Key Features of the Alpenfalke Centrifuge System

• Specifically designed for use in the nitrocellulose (NC) dewatering process, ensuring optimal efficiency and precision.
• Basket Construction: Made from duplex stainless steel (DIN – WSt.-Nr 1.4462) for enhanced durability and longevity.
• Slotted Screens: Manufactured using duplex stainless steel (DIN – WSt.-Nr 1.4462) for superior performance.
• Internal (Wet) Components: Constructed with stainless steel (DIN – WSt.-Nr. 1.4571 / AISI 316Ti) to resist corrosion and maintain hygiene.
• Certified Components: A 3.1 certificate according to EN 10204 is provided for all wet parts.
• Substitute Materials: Purchased parts (e.g., nozzles or fittings) not available in stainless steel (DIN – WSt.-Nr. 1.4571 / AISI 316Ti) are replaced with equivalent materials, such as DIN – WSt.-Nr. 1.4305 (AISI 303).
• External (Dry) Components: Constructed from either structural steel with a protective paint coating or stainless steel (DIN – WSt.-Nr. 1.4301).
• Protective Coating: Non-stainless steel components (e.g., stator, drive) are coated with high chemical-resistant paint for durability.
• Non-Metallic Parts: Components in contact with the working medium are made of Teflon PTFE/FEP/PFA (for rotary and static seals) or PVDF (for wipers).
• Surface Finishing: Wet surfaces are ground or electrochemically polished to Ra ≤ 0.8 μm, ensuring smoothness and hygiene.

Key Component Descriptions of the Alpenfalke Centrifuge System

1. Centrifuge Housing: Functions as an oil tank with mounting points for the bearing assembly, rotor drive, hydraulic pump, and other components. The robust design reflects Alpenfalke’s commitment to quality.
2. Bearing Assembly: Features a main body, two shafts, outer rolling bearings, inner sliding bearings, an inner pulsation piston mechanism, oil-lubricated bearings, and a labyrinth rotary seal with compressed air protection for the working area.
3. Basket Assembly: Includes inner and outer baskets with slotted screens and non-metallic wipers for efficient material separation, designed to Alpenfalke’s high-performance standards.
4. Rotor Drive: Comprises a tension plate, belt transmission, and an asynchronous electric motor (XX01AM10) with thermistors and temperature sensors for bearings. The motor is compatible with frequency converters, a hallmark of Alpenfalke engineering.
5. Pulsation Drive: Includes a hydraulic pump, an electric motor with thermistors, temperature transmitters for bearings, hydraulic elements, oil filters, and an oil heat exchanger for water-based cooling/heating. It lacks hydraulic-mechanical pulsation speed regulation but supports frequency converter integration.
6. Stator: Features internal partitions, an external basket flushing system, a working area flushing system, a product outlet channel, and a flushing system for the outlet area. Alpenfalke’s design ensures optimal process flow.
7. Stator Front Cover: Includes a manually operated manhole with a safety pressure lock, sight glass, suspension filling pipe, and quick-rinse pipes for basket screens.
8. Safety and Monitoring Systems:
   • Manhole safety lock position sensors.
   • Centrifuge vibration sensor.
   • Centrifuge basket speed sensor.
   • Inner basket pulsation sensor.
   • Temperature transmitters for rotor bearings.
   • Oil temperature and minimum oil level sensors in the tank.
9. Electrical Installation: Wiring to terminal boxes for seamless integration.
10. Measurement Sensors: Equipped for speed, pusher movement, vibration, temperature, oil level, and oil temperature monitoring.
