When selecting a crusher for iron ore with a capacity of 1000 tons per hour (t/h), several factors must be considered, including the type of iron ore (magnetite, hematite, etc.), feed size, required product size, abrasiveness, and moisture content. Below are the most suitable crusher options for this capacity:
1. Primary Crushing Options
For large-scale iron ore processing (1000 t/h), primary crushers must handle high throughput and hard, abrasive material.
# A. Gyratory Crusher
– Best for: Very large feed sizes (up to 1500 mm).
– Advantages:
– High capacity (can exceed 5000 t/h in some models).
– Robust design for abrasive materials like iron ore.
– Lower maintenance compared to jaw crushers at high capacities.
– Disadvantages: Higher initial cost and complex installation.
# B. Jaw Crusher (Large-Scale)
– Best for: Moderate feed sizes (up to 1200 mm).
– Advantages:
– Simpler structure than gyratory crushers.
– Good for primary crushing in medium-hard ores.
– Disadvantages: Lower capacity compared to gyratory crushers at this scale.
2. Secondary & Tertiary Crushing Options
After primary crushing, secondary/tertiary crushers further reduce the size.
# A. Cone Crusher (HPGR or Hydraulic)
– Best for: Secondary/Tertiary crushing (feed size 250–300 mm → output 20–50 mm).
– Advantages:
– High reduction ratio.
– Energy-efficient compared to impact crus.jpg)
s for hard ores.
– Example Models: Metso MP1250, Sandvik CH890.
# B. High-Pressure Grinding Rolls (HPGR)
– Best for: Energy-efficient comminution of iron ore.
– Advantages: Lower energy consumption than conventional crushers/mills.
# C. Impact Crusher (For Softer Ores)
– Not typically recommended for hard iron ores due to high wear rates.
