McCloskey J45 Jaw Crusher Overview
The McCloskey J45 Jaw Crusher delivers high production performance with a robust design suited for heavy-duty material handling. Known for its durability and output, the J45 is a trusted choice for aggregate producers, contractors, and recyclers who demand reliability and throughput from their crushing equipment.
Key Features
At the heart of the J45 is a true 1140mm x 688mm (45” x 27”) jaw chamber — offering one of the largest jaws in its class. This machine combines power and precision with a C9 / C9.3 Caterpillar engine and an advanced pre-screening system that boosts efficiency by reducing wear on the jaw and allowing fine materials to bypass.
The heavy-duty bofar design and steep pan feeder chutes help minimize material build-up and sticking, particularly in wet or sticky conditions. With features like a hydraulically folding main conveyor and an adjustable discharge height, the J45 adapts well to varied on-site demands.

-
Quarry operations and large-scale aggregates

Concrete recycling and hard rock crushing
