Keestrack B6 Jaw Crusher
  • This field is for validation purposes and should be left unchanged.

Equipped with a fully automatic feed system, hydraulic adjustment, and user-friendly controls with great maintenance access and replacement of wear parts, the B6 Jaw crusher (previously known as the B5) is ideal for primary crushing of medium and hard applications. 

The B6 Jaw Crusher is designed with a large independent 2-deck vibrating pre-screen, reducing wear and tear on the crushing chamber by removing fines from the material before entering the crusher and ultimately extending the lifespan of the machine. Low emission engine coupled with load-sensing hydraulics reduces fuel consumption by up to 25%, helping minimize the environmental impact of the operation.

Like all jaw crushers of Keestrack, the advanced patented Non-Stop System protects the crusher from uncrushable material by automatically opening of the jaw to allow the obstruction to pass and resetting the C.S.S. back to its original position ensuring a smooth uninterrupted crush.
