TRITAN discs are purpose-built for high-consistency (HC) refining where pulp behavior, steam generation, and torque spikes demand rugged engineering. Their geometry and metallurgy maintain bar integrity under high thermal and mechanical stress, enabling consistent fiber development and stable operation.
- Stable, predictable refining under HC steam and vibration
- Optimized bar wear profile for longer service intervals
- Balanced flow and venting to reduce plugging and chatter
- Custom patterns for target freeness and strength development
Disc bodies and bars are produced with alloyed wear-resistant steels refined for high-temperature operation. Heat treatment achieves a tough core with a hardened working surface to resist bar edge rounding and thermal fatigue.
- Alloy design for abrasion and impact in HC duty
- Controlled hardness gradient for crack resistance
- Dimensional stability through thermal cycles
- Surface finish tuned for initial run-in and steady wear
TRITAN patterns balance cutting intensity with steam evacuation to keep the refining gap clean and stable under high torque.
- Structured channels and reliefs to vent steam and fines
- Bar height and width tuned to minimize chatter and plate contact
- Impact-damping transitions that reduce edge chipping
- Root fillet geometry designed to mitigate thermal cracking
- Customizable breaker zones for shive reduction without over-cutting
Expected operational outcomes depend on furnish and stage, but TRITAN designs target measurable stability and fiber development.
- Specific energy: maintained at target with reduced spikes
- Shive reduction: effective breaker zones with controlled fines
- Temperature control: improved venting lowers hot-spot risk
- Run length: extended service intervals through wear profile
- Vibration: minimized through balanced hydraulic loading
- Operating consistency: typical HC range per stage
- Disc diameters: 20–30 inch classes; custom sizes on request
- Bar height/width: application-specific profiles
- Heat treatment: hardened working surface with tough core
- Steam management: integrated reliefs and vent channels
- Mounting: OEM-compatible interfaces and adapters
Request detailed drawings and tolerances via the RFQ form.
Operate within OEM torque and temperature limits. Ensure correct gap control, rotor balance, and steam handling to prevent thermal shock.
- Start-up: verify alignment, warm-up sequence, controlled stock feed
- Monitoring: torque, bearing temperature, vibration, steam pressure
- Safety: lockout/tagout during inspection; use guards and PPE
- Maintenance: inspect wear land, cracks, and mounting integrity at scheduled intervals
Mill: TMP line, secondary HC refiner.
Objective: stabilize specific energy and extend run length.
Outcome: reduced energy spikes and extended disc life before changeout. Operators reported steadier vibration trends after switch to TRITAN pattern with enhanced venting.
