Equipment recommendations for different ore types

This article will list in detail the ore type, Mohs hardness, core characteristics, recommended crushing process (equipment combination) and the reasons for the recommendation.

1. Ore Type: Granite (Construction)
Mohs Hardness: 6-7
Core Characteristics: Hard rock, high toughness, requires sand production
Recommended Crushing Process (Equipment Combination): Jaw Crusher (Coarse Crushing) → Cone Crusher (Secondary Crushing) → Impact Crusher (Sand Making/Shaping)
Recommendation: Cone crusher resists wear, while impact crusher ensures a satisfactory sand grain size
2. Ore Type: Limestone (Cement Raw Material)
Mohs Hardness: 3-4
Core Characteristics: Medium hardness, high brittleness, finished product size 20-40mm
Recommended Crushing Process (Equipment Combination): Jaw Crusher (Coarse Crushing) → Impact Crusher (Secondary Crushing)
Recommendation: Impact crusher offers high efficiency, produces a fine finished product, and is suitable for cement aggregates
3. Ore Type: Gypsum (Construction)
Mohs Hardness: 1.5-2
Core Characteristics: Soft rock, low hardness, and easy to crush
Recommended Crushing Process (Equipment Combination): Jaw Crusher (Coarse Crushing) → Impact Crusher Hammer Crusher (Fine Crushing)
Recommendation: Hammer crushers offer a high crushing ratio, produce finished products in a single stage, and offer low cost.
4. Ore Type: Iron Ore (for beneficiation)
Mohs Hardness: 5-6
Core Characteristics: Hard rock, requires fine crushing to less than 20mm
Recommended Crushing Process (Equipment Combination): Jaw Crusher (Coarse Crushing) → Multi-Cylinder Cone Crusher (Secondary Crushing) → High Pressure Roller Mill (Fine Crushing)
Recommendation: High pressure roller mill offers high fine crushing efficiency, reducing energy consumption for subsequent ball milling.
5. Ore Type: Pebbles (for sand making)
Mohs Hardness: 6-7
Core Characteristics: Hard rock, smooth surface, requires shaping
Recommended Crushing Process (Equipment Combination): Jaw Crusher (Coarse Crushing) → Cone Crusher (Secondary Crushing) → Impact Sand Making Machine (Sand Making)
Recommendation: Impact crusher’s “rock-on-rock” mode reduces wear and improves sand particle size.

The above are the types of crushers suitable for different types of ores. The specific equipment selection should be determined according to actual needs. For details, please contact Shengbang Machinery WhatsApp +8613949025317 for detailed consultation
