A New Cutting Drum Expands the Range of Applications for Surface Miners in Hard Rock and Stone

Wirtgen Surface Miners and Cross Application Miners are deployed around the world in open-cast mining operations and on infrastructure projects. Cutting drums are the core element of the machines. At MINExpo 2024, from September 24 to 26, 2024 in the Las Vegas Convention Center, the highlights from the Wirtgen Group will include insights into its cutting technology solutions. The focal point on Booth 6815 at the show will be a new cutting drum that now also enables the cost-efficient extraction of resources with uniaxial compressive strengths of over 100 MPa UCS (14,500 psi).

Limestone, Gypsum, Anhydrite, and Other Hard Rocks and Minerals

The new cutting drum is equipped with HT14 toolholders and features a redesigned cutting geometry. The field-proven and established central-drum concept, which ensures optimum utilization of the machine weight, and the direct belt drive that guarantees the transfer of high usable power to the cutting drum, also contribute to the ability of Surface Miners to profitably extract even very hard rocks and minerals with uniaxial compressive strengths of 100 MPa UCS (14,500 psi) and more – for instance limestone, gypsum, or anhydrite.

The Wirtgen 280 SM(i) with the New Cutting Drum in Action

The new cutting drum celebrated its premiere in practice on a limestone quarrying job carried out by a Surface Miner 280 SM(i) in Louisville, Nebraska. In addition to the extraction of very hard limestone at the quarry, the elimination of the need for drilling and blasting made it possible to extract previously unexploitable limestone deposits and extend the working life of the quarry and all downstream production systems by several decades. For the quarry operator, surface mining is a cost-effective extraction solution that also contributes to safeguarding jobs, increases safety in the quarry, and enables responsible management of resources.

Faster Infrastructure Projects 

Wirtgen expanded its portfolio of products and applications with the Cross-Application Miner 260 SX(i) two years ago. The Cross Application Miner speeds up construction times by eliminating the need for drilling and blasting, with the construction of stable embankments, in-situ grading of railroad tracks, and the recycling of the extracted material in-place for use in further construction.

Wirtgen Group Services: Expertise and Best Practices Are Essential 

At MINExpo 2024, trade and industry visitors to the show will also be able to talk with surface mining experts from the Wirtgen Group about all other aspects of the solution – for example deployment and project

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.
