Crushing equipment for carbonates (such as calcium carbonate, magnesium carbonate, or dolomite) must be selected based on the material’s hardness, abrasiveness, moisture content, and desired particle size. Here are some common types of crushing equipment used for carbonate minerals:

1. Jaw Crusher
– Best for: Primary crushing of large carbonate rocks (e.g., limestone, marble).
– Advantages: High reduction ratio, simple structure, reliable operation.
– Output Size: 10–350 mm (adjustable).
2. Impact Crusher (Horizontal & Vertical Shaft)
– Best for: Medium to fine crushing of softer carbonates (e.g., calcium carbonate).
– Advantages: Produces cubical-shaped particles, good for aggregates and industrial fillers.
– Output Size: 0–20 mm (adjustable).
3. Cone Crusher
– Best for: Secondary/tertiary crushing of harder carbonates (e.g., dolomite).
– Advantages: Higher efficiency than jaw crushers for finer outputs.
– Output Size: 5–50 mm (adjustable).
4. Hammer Crusher
– Best for: Soft to medium-hard carbonates with low moisture content.
– Advantages: High throughput, suitable for fine grinding applications.
– Output Size: 0–5 mm (for ultra-fine applications).
5. Roller Crusher
– Best for: Fine crushing and grinding of carbonates into powders (e.g., GCC – Ground Calcium Carbonate).
– Advantages: Low dust generation, energy-efficient for fine milling.
– Output Size: 0–1 mm (adjustable).
6. Ball Mill / Raymond Mill (For Ultra-Fine Grinding)
– Best for: Producing micron-sized powders (used in paints, plastics, paper industries).
– Advantages: High precision in particle size control.
Key Considerations When Choosing Equipment:
– Material Hardness → Jaw/Cone crushers for hard carbonates; Impact/Hammer for softer ones.
– Moisture Content → Wet crushing may require special designs.
– Desired Particle Size → Coarse crushing vs. fine grinding.
– Production
