Crushers for lumpy clinker are essential equipment in cement plants and other industries where clinker processing is required. Clinker is a hard, nodular material produced during the cement kiln stage, and it often forms lumps that need to be crushed before further grinding or use.
Types of Crushers Suitable for Lumpy Clinker:
1. Hammer Crushers
– Working Principle: Uses high-speed rotating hammers to impact and break clinker lumps.
– Advantages: Effective for medium-hard materials like clinker, simple structure, easy maintenance.
– Limitations: High wear on hammers due to abrasiveness of clinker.
2. Roll Crushers (Double Roll Crushers)
– Working Principle: Two counter-rotating rollers crush clinker lumps by compression.
– Advantages: Lower fines generation compared to hammer crushers, suitable for softer or moderately hard materials.
– Limitations: May struggle with very hard or large lumps unless designed for heavy-duty applications.
3. Jaw Crushers
– Working Principle: Uses a fixed and movable jaw plate to crush clinker by compression.
– Advantages: Robust design, good for primary crushing of large lumps.
– Limitations: Higher maintenance due to abrasive wear on jaw plates.
4. Impact Crushers (Horizontal Shaft Impactors)
– Working Principle: High-speed rotors with blow bars crush clinker by impact force.
– Advantages: Efficient size reduction with adjustable output size via aprons/grates.
– Limitations: Wear-prone components due to abrasive nature of clinker..jpg)
5. Single-Roll Crushers
– Suitable for smaller capacities but less common than double-roll crushers.
Key Considerations When Selecting a Clinker Crusher:
– Hardness & Abrasiveness: Clinker is abrasive; choose wear-resistant materials (e.g., manganese steel liners).
– Lump Size & Feed Rate: Ensure the crusher can handle maximum lump dimensions (typically 50–100 mm).
– Capacity Requirements: Match throughput (tons/hour) with plant needs.
– Maintenance & Durability: Opt for designs with easy access to replaceable parts like hammers, rollers, or jaws.
Best Choice:
For most cement plants handling lumpy clinker:
– A heavy-duty hammer crusher is commonly used due to its efficiency in breaking large lumps.
– For finer control and lower fines generation, roll crushers may be preferred.
– Jaw crushers are ideal if primary crushing of very large lumps (>100 mm) is needed before secondary crushing.
