Bluestone (Mohs hardness 3-4) is a medium-hardness material. Bluestone crushing equipment combination should be selected based on output, output particle size, and process requirements. A reasonable combination of coarse crushing, medium and fine crushing, and sand making equipment is necessary. Due to the high hardness of bluestone, it is recommended to use a wear-resistant jaw crusher for coarse crushing, a cone crusher for medium and fine crushing, and finally a vertical shaft impact crusher for shaping to ensure good finished product particle shape.

 

1. Jaw Crusher (Coarse Crushing)

 

Applicable Scenarios: Processing large pieces of bluestone (feed size ≤1200mm), compressive strength ≤320MPa.

 

 

Selection Parameters:

Feed opening width: 430-1300mm (JC series jaw crusher).

 

Motor power: 75-400kW, hourly output 50-2000 tons.

 

Advantages: Simple structure, low maintenance cost, suitable for primary crushing.

 

2. Cone Crusher (Medium and Fine Crushing)

 

Applicable Scenarios: Medium and fine crushing with high particle shape requirements (discharge particle size 5-20mm).

 

 

Selection Parameters:

Feed Size: 65-370mm (GPY series single-cylinder cone crusher).

 

Power: 90-750kW, output 45-2188 tons per hour.

 

Advantages: Layered crushing principle, uniform finished product particle shape, long service life of wear parts.

 

3. Vertical Shaft Impact Crusher (Fine Crushing/Shaping)

 

Applicable Scenarios: Sand making or shaping (discharge particle size 1-5mm), when high particle shape quality is required.

 

Selection Parameters:

Feed Size: ≤60mm (PLS series crusher).

 

Power: 30-500kW, output 24-1100 tons per hour.

 

Advantages: Utilizes stone-on-stone/stone-on-iron principle, resulting in well-graded finished sand with low needle-like and flaky content.

 

Bluestone Crushing Production Line Configuration Recommendations:

 

Low Output (<100 tons/hour): Jaw crusher + impact crusher/hammer crusher.

 

Medium-to-high Output (≥100 tons/hour): Jaw crusher + cone crusher + sand making machine.

 

Layout Optimization: Designed with reference to equipment spacing and material flow direction to reduce energy consumption.
