In 1950, Franz Wageneder, the owner of a gravel pit in Upper Austria, laid the foundation stone for the contemporary company SBM Mineral Processing GmbH with his revolutionary swivel-beam-mill. “We proudly bear the initials of the revolutionary impact mill technology in our name, and of course we will be celebrating ‘75 years SBM’ in style at bauma,” explains Erwin Schneller, Managing Director of the company, which currently has some 180 employees at its headquarters in Oberweis near Gmunden/Austria. “In fact, we have paved the way for many new technologies, which in turn have had a significant influence on the developments in both the aggregates sector and the building materials industry. Already at an early stage we had developed mobile crushers and were also among the pioneers of track-mounted crushing plants as the basis for the modern recycling of building materials. The same applies to concrete mixing technology, where we continue to set standards in on-site production of high-quality concretes for construction projects with challenging requirements for various output capacities and the most demanding environmental conditions.”
Numerous exhibits on a total of around 650 m² of hall and outdoor space will build the bridges to the present and the future in Munich: “The pioneering nature of our developments becomes particularly evident in mobile processing, where more diesel-electric crushing plants will celebrate their bauma premieres this year than ever before. SBM has been systematically focussing on efficient and environmentally friendly electric hybrid drives for over 40 years and now offers perfectly sophisticated systems in all power classes with its REMAX impact crushers and JAWMAX® jaw crushers. In turn, we utilise the control technology advantages for the intelligent automation of the production process – in around two years’ time, we will further extend our lead in this area with the first ‘autonomous crusher’.”
The SBM portfolio continues to include the construction and modernisation of stationary gravel and ballast plants, concrete mixing plants and construction material recycling centres. “In this difficult market, which is currently characterised by a small number of major projects, we are relying above all on our lean and highly flexible structures as a medium-sized plant manufacturer.” These include the “SBM Technical Centre”, an in-house rock laboratory for the precise design and reliable validation of the required equipment, short communication channels between development and construction, as well as a wide range of high-performance individual machines for mineral processing, and modular stationary solutions for concrete technology. “Particularly for modernisations, but also for small to medium-sized new plants we score points with innovative and customised concepts that offer operators maximum cost efficiency and predictable security of the business location,” says Erwin Schneller, outlining the ambitious objectives of SBM plant engineering, whose activities in the major Central European markets are managed centrally from the headquarters in Oberweis.
Mobile mineral processing: Always in a class of its own
Even at its pre-series launch at the last BAUMA trade fair, nobody could get past it – the track-mounted large impact crusher REMAX 600, which is once again dominating the SBM mineral processing exhibition stand this year. Officially on the market for a good two years, the 600 t/h plant has been successfully placed in important regions and across all major industries according to SBM. In addition to the high performance of the class-leading 1400 impact crusher for natural stones and recycling (feed size: 1000 mm), the economical sustainability in operation is particularly impressive: the fully hybrid plant with EU 5 engine and 520 kVa on-board generator consumes 30 to 50 % less diesel in direct comparison to conventional diesel-hydraulic or only partially electrified large-scale plants. REMAX 600 finally becomes an environmentally friendly cost saver with the plug-in option for connection to external power generators or grids, which SBM will be demonstrating in Munich with a new plug system including a second mains switch that is easy and safe to operate.
And it does so with a mobility and flexibility that is unrivalled among large track-mounted plants: despite being fully equipped with an active double-deck primary screen, efficient longitudinal and cross discharge by magnetic separator, and up to three screening stages in the secondary screening unit with oversize grain recirculation, the plant REMAX 600 weighs less than 90 tons; as a “one-piece” unit, it can easily be moved from one location to another and is ready for use there within a very short period of time without needing any additional auxiliary equipment. The intelligent SBM “Crush Control” system supports the machine operator right from the set-up stage – it then monitors the entire production process and uses a comprehensive sensor system to ensure trouble-free and smooth material flows of the plant.
This means that REMAX 600 is still the pre-stage of the “autonomous crusher”, whose development is on the home straight according to SBM and its research partners at the University of Leoben: Following the successful integration of special sensors to evaluate the final products, the company is currently working on optimising the also AI-supported visual real-time detection of the feed material. At the same time, SBM is also continuing to expand its global information networks, which will later connect each ‘autonomous’ crusher to the SBM headquarters via cloud-based data connections. There, a “digital twin” of the plant will then in real time validate the settings made on site or optimise the crushing processes based on constantly growing reference data. The new technology is expected to be ready for the market by 2026 and will also be used in future generations of smaller mobile plants – in addition to the SBM flagship.
But even without AI, REMAX 600 still offers great potential: SBM will prove this in Munich with an especially developed add-on single-deck screen in a 6-m version. In a closed cycle, it provides a particularly high yield of defined fine grain sizes. Examples include asphalt recycling with end products of 0/8 or 0/10 mm or corresponding aggregates in natural stones or concrete recycling. Two magnetic separators ensure purity and quality: a highly efficient electromagnetic separator with cross discharge above the main discharge conveyor and a permanent magnetic separator with longitudinal discharge at the screen transfer point.
Focus on the client
By presenting the JAWMAX® 300 with its double-deck secondary screening unit, SBM will once again demonstrate its closeness to the market in Munich: Due to system-related lower wear costs and lower consumption figures, pressure crushing remains the technology of choice for many clients – albeit at the expense of reduced mobility at the construction site due to the additional screening equipment required. With a weight of less than 40 tons in “one-piece transport” and the production of three final products in one pass, the powerful 300 t/h jaw crusher (inlet opening: 1000 x 600 mm) now offers a flexible solution, e.g. for inner-city recycling or for the local processing of smaller raw material stockpiles or stored residual materials. If JAWMAX® 300 is used as a primary crusher only, the fully electric double-deck secondary screen (screen area: 1200 x 3000 mm) can be easily dismounted. Thanks to its modular design, it can also be used for the track-mounted impact crusher type REMAX 300 made by SBM.
With the reversible impact crusher SMR 13/7/4 and the vertical shaft impact crusher (VSI) V8, SBM will be presenting two individual machines in Munich that allow stationary plant operators to achieve higher added value through the production of high-quality chippings or sand from oversize aggregates in the course of new constructions or upgrades. The five SMR series (feed sizes: 150 mm/200 mm) can be used as secondary or tertiary crushers and impress in operation with a high proportion of cubic final products for the concrete and asphalt industry. The V8 vertical shaft impact crusher (VSI) is suited for the highly efficient production of sands and fine chippings. A patented inlet control ensures low-dust production in the full-load range with very high circumferential speeds of the rotor, whose design also guarantees a long service life.
