Do slabs fall through your jaw crusher without being crushed? Do they fail to break, creating blockage? Columbia Steel has the solution.

slab breaker jaws for recycling asphalt and concrete

We’ve been helping jaw crusher operators recycle concrete and asphalt materials for over 35 years. Columbia Steel offers slab breaker jaw designs for most popular crushers, making your jaw crusher a more cost-effective recycling tool. We have slab breaker jaws for nearly 70 different crusher makes and models — ask us about the right one for you.

Slab breaker jaws are based on our traditional and high tooth jaw designs with additional raised slab breakers located in pitch with the conventionally located teeth. The number of slab breakers is in proportion to the width of the size and model of the jaw crusher. This allows you to set your discharge setting for a reasonable opening and still break slabs that otherwise would flow through the crusher.
