Kleemann │ An EVO Plant Train Processes Extremely Hard Granite in Tanzania

The Trio of Machines is Now at Work in a Newly Developed Quarry Close to Lake Victoria

After an extraordinary journey, three Kleemann plants – a MOBICAT MC 110 EVO2 jaw crusher, a MOBICONE MCO 90 EVO2 cone crusher, and a MOBISCREEN MSC 953 EVO classifying screen – are now hard at work as a line coupled plant train in an African granite quarry.

Easy Loading and Transportation

The Kleemann machines began their long journey on a ship from Europe to the port of Dar es Salaam in Tanzania. After clearing customs, the journey continued—on low-loaders, by train, and finally, deep into the Tanzanian hinterland on a ten-kilometer-long unpaved road. The destination was a newly developed quarry around 40 kilometers from Mwanza on the shore of Lake Victoria, in which granite is processed for the completion of infrastructure projects.

“Transporting the plants was a truly unusual and laborious task that showed just how important compact mobile plants are,” says Markus Hofmann, Kleemann Area Sales Manager Africa. “Thanks to their compact dimensions, all the machines were able to be loaded and transported relatively easily – that was a real advantage here.”

Efficient Three-Plant Train with Low Fuel Consumption

The MOBICAT MC 110 EVO2 jaw crusher takes care of the pre-crushing of the hard granite feed material with edge sizes of up to 500 mm. Following this, the Kleemann cone crusher produces finer grain sizes and brings them into shape. A downstream classifying screen then produces three final products: 0 – 6 mm, 6 – 10 mm, 10 – 18 mm – whereby other variants can also be produced according to customer-requirements.

The trio of plants processes up to 150 tons of rock per hour with remarkably low fuel consumption. On average, the MC 110 EVO2 needs only 12 liters of diesel per hour, and the MCO 90 EVO2 needs only 19. With a consumption of 16 liters per hour, the classifying is also extremely fuel-efficient.

Smart Line Coupling Warns in the Event of Overfilling

Smart line coupling guarantees that all machines of the plant train maintain a smooth and seamless crushing and screening process. In the event of overfilling or malfunctions, each machine signals this to its upstream and/or downstream neighbors. Crusher utilization is also optimized with the aid of the Continuous Feed System (CFS). The use of this machine feeding concept reduces wear and maximizes output. Smart line coupling also increases safety: all machines are stopped as a safety measure as soon as an emergency stop is initiated anywhere on the plant train. “Smart line coupling is one of the important features of the plant train. Thanks to the automated processes, our customers can count on considerably higher production and significantly less maintenance,” emphasizes Kleemann expert Jerry Muchiri, who accompanied the project in Tanzania.

Simple and Intuitive Operating – Thanks to SPECTIVE CONNECT and On-Site Training

Thanks to the intuitive SPECTIVE operating system, getting started with the new plant train was quick and easy for all users. “Our employees found their bearings very easily,” reports Sabasi Shirima, owner of Sasco Trading. “The training was intensive, but very easy to understand – and operating the plants afterwards was really straightforward.” A Kleemann service technician spent ten days at the quarry commissioning the plant train and providing intensive training for the operating crew. “We know that we will not be left alone with questions in the future, which is a very good feeling,” stresses Sabasi Shirima, who knows and appreciates Kleemann and the Wirtgen Group as reliable partners who always fulfill their worldwide service promise.
