An all-electric Kleemann plant train in Sweden
In the coastal region of Stockholm, the company Kentas Last & Schakt AB is taking a remarkable step into the future: The complete crushing and screening process is carried out there all-electrically – with a linked plant train from Kleemann, consisting of the jaw crusher MOBICAT MC 120 PRO, the cone crusher MOBICONE MCO 110 PRO and the screening plant MOBISCREEN MSC 953 EVO. The company thus becomes one of the pioneers in this sector in Scandinavia.
The range of applications is challenging: Kentas Last & Schakt AB predominantly processes granite and RAP material. The feed material therefore varies greatly, which means that the machine settings have to be frequently adjusted. The company decided on a plant train consisting of three Kleemann machines: From the jaw crusher, the crushed material with a grain size of 0–150 mm reaches the cone crusher, then, with a size of 0–60 mm, it reaches the mobile classifying screen where it is separated into three grain sizes: 0–16 mm, 16–32 mm and >32 mm.
All-electric – out of conviction
However, there is one difference compared to (previous) traditional plant trains: The complete train operates only on electricity. “Our decision to go fully electric was motivated by energy-saving considerations and the desire to reduce emissions," explains co-owner Freddie Erickson.
“The operating costs for an electric power supply are about half those for diesel.”
Freddie Erickson, co-owner of Kentas Last & Schakt AB, is convinced that switching to all-electric operation was a wise decision –and the reduced exhaust emissions on the site prove him right – both for the environment and for the overall efficiency of his company.
The investment also pays off in terms of efficiency: “The operating costs for an electric power supply are about half those for diesel,” says the entrepreneur happily. The processes have also been simplified: No daily refueling, no warm-up time, and even maintenance has become easier; the electrical systems have proven to be more reliable.
Of course, the changeover did not come without financial and logistical costs:Kentas Last & Schakt AB invested a high 6-figure euro sum in infrastructure measures, including a transformer station and underground cables. There was no state funding. But the location conditions were so good that the project could be mastered.
Initially, investment in the transformer station and the cables was necessary. But when the infrastructure was in place, the advantages outweighed the disadvantages.
