Global Project Case

200TPH Bluestone Crushing Solution: Achieving High Purity & Capacity

Optimized crushing flow designed for high-hardness volcanic rock processing.

1. Project Background

A major construction aggregate supplier in Southeast Asia required a complete production line to process Bluestone (a dense, hard volcanic rock). The primary challenge was the material’s high Mohs hardness and abrasiveness, which typically leads to rapid wear of traditional crusher parts and inconsistent product sizing.

2. The HSM Solution

To ensure long-term stability and low operational costs, HSM engineers designed a multi-stage crushing circuit:

Primary Crushing: PE Series Jaw Crusher for heavy-duty initial reduction of large bluestone boulders.

Secondary Crushing: High-efficiency Cone Crusher, specifically chosen for its ability to handle hard materials with excellent cubic flake shapes.

Impact Crusher

Final Screening: Double Roller Crusher to classify finished products into 0-5mm, 5-10mm, and 10-20mm sizes.
