A powerful Kleemann plant train is making its mark at a granite quarry in Tanzania, showcasing strength, efficiency, and reliability
The set-up includes the MOBICAT MC 110 EVO2 jaw crusher, the MOBICONE MCO 90 EVO2 cone crusher, and the MOBISCREEN MSC 953 EVO screening plant, all working seamlessly together after an adventurous journey to reach the site.
A challenging journey to Mwanza
The Kleemann machines began their long trip from Europe to Dar es Salaam, Tanzania. After clearing customs, they were transported by flatbed trucks, rail, and finally along a rugged ten-kilometre dirt road deep into the hinterland. Their final destination was a newly established quarry near Mwanza, close to Lake Victoria, where Sasco Trading is processing granite for infrastructure projects.
“The transport was quite complex and involved. It demonstrated just how important compact mobile plants are,” commented 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.”
Sasco trading’s ambitious entry into quarrying
Sasco Trading, a newcomer to the industry, has set its sights high as Tanzania pushes forward with major road construction projects. The company sees a strong role for itself in supplying essential materials.
The granite being processed is extremely hard, making equipment choice crucial. “We conducted an in-depth search to find out what equipment was available,” explains Sasco Trading owner Sabasi Shirima. With Kleemann already established as a leader in Tanzania and multiple plant trains in operation, the company opted for their proven reliability. “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.”
High output and low fuel use
The plant train processes granite up to 500 mm in size. The MOBICAT MC 110 EVO2 handles the primary crushing, while the MCO 90 EVO2 cone crusher ensures the right grain size and shape. The screening plant then classifies material into three end products: 0–6 mm, 6–10 mm, and 10–18 mm, with other variants available on demand.
With a capacity of 150 tons per hour, the system delivers exceptional performance alongside low fuel consumption: just 12 litres per hour for the MC 110 EVO2, 19 litres for the MCO 90 EVO2, and 16 litres for the screening plant.
Sabasi Shirima emphasises the decision was right: “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.”
Intelligent line coupling and automation
The Kleemann plant train benefits from intelligent line coupling and the Continuous Feed System (CFS), which ensure efficient material flow and maximise crusher utilisation. Machines communicate automatically to prevent overloading, and in case of an emergency stop, the entire system halts 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,” notes Kleemann expert Jerry Muchiri, who supported the project on site.
User-friendly operation with SPECTIVE
Training new operators was straightforward thanks to Kleemann’s SPECTIVE operating system. Some of Sasco’s team had prior experience with Kleemann equipment, but even newcomers found the system easy to navigate.
“Our employees found their way around very quickly,” says Sabasi Shirima. “The training was thorough but very easy to understand – and the operation afterwards was extremely straightforward.”
Strong on-site support
A ten-day visit from a Kleemann service technician ensured smooth commissioning and detailed operator training. Additional training sessions are available later, either on site or via video conference.
“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.
