The Keestrack B7 mobile jaw crusher is built for the toughest rock in quarrying and mining applications. This powerhouse features a 2-step vibrating grizzly feeder, a massive 32.6″ x 47″ (830 x 1,200 mm) feed opening, and a spacious 7.85 cubic yard (6 m³) hopper.

What sets the B7e apart is its cutting-edge technology that ensures top-notch productivity and efficiency at a low cost per ton. This fully hybrid unit is driven by a robust 177-horsepower (132-kW) electric motor, with an additional 74-horsepower (55-kW) electric motor powering the hydraulic system for the tracks, lifting cylinders, feeder, and conveyors. The entire diesel-electric power system is supplied by an onboard Volvo diesel engine and a 330 kVA generator. For added convenience, the engine house is available in a detachable drop-off module, which can be positioned away from the crusher in a dust and vibration-free environment.

Thanks to its constant and low engine speeds, even under full diesel-electric load, the Keestrack B7e operates with impressively low fuel consumption. This crusher is not just a machine; it’s a game-changer for your toughest jobs, delivering unparalleled performance and efficiency.
