A stone crusher is essential for granite rock crushing jobs, as granite is a hard, abrasive material that requires robust machinery for efficient processing. Here’s a breakdown of the best crushers for granite crushing and key considerations:
Best Crushers for Granite Rock Crushing
1. Jaw Crusher (Primary Crushing)
– Ideal for initial granite reduction (from large blocks to smaller pieces).
– High compressive strength (~250-350 MPa) makes granite suitable for jaw crushing.
– Models: PE Series (China), CJ Series (Sandvik), Nordberg C Series (Metso)
2. Cone Crusher (Secondary/Tertiary Crushing)
– Best for producing fine aggregates (1000 tph).
Key Considerations
– Hardness & Abrasiveness: Granite wears out crusher parts quickly—use high-manganese steel or tungsten carbide liners.
– Feed Size: Jaw crushers handle large blocks (~1m), while cone/impact crushers work best with smaller feed (<250mm).
– Output Requirements: Adjust closed-side settings (CSS) on cone/jaw crushers to control final product size (0-5mm, 5-20mm, 20-40mm).
– Mobility: For temporary sites, consider mobile crushers (track-mounted jaw/cone crushers).
Typical Granite Crushing Process
1. Primary Crushing: Jaw/Gyratory → Reduce to ~150mm.
2. Secondary Crushing: Cone/Impact → Further reduce to ~30mm.
3. Tertiary Crushing/VSI Sand Making: For manufactured sand (<5mm).
