PRIMARY COMPRESSION CRUSHING OF ABRASIVE MATERIAL
If you can explain how a nutcracker works you can essentially envision the operation of a Liberty Jaw Crusher.
Inside the chamber there are two jaws. One is fixed while the other constantly moves back and forth. This action compresses the rock causing it to break. Rocks stay in the jaws until they are small enough to pass through the bottom gap.
Superior builds more than a dozen models of the Liberty Jaw Crusher:
- Feed Size: Up to 47″ (1,194mm)
- Product Size: 15″ – 5″ (380mm – 125mm)
- Production Rate: Up to 1,595 STPH (1,446 MTPH)
2-Year / 6,000 Hour
The Liberty Jaw Crusher comes backed by a rock-solid 2-year / 6,000-hour warranty against manufacturer defects.
