Hi! How can I help you?
The combination of premium materials, optimized design, advanced manufacturing processes and technological differentiation constitutes the foundation of Pegasus Refining Concept.
Operating at consistency levels of 2-8% compared to traditional high-consistency methods, Pegasus refining plates serves as the heart of this process, where precise mechanical treatment of fibers occurs through controlled compression and shearing forces between rotating disc surfaces.
The technology addresses critical industry needs for energy efficiency, fiber quality optimization, and operational flexibility. Pegasus LC refining systems can achieve energy savings of 142 kWh/t compared to conventional high-consistency refining while maintaining superior fiber development characteristics.
The future of mechanical pulping lies in the continued development and optimization of low-intensity refining technologies. As the industry faces increasing pressure for sustainability and energy efficiency, these advanced systems provide a viable pathway for achieving environmental and economic objectives while maintaining or improving product quality.
The evidence strongly supports the adoption of low-intensity mechanical fiber treatment as a standard practice in modern pulp and paper manufacturing, with significant potential for further development and optimization through continued research and technological advancement.
Intensity Simulator (SEL)
The calculation of refining intensity is typically evaluated using the Specific Edge Load (SEL) equation, expressed as a function of power, speed, and plate geometry.
SEL = (Total Power - No-Load Power) / (RPM × Cutting Edge Length).
The intensity dictates the severity of the impact each fibre experiences during its residence time in the refining zone. If the intensity is pushed too high relative to the fibre's inherent burst strength, there is a critical risk of excessive fibre cutting rather than the desired surface fibrillation.
To illustrate this mathematical relationship, consider a standard industrial input scenario: an applied motor power of 1,200 kW operating alongside a no-load power (parasitic mechanical and hydraulic losses) of 250 kW, with a rotational speed of 600 RPM and a plate specification delivering a Cutting Edge Length (CEL) of 30.0 km/rev.
This specific configuration yields a resulting SEL of 3.17 J/m. In the context of delicate fibers, 3.17 J/m constitutes a high-intensity state that poses a severe, immediate risk of severing the fiber backbone, thereby destroying tear strength and overall sheet integrity.
Managing this intensity requires precise micro-geometry and an understanding of how micro-features influence the ultimate kilowatt-hours per ton (kWh/ton) metric.
