Gyratory crushers are large, robust machines used primarily in the mining and aggregate industries for crushing hard and abrasive materials like ore, limestone, and granite. Here’s a detailed overview of large gyratory crushers:
Key Features of Large Gyratory Crushers:
1. High Capacity
– Designed to handle very large feed sizes (up to 1,500 mm or more).
– Capable of processing thousands of tons per hour (up to 10,000+ tph).
2. Robust Construction
– Heavy-duty frames and components to withstand extreme operating conditions.
– Made from high-strength steel with wear-resistant liners.
3. Superior Crushing Mechanism
– Utilizes a gyrating mantle mounted on an eccentric shaft inside a concave bowl.
– Provides continuous crushing action with high reduction ratios (typically 6:1 to 9:1).
4. Applications
– Primary crushing in mines (copper, gold, iron ore).
– Large-scale aggregate production for construction and road building.
Advantages Over Jaw Crushers:
– Higher throughput for large-scale operations.
– More efficient in processing hard, abrasive materials.
– Continuous crushing action reduces downti.jpg)
compared to jaw crushers’ reciprocating motion.
Common Models & Manufacturers:
– Metso (Nordberg): Superior MKIII series (e.g., MKIII 60-110E).
– Sandvik (CG800i & CS800 series).
– FLSmidth (TS gyratory crushers).
Maintenance & Challenges:
– Requires skilled maintenance due to complex assembly/disassembly.
– High initial capital cost but long-term cost-effective for large operations.
