Stone Crusher: Types, Applications, and How a Quarry in Canada Boosted Efficiency‌

Stone crushers are the backbone of mining and construction industries, transforming raw boulders into usable aggregates.  In this article, we explore the technical specifications of modern crushers and share a real-world case study from a Canadian quarry.

 ‌Key Features & Benefits‌

‌High Crushing Ratio‌: Reduces 1000mm rocks to 20mm gravel in a single pass.

‌Mobility‌: mobile crusher enable on-site processing, slashing transport costs.

‌Smart Controls‌: IoT sensors monitor wear parts and predict maintenance needs.

‌ Applications‌

‌Road Construction‌: Produces uniform gravel for asphalt mixing.

‌Concrete Production‌: Crushed limestone as a primary ingredient.

‌Mine Tailings Recycling‌: Repurposes waste rock into eco-friendly building materials.

 ‌Case Study: Lafarge Quarry, Ontario‌

‌Client Background：‌

Lafarge, a leading Canadian construction materials supplier, struggled with low output and frequent downtime at their granite quarry.

 ‌Challenges‌

Existing jaw crusher produced uneven particle sizes (30% oversize).

Downtime costs exceeded $15,000 per hour due to belt failures.

Strict noise regulations limited operational hours near residential areas.

‌

We deployed a PEX-250X750 ‌Hybrid Jaw Crusher‌ with:

‌Dual Power System‌: Diesel-electric operation reduced noise by 40%.

‌Auto-Adjustment‌: Real-time gap calibration via hydraulic wedges.

‌Modular Design‌: Quick replacement of wear plates during shifts.

 ‌Results：‌

‌Output Increased by 35%‌: From 150 to 410 tons/hour.

‌Downtime Reduced by 70%‌: Predictive maintenance alerts cut unplanned stops.

‌Regulatory Compliance‌: Noise levels stayed below 75 dB(A), permitting 24/7 operations.

‌Common Issues & Expert Tips‌

‌Problem‌: Metal contamination from conveyor belts.

‌Fix‌: Install metal detectors and self-cleaning magnets.

‌Problem‌: Dust emissions exceeding 50 mg/Nm³.

‌Fix‌: Integrate water spray nozzles and baghouse filters.
