In the coastal region of Stockholm, a construction contractor is taking another step into the future: the entire crushing and screening process is being handled by a purely electrically powered, line coupled plant train from Kleemann consisting of a MOBICAT MC 120 PRO jaw crusher, a MOBICONE MCO 110 PRO cone crusher, and a MOBISCREEN MSC 953 EVO screening plant.
The spectrum of applications it can handle is impressive. As the contractor predominantly processes granite and recycling materials, it is often necessary to adapt the machine settings to cope with the wide range of different feed materials. This is one of the reasons why a complete plant train consisting of three Kleemann machines is now in use. From the jaw crusher, the crushed material with a grain size of 0 – 150 mm is passed to the cone crusher, where, after further crushing to a size of 0 – 60 mm, it finally reaches the mobile classifying screen, which separates it into three fractions with the following grain sizes: 0 – 16 mm, 16 – 32 mm, and >32 mm.
Purely electric – out of conviction
There’s quite a difference to the way the company handled materials processing in the past. Today, the entire plant train is exclusively electrically powered. ‘Our decision to go fully electric was motivated by energy-saving considerations and the desire to reduce emissions’, explains co-owner Freddie Erickson, co-owner of Kentas Last & Schakt AB.
The investment also pays off in financial terms: The company estimates that the operating costs otherwise incurred by diesel fuel consumption are more or less cut by half when using an electric power supply. The procedures are also simpler and save valuable time: no daily refuelling, no warm-up times and, as the electrical systems are more reliable, maintenance tasks are also easier and less complex.
The conditions at the location also confirmed the viability of the Swedish company’s project from a financial and logistical point of view. A substantial six-figure Euro sum was invested in infrastructure measures, including a transformer station and the laying of underground power supply lines. There was no state funding.
Rugged technology for challenging materials
The individual components of the plant train are interlinked by smart line coupling, which, thanks to automated regulation, guarantees a stable process chain from end-to-end. The machines communicate via fill level sensors and autonomously regulate their output: The upstream machine, for example, reduces the feed when the downstream machine reports a high fill level. If an emergency stop is activated anywhere on the train, all machines are stopped simultaneously.
SPECTIVE CONNECT is used for operating on site. It allows machine data and settings to be conveniently viewed and adjusted on a smartphone – safely and efficiently, without having to be present in person directly at the plant.
Pushing the envelope of change
The experience gathered with all-electric operation has been positive across the board. In view of the results, the company in Sweden is already planning the electrification of further machines: ‘We are actively working on the conversion of as many of our machines as possible to electric power. This is clearly the way forward, and we are determined to implement this change across our entire fleet.’

New Kleemann Plant Marks Commitment to Industry
In early 2010 Kleemann GmbH completed its new headquarters and state-of-the-art manufacturing plant near Göppingen, just east of Stuttgart in south-central Germany.
The new plant marks Kleemann’s commitment to the minerals processing industry and incorporates the highest production technologies for the manufacture of aggregates and minerals processing equipment.
This new “greenfield” manufacturing plant is making Kleemann mineral processing equipment more available, and will speed product delivery in North America in coming months. “With 350,000 sq. ft. of production area and 40,000 sq ft of administration area, Kleemann will excite the market with new models and features for 2010,” said Evan Clarke, vice president.
For over 150 years Kleemann has led the minerals processing industry with design ingenuity, producing crushing and screening equipment for many leading markets. Since being acquired by the Wirtgen Group in 2006, the company has experienced dramatic growth which has led to reinvestment by the group to help streamline production and allow for greater volume for its new expanding markets.
“As Kleemann gathers momentum within the United States and Canadian markets, and new dealers take on the product line, many customers are seeing the ‘Kleemann Advantage’,” Clarke said. “We bring to the market a wide range of track mobile crushers and screens with many unique features.”
The new plant utilizes the most modern German high-tech manufacturing processes, including short internal product assembly lines. On the new 1.34 million sq. ft., site, the new manufacturing facility covers an area of 376,736 sq. ft., complemented with a 43,055 sq. ft. administration building. The oversized interior capacity of the new main production facility accommodates the enormous dimensions of Kleemann’s largest crushing and screening machines.
In the plant’s central warehouse contains two storage zones in which some 10,000 items are stocked. “On average, 200 items with a total weight of 8.8 tons are handled here each day,” said Kleemann central warehouse manager Martin Zemmel. “We really benefited from the know-how of the other Wirtgen Group companies when building our new facility.”
Kleemann’s new painting facility for large parts is one of the largest such facilities in Germany, with a tremendous load-bearing capacity of 33 short tons, and around 21,500 sq. ft. of floor space. Kleemann’s switch-over from wet spray painting to powder-coating not only marks a major step towards boosting surface quality, but also has far less of an environmental impact, with the system far exceeding the requirements of the EU environmental guidelines.
Kleemann’s Roots Run Deep
Kleemann is a newcomer to the North American aggregate processing market, but its roots lie deep. Established in Germany in 1857, Kleemann was acquired by Wirtgen Group in 2006. Today, a growing network of equipment distributors and dealers is enabling Kleemann Inc. USA to boost its domestic profile and serve customers in North America.
Today Kleemann manufactures and markets a broad range of durable, productive mobile and stationary processing equipment and technology for crushed stone, demolition waste and mixed construction waste.
Kleemann’s product brand names are:
• The MOBICAT mobile primary jaw on crawler chassis with feeding unit, pre-screen and conveyors built in various sizes ranging from 100-1,000 tph capacity
• The MOBIREX mobile primary impactor on crawler chassis with feeding unit, pre-screen and conveyors built in various sizes ranging from 100 to 1,000 tph capacity
• The MOBIFOX mobile secondary crushing machines with feeding unit, impact crusher and a screen producing up to 3 grain sizes
• The MOBICONE mobile secondary crushing machines with feeding unit, cone crusher and a screen to produce up to 3 grain sizes, and
• The MOBISCREEN mobile screening machines, producing up to 4 grain sizes with fixed or swiveling discharge belts, with a screening surface dependent on ultimate use.
