STE 108.75 TV – Track-mounted Mobile Jaw Crusher with Hydraulic Gap Adjustment
The track-mounted mobile jaw crusher with overload protection especially designed to process sleepers and demolished concrete can show off with the latest innovation in SBM´s jaw crusher segment. SBM experts succeeded in developing a new solution with hydraulic gap adjustment significant improvement in comparison to meaning conventional systems for these fields of application.

The Task
How is it feasible to feed up to 3 m long railway sleepers in one piece including ironwork and to process them in such a way that ironwork and concrete can be clearly separated while at the same time ensuring safe operation?
The conventional method still practised by competitors is using a hydraulic overload protection. This system requires extensive maintenance and is very susceptible to malfunctions as the forces of the crushing jaw are directly transferred to the hydraulic cylinders. 

The Innovation
The centrepiece of the new plant is the jaw crusher STE 108.75 ASV with a feed opening of 1080 x 750 mm and gap widths of 50 up to 200 mm.
The electric 132 kW-drive allows for an impressive production capacity of up to approximately 300 t/h when crushing concrete or up to 200 sleepers/h when crushing railway sleepers.
This new development aimed at determining the forces acting directly at the crushing jaw. If the measured crushing force exceeds the preset value the crushing gap is opened automatically. The "unbreakable" part can safely leave the crusher. Afterwards the moveable crushing jaw moves to the predefined initial position. The crushing process can be continued without any further delay.

Advantages for Clients

• Protecting the crusher against overloading due to "unbreakable" parts
• Fully automatic gap adjustment 
• Adjusting the gap width possible during crushing operation
• Start-up of the crusher possible with filled crusher mouth
• Current crushing gap is displayed at the touch screen of the plant
• Reduced maintenance and setting work resulting in higher availability of the plant

Setting an Example in Ecological Terms 

SBM´s guidelines to protect the environment were also implemented in this plant. Thus, STE 108.75 TV is a shining example with low emission values due to its diesel-electric drive and a super-soundproof power-engine. Additionally, the option to switch from generator to mains operation means low energy costs and at the same time low noise and pollution levels.

Obviously in Excellent Shape –
Impact Crushers SMR 10/10/4 and SMR 10/5/4(Trade Fair Exhibition)

For secondary and tertiary crushing of natural stones for the concrete or asphalt industry, this plant can successfully produce the cubic grain form required for further processing at a percentage of more than 90% valuable material in the end product.

Perfect for High-quality Asphalt Coverings
High-grade chippings for asphalt coverings have as yet been produced by a cone crusher and an additional impact crusher which has always meant an unsatisfactory product in terms of cubicity. This task is now undertaken by two SBM impact crushers which are each a power package convincing due to result and performance.

The impact crusher SMR 10/10/4 processes diabas with a feed size of 8/60 mm at a throughput capacity of 200 t/h and produces cubic high-grade chippings up to 22 mm. The material grain sizes 5/8 mm and 8/11 mm which are important for asphalt production are then screened to achieve a perfect final product with 90% cubic grain. A frequency converter provides constant circumferential speeds of the rotor which can be re-adjusted quickly and easily. In a parallel process, the impact crusher SMR 10/5/4 is used for feed material sizes of 32/60 mm and processes 80 tons diabas per hour in 7 impact stages. Using both SBM crushers permits the production of exceptional high-grade chippings even for open-pored asphalt coverings.

Advantages of SMR Impact Crushers

• Up to 90% cubic grain form 
• Uniform grain size distribution
• Simple maintenance due to open design
• Low filler content
• Long working life due to high-quality manufacture
• Low operating costs

Gigantic, Dynamic, Economic – The New SBM RECLAIMER
With the new development of a highly efficient reclaimer – a bridge bucket wheel reclaimer – SBM Mineral Processing GmbH broadens its product portfolio particularly for processed bulk materials. This SBM novelty is used where economic handling and homogenisation or temporary storage of large quantities of bulk materials are essential – an innovation especially for the raw materials industry. 
This reclaimer excels with a total width of approximately 65 m, an especially high loading capacity and maximum availability. Features like smooth operation even under extreme conditions such as e.g. snow, ice or heat  in a temperature range of -30 C° up to 40 C° and a reclaiming capacity of 1,100 t/h make this reclaimer a convincing plant due to its basic characteristics alone.

Multitasking
The reclaimer has an excellent storage capacity of 84,000 m³ per stockpile and can simultaneously work on two stockpiles in a dynamic process. The first stockpile is piled up layer by layer with processed material (grain size 0-8 mm) by a reversible distributing conveyor. The second stockpile is worked on by the reclaimer with a bucket wheel with 9 m diameter which removes the raw material semi-automatically respectively fully-automatically and transfers it to the loading of wagons by conveyors. 

PRODUCT-NEWS CONCRETE TECHNOLOGY

High-tech on a Greenfield Site – Supermobile EUROMIX^® 3300
The super mobile flagship of SBM Concrete Technology model range EUROMIX can present many of its strengths in the wind park in Flensburg. When concrete foundations are produced for wind power stations, highest demands are made on concrete quality and thus also on quality assurance. In addition to producing high-quality ready-mixed concrete these high-end plants are designed for especially extreme weather conditions as well as for flexibility respectively self-sufficient functionality.

EUROMIX^® 3300 is constructed to produce 145 m³ concrete/h and optimally adapts to its respective local conditions.

Requirements in the Wind Park Flensburg

• Installation of the mixing plant in the free field
• No foundations
• Extremely mobile operation
• Mobile infrastructure for electricity and water
• Just-in-time supply with rocks and cement
• Minimum transport efforts on public roads
• After completion of operation complete renaturation of the working area to grassland
