K-JC 704: Mobile jaw crusher
A popular mid-size tracked jaw and the workhorse for on-site concrete, rock and construction waste recycling.
/ overview
The Komplet K-JC 704 is a compact tracked jaw crusher rated to 80 tph through a 680 × 400 mm jaw, producing a 20–80 mm product. At 12,000 kg it transports easily yet crushes reinforced concrete, brick, rock and mixed demolition material on site, turning waste you would otherwise cart away into reusable aggregate. A tracked base and simple hydraulic jaw adjustment make it fast to set up and run with one operator.
Applications: On-site concrete, brick and construction waste recycling; demolition contractors; landscapers and civil operators processing their own material.
