New & Used McCloskey J50's for Sale

The McCloskey J50 Jaw Crusher is a heavy-duty, high-production jaw built for operators who need reliable primary crushing across rock, quarry, gravel, recycled concrete, and C&D applications. Designed for production-focused crews who don’t want a “too small” jaw limiting throughput, the J50 delivers the combination that matters most in the field: strong jaw performance, efficient material flow, and jobsite-friendly mobility.

At US Equipment, we help you match the J50 to your material, feed method, and downstream setup—whether you’re running it as a standalone primary crusher or building a complete spread with screening and stacking.

The J50 is commonly used as a primary jaw crusher for:

• Quarry & pit operations (hard rock and shot rock)
• Sand & gravel processing
• Recycled concrete & asphalt (RCA / RAP)
• C&D material where you need consistent reduction before screening
• General excavation support where onsite crushing improves cycle time and disposal costs

If your operation regularly handles larger feed sizes or you’re feeding with a loader/excavator and want fewer bottlenecks, the J50 is a strong fit.

Versatile Setup For Different End Goals

Whether your goal is:

• road base
• crusher run
• clean stone
• recycled aggregate
  …the J50 can be configured into spreads with screens and stackers to hit different spec targets. It’s a flexible primary crusher for operations that switch materials and products.
