Selecting the best crusher and conveyor for coal depends on factors like coal type, moisture content, required throughput, particle size, and environmental conditions. Below are the top recommendations:
1. Best Crusher for Coal
# Primary Crushers (Large Coal Lumps → Medium Size)
– Double Roll Crusher
– Best for soft to medium-hard coal with high moisture.
– Low fines generation, good for sticky coal.
– Example: McLanahan Double Roll Crusher.
– Jaw Crusher
– Suitable for hard and abrasive coals.
– High capacity but generates more fines.
– Example: Metso Nordberg C Series Jaw Crusher.

# Secondary Crushers (Medium Size → Fine Coal)
– Impact Crusher (Horizontal Shaft Impactor – HSI)
– Good for reducing coal to smaller sizes (0-20mm).
– High throughput but wears faster with abrasive coal.
– Example: Terex Finlay I-140 Impact Crusher.
– Hammer Mill Crusher
– Best for friable coal with low abrasiveness.
– Produces uniform size but high fines generation.
– Example: Williams Patent Crusher Hammer Mill.
# Tertiary/Quaternary (Fine Crushing & Screening)
– Cone Crusher (f.jpg)
harder coals) or Vertical Shaft Impactors (VSI) (for shaping).
2. Best Conveyor for Coal
# Belt Conveyors (Most Common Choice)
– Fabric Reinforced Belts – For general coal transport (EP/Nylon belts).
– Steel Cord Belts – For long-distance, high-tension applications.
– Recommended Brands:
– Continental ContiTech (Steep Incline Conveyors for space-saving).
– Fenner Dunlop (Fire-resistant belts for underground mining).
# Specialized Conveyors
– Pipe Conveyors – Enclosed design to prevent dust & spillage.
– Screw Conveyors – For short-distance, fine coal transport (avoid abrasive coals).
Key Considerations When Choosing:
✔ Coal Properties: Moisture, abrasiveness, size requirements.
✔ Throughput Capacity: Jaw/roll crushers for high tonnage
