusher bucket because we can crush the material directly on site, without having to bring a large crushing station," BGC project manager Pier Matter says.

"This saves us transport costs for other machinery, as the crusher bucket is carried together with the excavator. Once it is on site, it can be assembled very quickly, and we are ready to work in a few minutes.

"It is also easy to use," Matter says. "From the excavator cab, the operator picks up the material with the crusher bucket and crushes it on the spot.

"Time is a critical factor for us, which means that having a machine like the MB crusher bucket on site is really helpful, also considering the amount of material we need to process.

"The crusher bucket does not need special maintenance in addition to basic maintenance," he adds. "It also requires very low amounts of water, which makes it easy to work with the other excavators we have on site."

The BF90.3 was the first crusher bucket to have been placed on the market, and today has reached its fourth series, MB says. The more compact bucket can now yield up to 42 cubic metres per hour depending on the processed material, and can yield materials of 15mm to 140mm.
