Double Roller Crusher
Saudi construction — NEOM, Red Sea projects, Jeddah's expansion — needs ASTM-compliant sand from sites running at 60Hz in 45°C+ heat and silica dust. Baichy 2PG double-roller crushers answer: up to 85% sand yield, ~30% lower power draw than impact crushers, wear cost typically under $0.20/t on limestone. No screens to clog, no high-speed rotors to rebuild — two rolls, exact gap, graded sand shift after shift.
1. The Saudi-site reality
• 60Hz grid, 45°C+ ambient: standard machines derate and overheat.
• Abrasive silica dust: cheap seals die within weeks.
• Damp stockpiles: hammer screens blind and plug.
• GCC/ASTM quality gates: reject off-grade fines and oversize.
2. Why the roller wins — benefits, not specs
• Higher yield, less waste: compression-shear crushing converts up to 85% of feed into 0–5mm sand; hammer crushers typically lose 15–25% to over-crushing. More sellable tons per ton of feed.
• Lower power bill: low-speed rolls use ~30% less kWh/t. On a 50t/h line running 20h/day, that is about $1,300/month saved at $0.07/kWh.
• Lower wear cost: roll shells last 8–12 months on limestone versus hammers every 4–6 weeks — fewer changeovers, less downtime.
• Wet tolerance: handles 8–12% moisture without clogging.

3. Engineered for the Saudi site
• 60Hz/400V motors standard; 440V on request.
• IP55 dust-proof motors, labyrinth seals and central lubrication against silica ingress.
• Heat-rated bearings and oversized cooling for 50°C+ operation.
• Online roll-gap adjustment switches M-sand to coarse grit in minutes.
• Compact footprint, simple foundation — drops into existing plants or modular lines.
4. Typical 2PG lineup (limestone, 0–5mm product)
| Model | Feed ≤ | Capacity | Power |
| 2PG610×400 | 60 mm | 5–15 t/h | 2×15 kW |
| 2PG750×500 | 80 mm | 15–35 t/h | 2×22 kW |

| 2PG1000×700 | 120 mm | 40–90 t/h | 2×45 kW |
5. FAQ
Q: Can it make glass-grade silica sand?
A: Yes — rolls handle quartz feed; adjustable gap protects grain shape for 0.6–1.2mm fractions.
Q: Does 60Hz affect selection?
A: No — every 2PG ships with 60Hz motors verified before dispatch; 380V/50Hz also available.
Q: What is the maintenance load?
A: Grease and gap-check per shift; roll resurfacing every 8–12 months on limestone.
