Digging in deep
The Wirtgen Group's Mineral Technologies division offers a well-matched range of products for mining and processing minerals with the Wirtgen Surface Miners and Kleemann crushing and screening machines.
Extracting minerals in open cast deposits and processing mineral raw materials is an extremely demanding task for which a durable, high performance equipment is an absolute necessity. Owing to many years of experience in the field of mineral technology, the Wirtgen Group has adapted its innovative and practical technology to the most extreme conditions of use. Its robust machines offer great reliability and cost-effectiveness for everything from material extraction to material processing.
Wirtgen surface miners
The established mechanical mining procedure is accomplished without conventional drilling, blasting and pre-crushing. Wirtgen uses its high-performance cutting technology to enable the surface miners to function much like cold milling machines. It cuts and crushes the rock with a special cutting roller and the sturdy conveyor systems load it onto dumpers or deposit it beside the Surface Miner. Alternatively, the rock can also be placed between the chassis behind the machine. The Wirtgen Surface Miners have cutting widths of 2.20 m to 4.20 m and cutting depths of 20 cm to 83 cm up to a uniaxial compressive strength of 120 MPa. Special machines for rock construction can even cut hard granite up to 260 MPa. Moreover, Wirtgen is the only manufacturer that covers a performance spectrum from 100 t/h to 3000 t/h.
Robust product range
With the 2200 SM, 2500 SM and 4200 SM, Wirtgen offers three proven and tested performance classes which can be variably configured specifically for each project. All the machines can be configured to either load the material into dump trucks or deposit it as a windrow behind the machine.
The surface miners' fields of application include opencast mining and routing work on roads, railway lines and tunnels. This enables the selective extraction of valuable minerals, coal, limestone, gypsum, bauxite, phosphate and iron ore with great purity. Constant expansion of the spectrum of use means that surface miners are also used for special applications in salt mining, granite, kimberlite and oil shale.
Kleemann's crushing and screening
The Wirtgen Group also offers a wide range of jaw, impact and cone crushers and as well as screening machines for processing mineral raw materials. Kleemann has been in the business of processing natural stones for more than 150 years. Pieces of rock obtained from drilling and blasting work in quarries are processed to defined grain sizes. These classified final granulations are used as standardised additives for concrete and asphalt base, binder and surface courses in road construction as well as civil engineering.
In addition, Kleemann provides customers' with built-to-suit products that are designed to handle the hardest minerals and materials in the mining industry.
Jaw crushing performance
Jaw crushers serve as classic primary crushers for natural stones. The mobile machines' performance spectrum ranges from 100 to 1500 t/h. The extremely robust, high-performance machines, with feed capacities ranging from 450 t/h to 1000 t/h, are used for traditional quarry applications.
Secondary crusher units such as track-driven impact and cone crushers are electrically interlocked to work in tandem with primary crushers and screens. The screen area of the chain-driven screening machines ranges from 7 to 18.4 sq m. Their performance spectrum runs all the way up to 1000 t/h, making them well-suited for materials which are difficult to screen. Stationary machines with capacities from 100 to 1000 t/h handle all the other individual processes in addition to crushing and screening, such as washing, sand processing, mixing, dust collecting, etc, thus rounding off the range of offers.
All in one package
With a broad product range and decades of practical experience in application technology, Wirtgen offers customers tailor-made solutions from a single source - worldwide.
