Challenge accepted: An EVO plant train puts its strength to the test in Tanzania’s hard granite
A Kleemann plant train is flexing its powerful muscles in a Tanzania granite quarry. After an adventurous journey to the site, the MOBICAT MC 110 EVO2 jaw crusher, MOBICONE MCO 90 EVO2 cone crusher and MOBISCREEN MSC 953 EVO screening plant are performing in perfect unison.
A challenging journey: the Kleemann machines began their long voyage from Europe to Dar-es-Salaam, Tanzania. But that was only the beginning. After customs clearance, they continued their journey on flatbed trucks, by train and finally along a ten-kilometre-long unpaved road deep into the Tanzanian hinterland. The destination was a recently developed quarry some 40 kilometres from Mwanza town on the shore of lake Victoria, where Sasco Trading processes granite for infrastructure projects.
“The transport was quite complex and involved. It demonstrated just how important compact mobile plants are,” says Markus Hofmann, Kleemann Area Sales Manager Africa. “All the machines were relatively easy to load and transport thanks to their compact design – which proved to be a real advantage on this project.”
Working with granite: new opportunities for Sasco Trading
Sasco Trading is new to the business and harbours big aspirations. Tanzania is planning major investment in road construction over the coming years, and Sasco aims to become a strong partner in the material supply chain.
The rock to be quarried in the quarry is extremely hard granite. “We conducted an in-depth search to find out what equipment was available,” explains Sasco Trading owner Sabasi Shirima. Kleemann is the market leader in Tanzania, where several plant trains from the Göppingen-based company are currently in operation. “The crushing and screening plants have a very good reputation in Tanzania. This was ultimately the deciding factor for us. Now that we have seen the plants in operation, we know that we made the right decision.”
Efficiency, performance and quality
The MOBICAT MC 110 EVO2 jaw crusher carries out the primary crushing of the hard granite, which is up to 500 mm in size. The Kleemann cone crusher then refines the grain size and gets it into perfect shape. Finally, a downstream classification screen produces three high-quality end products: 0–6 mm, 6–10 mm and 10–18 mm. Other variants are also available depending on customer requirements.
The performance is impressive, to say the least. The plant trio processes up to 150 tons per hour – with amazingly low fuel consumption. The MC 110 EVO2 needs an average of only 12 litres of diesel per hour, while the MCO 90 EVO2 gets by with 19 litres. The screening plant is also extremely efficient, consuming only 16 litres per hour.
“The crushing and screening plants have a very good reputation in Tanzania. That was ultimately decisive for us. Now that we have the plants in operation, we know: Our decision was correct.” - Sabasi Shirima, owner of Sasco Trading
Intelligent line coupling keeps everything running smoothly
Intelligent line coupling ensures that the entire plant train runs smoothly. Each machine sends signals to the upstream and downstream machines in the event of overfilling or malfunctions. Thanks to the Continuous Feed System (CFS), the crushers are also ideally utilised. Each machine is optimally fed, which reduces wear and maximises performance. The intelligent line coupling further enhances safety: if an emergency stop is activated anywhere in the plant train, all machines are stopped safely.
“Intelligent interlinking is one of the plant train’s outstanding features. Thanks to automated processes, our customers can look forward to much higher output and much less maintenance,” points out Kleemann expert Jerry Muchiri, who supported the project in Tanzania.
Simple, intuitive operation
It was a real advantage that three of Sasco Trading’s plant operators already had experience working with Kleemann plants at another company. However, thanks to Kleemann’s intuitive SPECTIVE operating system, getting started with the new plant is quick and easy for all users. “Our employees found their way around very quickly,” reports Sabasi Shirima. “The training was thorough but very easy to understand – and the operation afterwards was extremely straightforward.”
Support from the word go: Kleemann on site
Another factor contributing to the smooth start was the ten-day on-site visit by a Kleemann service technician who provided commissioning and in-depth training. After a few weeks, once everyday work has settled down and all questions have been answered, a second round of training is available on site or via video conference, if required. “We know that we won’t be left on our own with any issues in the future. That’s peace of mind,” highlights entrepreneur Sabasi Shirima.
