1. Wide pressure zone static pressure dewatering
The traditional instantaneous narrow pressure zone is replaced with a wide pressure zone (150-350mm) for prolonged compression, ensuring smooth moisture extrusion.
2. Core structure
The shoe roller (hydraulic shoe plate + elastic shoe cover) cooperates with the counter roller, achieving low-friction operation through oil film lubrication.
3. Pressure characteristics
The pressure curve is smooth, with a low peak value (<6MPa), allowing for precise regulation and reducing the risk of crushing.
Main application scenarios
★ High-speed cultural paper machine: Newsprint, art paper, etc., suitable for speeds of 1000-2000m/min.
★ Mainstream paperboard machines: Corrugated board, containerboard, and cardboard, with high linear pressure and significant dewatering requirements.
★ Toilet paper machine: Special flexible shoe press, achieving both high dryness and high bulkiness.
★ Specialty paper/pulp board: Production of decorative base paper, industrial paper, and pulp board.
★ Etrofitting old paper machines: An ideal choice to enhance dryness and speed, while reducing energy consumption.
Core strengths
★ High dehydration efficiency: the dryness of the press cake increases by 2-4%, and the energy consumption for drying decreases by over 8%.
★ Excellent paper quality: high bulk, small difference between both sides, and shallow felt pattern.
★ High linear pressure with low compression ratio: The linear pressure can reach 2000kN/m, which is evenly distributed and not prone to collapse.
★ Stable operation: Adapted to ultra-high speed, with a 15-30% increase in production capacit
★ Flexible adaptation: Hydraulic zoning design, suitable for both new construction and renovation.
Summary
The shoe press utilizes wide-nip static pressing technology to enhance dewatering efficiency while significantly improving paper quality and operational economy.
