Jaw crusher for primary crushing, landfill recycling, and demolition

Keestrack B3 Jaw Crusher

  • This field is for validation purposes and should be left unchanged.

As the global leader in the 30 tonne class, the Keestrack B3 jaw crusher (previously known as Argo) is a favourite in the crusher selection for its high productivity and fuel efficiency. Innovative designs make it known for being a reliable machine in a range of applications from primary crushing and landfill recycling, to construction and demolition.

While compact, this machine has excellent throughput and feed capabilities handling material up to 20” and producing at a capacity of 300 tph. The patented Non-Stop System helps protect the machine as it automatically detects when non-crushable material enters and intelligently opens the jaw to allow the obstruction to pass before resetting back to the initial C.S.S. User friendly controls, the ability to operate the jaw from an excavator and excellent access for maintenance and replacement of wear parts make this machine an operator’s dream.
