Hybrid power without compromise

SBM Mineral Processing offers a total of 12 JAWMAX^® track-mounted jaw crushers and REMAX impact crushers, with operating weights ranging from nearly 50,000 to 350,000 lbs (23.0 to 160.00 tonnes). The unique selling point of SBM's mobile machines in all classes is the sophisticated diesel-electric drive concept with the option of full all-electric plug-in power supply from the grid or other external power sources. The numerous hybrid solutions that have appeared on the market in recent years prove that the hybrid pioneers have been right for a good four decades. In reality, however, the competition is often limited to the light 30-tonne and under segment, or offers only partially electrified models, or large crushers with multiple transport units that are difficult to move.

Here, the highly mobile JAWMAX and REMAX models are completely different in their performance ranges from 200 to 600 tonnes per hour: The consistent integration of diesel/generator combinations and the extensive electrification of all drives like screens, conveyors as well as essential hydraulic components (crusher adjustment, crawler drive, lifting cylinders) result in compact transport dimensions and weights, ensuring easy one-piece low-bed transport and fast set-up times on site. In terms of feed size and screening equipment, all SBM mobiles are well ahead of their respective performance classes, which significantly increases productivity in raw materials and recycling.

"Economic efficiency, environmental sustainability and HSE are playing an increasingly important role in operations, especially in the UK market," says Norbert Dieplinger, referring to stricter emissions regulations and industry-wide efforts to improve the environmental footprint of conventional drives with alternative fuels such as HVO. "Our diesel-electric drives with the latest Stage V engines are inherently much more efficient than fully hydraulic or only partially electrified system concepts – on average we use up to 40% less diesel for an even better output. Thanks to variable fixed speeds of our engines and, of course, fully electric operation, the immediate environment also benefits from significantly lower noise levels."

Market premieres and perennial favourites

High productivity is also the focus of SBM's Hillhead exhibits: the company will be showing three machines – or the equivalent of 1500 t/h – on stand N16 and live in the adjacent live demo.

The presentation of the REMAX 600 impact crusher also heralds the UK market launch of SBM's new flagship. With an operating weight of only around 80 tonnes, the 1400 class impact crusher (inlet opening: 1380 x 1000 mm (W x H) produces a maximum of 600 tph, defining a completely new performance segment in mobile crushing. The plant offers real added value with its complete package of standard equipment plus options that provide a variety of high-quality final aggregate fractions. In addition to standard pre-screening via a double-deck circular vibratory screen, there are three optional secondary circular vibratory product screens (1, 2, 3-deck), all of which can facilitate the recirculation of oversized material, as well as highly cantilevered discharge conveyors for large product stockpiles. Even fully equipped, the plant can be transported in one piece and set up quickly (approx. 45 minutes) without the need for any auxiliary equipment, even for one-man operation.

The REMAX 600 is powered by a Cummins Stage-V diesel engine and a 520 kVA generator or, as an option, fully electric from the mains, with plug-in switching and all system functions managed by the intuitive SBM CRUSH CONTROL. The system actively supports the machine operator: even at maximum capacity and full integration of all production screens, uninterrupted one-man operation is guaranteed with optimised consumption data and low environmental emissions (dust, noise).

CRUSH CONTROL, the integration of new AI-based real-time analyses and satellite-based data exchange are also at the heart of the "Autonomous Crushing" project that SBM is driving forward on the basis of the REMAX 600 and about which the manufacturer will be providing comprehensive information at the trade fair.

Also on the stand, SBM will present the JAWMAX^® 450 jaw crusher as a universal, highly mobile 450 tph solution for raw materials and recycling. At the heart of the nearly 40-tonne plant is a jaw crusher with a high crushing force of up to 400 Brinell, a large feed opening of 1100 x 700 mm for piece sizes up to 800 mm, and crushing gap adjustment under load (40 – 160 mm). The CRUSH CONTROL system with automatic foreign object detection and overload protection ensures high availability. Crusher performance is further optimised by the 7 m³ feed hopper and an active double-deck circular vibrating pre-screen with triple flap chute controlling the discharge/bypass or blend of the screened fine fractions, reducing crusher wear and increasing production output thanks to a significantly more homogeneous crushed material. The SBM JAWMAX 450 is equipped with a diesel-electric hybrid drive (200 kVA) with plug-in power option and an electrically driven crusher (110 kW), to provide highest quality production at the lowest carbon footprint.

The track-mounted REMAX 450, which SBM will be demonstrating live, also features the innovative active pre-screening solution that optimises the performance of the class-leading impact crusher (1260 x 800 mm inlet) for feed sizes up to 1000 mm. The system achieves a maximum output of 450 tonnes per hour, with generously dimensioned transfers and conveyors allowing trouble-free production various defined end products in a single pass, even when fully equipped with fine grain side discharge and optional 1- or 2- deck secondary screen including oversize grain recirculation. With its 8 m³ feed hopper, large stockpile capacity and standard multi-function remote control, the large crusher can be efficiently operated by one person from an excavator or wheeled loader. Equipped with a 300 kVA diesel/generator unit and electric crusher motor (160 kW), the REMAX 450 weighs between 47 and around 54 tonnes, depending on the equipment – SBM quotes consumption values of between 25 and 32 l/h for diesel-electric operation as a reference.
