What Is It? Working Principle
As a specialized sand making machine, hydraulic roll crusher comprises two rotating rolls, a hydraulic system, transmission, and frame. Its sand-focused working principle:
Dual rolls rotate oppositely at adjustable speeds (motor-reducer driven).
Raw materials (pebbles, granite, construction waste) are squeezed into sand by high-pressure rolls.
Core hydraulic system: Precisely adjusts roll gaps (controls sand size) and offers overload protection—relieves pressure for uncrushables, then resets quickly.
Key Advantages
Vs. traditional sand makers (impact, vertical shaft types), it has unique benefits:
1. Precise Particle Control
Stepless, high-precision roll gap adjustment meets strict grading demands. Minimizes overcrushing, boosting qualified sand yield.
2. High Efficiency, Low Energy Use
High-pressure squeezing achieves large crushing ratio in one pass. Energy consumption per ton is 20%-30% lower than traditional models, cutting costs.
3. Stable & Durable
Stable hydraulic pressure reduces vibration/noise. Wear-resistant alloy steel rolls handle hard materials; overload protection lowers maintenance costs.
4. Versatile & Eco-Friendly
Processes natural stones/construction waste (recycling-friendly). Closed, sealed chamber reduces dust, meeting环保 standards.
Ideal Applications
Widely used in sand production:
Construction: Fine/medium sand for concrete, mortar, decoration.
Infrastructure: Qualified sand for roads, bridges, airports.
Mining: Ore crushing into sand-sized particles.
Waste recycling: Construction waste to recycled sand.
Perfect for large sand yards, recycling plants, and infrastructure projects.
Quick Maintenance
Regularly check hydraulic oil level/quality; replace as manual.
Inspect pipelines for leaks; repair promptly.
Lubricate bearings/transmission parts regularly.
Clean chamber and check roll wear; repair/replace if needed.
Final Take
For high-efficiency, precise sand making (especially hard materials), this crusher is top for medium-to-large projects. Have questions on selection? Comment below! Share with peers!
