Keestrack B7 Jaw Crusher

Compact, versatile and mobile classifier screener for sand and gravel, coal, and C&D applications

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 is 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.

Benefits

 


Steel hydraulic lines

Steel Hydraulic lines are used throughout the crusher. Offering many benefits including increased strength, improved safety, easier repairability and better heat distribution, these steel hydraulic lines improve the lifespan of the oils used in the crusher.

Fuel efficient

Thanks to constant and low engine speeds, even under full diesel-electric load, the Keestrack B7e operates with low fuel consumption. Energy-saving costs of up to 80% can be obtained in the emission-free plug-in operation from mains or external gen sets.

Automatic wear recovery

The automatic jaw wear recovery system checks the set CSS of the crusher every 50 hours and readjusts it to the correct CSS. This process can also be done manually ensuring consistent quality and sized crushed end product.

Non-stop system (NSS)

The NSS (Non-stop overload safety system) is a hydraulic and electronic safety protection system that guarantees continuous production and protects the machine from uncrushable feeds. If a large unbreakable piece enters the crushing chamber, the jaw opens automatically and resets itself to the original setting.
