Keestrack B3 Jaw Crusher

Highly productive jaw crusher with capacities up to 300 tph processing feed up to 20″ in size

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.

Large jaw opening

The B3 jaw crusher features the largest jaw opening in the 30 tonne range of crushers. Measuring at 650 x 1,000 mm (24″ x 24″), the B3 can accept feed sizes up to 500 mm (20″) in size and with the C.S.S. ranging from 45 – 170 mm (1 3/4″ – 7″) users can produce a variety of quality end crushed aggregate products.

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 fluids.

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 a 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 open automatically and reset itself to the original setting.
