Granite is one of the hardest natural stones. Choosing the right crusher is essential to ensure efficiency, productivity, and cost-effectiveness in mining, construction, or aggregate production. In this article, we explore the best crushers for granite crushing.
Why Is Granite Difficult to Crush?
Granite is an igneous rock composed mainly of quartz (hardness 7 on the Mohs scale) and feldspar, making it highly abrasive and resistant to crushing. Its high compressive strength (between 100-300 MPa) requires robust crushing equipment that can handle heavy-duty operations without excessive wear.
Five Crushers for Granite Crushing
Jaw Crusher
Advantages:
High crushing ratio
Simple structure, easy maintenance
Handles large feed sizes (up to 1500 mm)
Disadvantage: Not ideal for final product shaping.
Cone Crusher
Advantages:
Produces well-shaped, uniform particles
High efficiency with less wear than impact crushers
Adjustable discharge size
Disadvantage: Higher initial cost compared to jaw crushers.
Impact Crusher
Advantages:
Excellent particle shape for construction use
Good for medium-hard granite varieties
Disadvantage: Higher wear on blow bars due to granite’s abrasiveness.
Gyratory Crusher
Advantages:
Higher throughput than jaw crushers
Continuous crushing action
Disadvantage: More expensive and complex to maintain.
Vertical Shaft Impact Crusher (VSI)
Advantages:
Produces high-quality manufactured sand
Good for final product shaping
Disadvantage: Not suitable for primary crushing.
Maintenance Tips for Granite Crushing
Use high-quality, wear-resistant liners and blow bars.
Regularly check and adjust crusher settings for optimal performance.
Monitor feed size to prevent blockages and excessive wear.
Granite’s hardness and abrasiveness demand durable and efficient crushers. Jaw and gyratory crushers excel in primary crushing, while cone crushers and VSI crushers are best for secondary and fine crushing. Selecting the right crusher will maximize productivity and minimize operational costs in granite processing.
