The Large Roller Diameter Equipment by Qinyang Jurui Machinery Equipment Co., Ltd is a game-changer for the paper making industry, offering unrivaled performance and efficiency. This crucial component of high-speed paper machines and specialty paper production lines is engineered to elevate both production efficiency and paper quality. Experience a revolutionary diameter that transcends traditional limits, typically starting from 1200mm and soaring to 2500mm in our advanced models. This breakthrough is achieved through a harmonious blend of rigidity and flexibility, using a composite structure that marries a high-strength substrate with a precision-functional layer. The core is crafted from alloy steel forging or bimetallic composite casting, boasting an impressive tensile strength of ≥900MPa and a yield strength exceeding 650MPa. Enhanced by deep cryogenic quenching paired with ultrasonic frequency induction quenching and tempering, the toughness is augmented by 40%, while surface hardness is meticulously maintained within the golden HRC58-62 range. Even under extreme conditions-up to 150ºC and a linear pressure of 80kN/m-this equipment demonstrates remarkable durability without deformation. The functional layer showcases cutting-edge materials like nano-composite rubber, ceramic metallization coating, and microcrystalline glass coating, achieving a surface hardness of 850-980 Schohs. This remarkable wear resistance surpasses conventional roller bodies by 3-5 times. With friction coefficients precisely managed between 0.12-0.25, complemented by a dynamic medium and high compensation algorithm and a laser online grinding system, the result is a flawless roller surface with a uniformity precision of 0.005mm, ensuring paper uniformity fluctuation of ≤±1.2% as per ISO standards. This equipment excels in critical processes such as wet pressing, surface sizing, and super calendering, ideal for high-value products like food cardstock, glassine release paper, and digital printing substrates. It supports a staggering single-machine production speed exceeding 3000m/min, minimizes paper sheet crushing rates to below 0.3‰, and enhances comprehensive energy efficiency by 18% to 25% compared to smaller diameter equipment, empowering paper enterprises to forge formidable technological barriers in eco-friendly, high-speed, and customized production.
