FIBERIZING SECTION

Our four-roll centrifugal fiberization system integrates premium German engineering to deliver superior mineral wool production efficiency. Key technological advantages include:

• Energy-efficient operation with installed power ≤55kW

• Compact footprint (L×W×H: 3.2×2.1×2.8m)

• Precision dynamic balancing for vibration levels <0.5mm/s

• Optimized mechanical structure with MTBF >8000 hours

• Operator-friendly HMI control interface

System Components:

1. Power distribution cabinet (IP54 rated)

2. Dual-bearing motor base (ISO 1940-1 G2.5 balance grade)

3. Heavy-duty axle box with SKF bearing assemblies

4. Forged alloy steel centrifugal head (HRC 58-62)

5. Closed-loop cooling system (ΔT≤5°C)

6. Automatic oil-mist lubrication (ISO VG 68)

7. Balanced draft ventilation system

Operational Principle:
Molten material (1400-1500°C) is precisely metered onto the centrifugal head via a refractory-lined tilting launder. The high-G force (≈2500g at 6400 rpm) combined with controlled aerodynamic flow (15-20 m/s) achieves optimal fiberization. Simultaneous spray application of:

• Thermoset phenolic resin (10-12% by mass)

• Dedusting oil (mineral-based, 0.5-1.0% application)

The fiber-air mixture is then pneumatically transported to the collection chamber through a patented vortex separation process, achieving >98% dust removal efficiency.

Redundancy Design:
The production-critical nature mandates a 1+1 redundant configuration featuring:

• Hot-standby centrifugal unit with automatic changeover

• Roller cooling system (20°C chilled water, 5bar)

• Centralized lubrication system (per ISO 4406 cleanliness)
