Refiners for Mechanical Fiber Treatment
Low and high consistency models engineered for robust operation, precise control, and compatibility with Prometals discs.
Advanced Control & Automation

Achieve stable refining with integrated instrumentation and control:

  • Real-time sensors: motor load, vibration, temperature, consistency (LC/HC), and plate gap (where applicable).
  • Closed-loop load/plate-gap control for target refining intensity and specific edge load (SEL) management.
  • PLC/SCADA integration via Modbus/TCP, Profibus, or Ethernet/IP; historian-ready tags.
  • Safety: interlocks for seal water, bearing lubrication, and emergency stops with permissive logic.
  • Remote support and recipe management for grade changes and startups.
Performance & Capacity

Engineered for high throughput and energy efficiency:

  • Low Consistency (LC) models: typical capacity 50–900 m³/h per machine, motor power 75–800 kW.
  • High Consistency (HC) models: typical capacity 5–80 t/d, motor power 110–1500 kW.
  • Energy: optimized hydraulics and disc patterns reduce kWh/t at target freeness and strength.
  • Turn-down: stable operation at 50–100% of nominal flow with consistent plate loading.
  • Maintenance windows designed for rapid plate change and seal inspection.

Sizes: LC refiners DN 300–1200; HC refiners rotor diameters 400–1200 mm.
Motor Power: 75–1500 kW depending on model and duty.
Connections: Flanged inlets/outlets; seal water, lubrication, and instrumentation ports standardized.
Operating Limits: Design pressure up to 10 bar(g) (LC) and 16 bar(g) (HC); temperature up to 120°C.
Materials: Carbon steel frame; stainless wetted parts available; wear components with proprietary heat treatment.
Compliance: CE and local electrical standards upon request.
