Dryer calender, pressure roll, calender roll

Dandong Gaoxin Dryer Manufacturing Co., Ltd. produces cast iron dryer rolls and pressure rolls for industrial paper and food processing lines. The largest calender roll offered has a diameter of 1000mm and a face length up to 10,000mm, with hardness exceeding HS70. Pressure rolls can reach 1500mm in diameter and handle line pressures up to 300kg/cm. All cylinder covers are manufactured using resin sand casting with gray iron HT200-300 or graphite cast iron QT400-600, materials selected for thermal stability and wear resistance under continuous operation.

The company's proprietary double-layer and R manufacturing process enhances structural integrity and reduces deformation under load. These rolls are not plated or coated; surface finish relies on precision machining of the cast iron substrate. Standard surface roughness is not specified but typically meets industrial paper machine requirements of Ra 0.8 to 1.6 micrometers. The absence of chrome plating reduces maintenance complexity and avoids delamination risks common in plated alternatives.

These rolls are used by large paper mills in Asia, Europe, and North America for drying and calendering operations. Buyers typically require rolls with custom face lengths and bore diameters to fit existing machine frames. Packaging is wooden crate, suitable for sea freight. Lead time and MOQ are not stated; buyers must confirm production scheduling directly with the supplier. Trade terms are not listed but commonly follow FOB Dandong or CIF terms for international shipments.

Dandong Gaoxin Dryer Manufacturing Co., Ltd. is a private enterprise based in Qianyang Economic Development Area, Dandong, Liaoning, China.
