The CJC-130 jaw crusher is a heavy-duty primary crushing machine for large quarries and mines. This section covers the feed it handles, the products it generates, its industries and the operating and maintenance considerations at this scale.
What Materials Can the CJC-130 Process?
The CJC-130 is built for primary crushing of hard, abrasive rock and mining feed, including:
- Granite, basalt and other hard igneous rock
- Dense mining ore
- Limestone and dolomite
- Large quarried stone and river gravel
The 1,300 x 1,000 mm opening accepts very large run-of-mine blocks, reducing pre-breaking requirements. The compression crushing action makes it well suited to dense, abrasive ore and high-strength rock at heavy tonnage.
What Products Does It Produce?
The CJC-130 produces a coarse, unscreened primary product whose top size is set by the closed side setting (100-280 mm). This material feeds the secondary and tertiary crushers and screens that produce finished aggregate fractions or sized process feed. The coarse CSS range reflects the machine's role as a high-capacity primary: wider settings push throughput toward the upper figure, while tighter settings deliver a more uniform feed to the downstream stages.
Which Industries Use This Crusher?
- Large quarries and high-volume aggregate plants
- Mining and mineral processing operations
- Major construction aggregate production
- Heavy demolition and material recycling at scale
At approximately 42,500 kg with a 160 kW drive, it is selected where a single primary crusher must keep a major plant continuously fed.
How Are Wear Parts Managed?
The fixed and moving manganese steel jaw plates carry the wear. At this tonnage, plate management is a planned maintenance activity: plates are reversed to extend life and replaced during scheduled stops. The cheek plates protecting the chamber side walls are also serviceable items. The toggle plate acts as a mechanical fuse, breaking to protect the machine if uncrushable tramp metal enters the chamber. Maintaining a stock of spare jaw plates keeps the long changeovers a heavy machine requires within planned downtime windows.
What Should Be Considered During Operation?
Choke feeding keeps the chamber full for uniform product and even jaw wear, which is critical at high tonnage. The closed side setting should be confirmed with the hydraulic mechanism after each plate change. Reliable lubrication, correct drive tension and a balanced flywheel are essential for smooth running at the 220 rpm flywheel speed under heavy load. A heavy-duty vibrating grizzly feeder ahead of the crusher scalps fines and meters the feed, protecting the jaws and stabilising the high throughput.
Jaw Crusher Versus Impact Crusher
The CJC-130 reduces material by compression and is the correct primary machine for hard, abrasive rock and ore at high capacity. A primary impact crusher reduces by impact for a cubical product and high reduction ratio, but suits softer limestone feed and wears quickly on abrasive rock. For large, hard-rock mining and quarry duty, the jaw crusher is the durable, lower-wear primary solution, because its compression action processes dense, high-strength material without the rapid blow-bar wear that abrasive ore would inflict on an impact crusher.
