Keestrack B7e Jaw Crusher

Keestrack B7 Jaw Crusher
  • This field is for validation purposes and should be left unchanged.

The Keestrack B7 mobile jaw crusher is heavy-duty as it can come. Designed for processing the toughest rock in quarrying and mining applications, the B7e features a 2-step vibrating grizzly feeder, an 830 x 1,200 mm (32.6″ x 47″) feed opening, and a 6m³ hopper.

Optimal productivity and superior efficiency with a low cost per ton produced are achieved through technology innovations. The B7e is a fully hybrid unit driven by a 132-kW electric motor. An additional 55-kW electric motor is used to power the hydraulic system for the tracks, lifting cylinders, feeder, and conveyors. The entire diesel-electric power is delivered by the on-board Volvo diesel engine and 330 kVA generator. The engine house is available in a detachable drop-off module and can be positioned away from the crusher, in a dust and vibration-free environment.

Thanks to constant and low engine speeds, even under full diesel-electric load, the Keestrack B7e operates with low fuel consumption.
