4300 mm Net Paper Width Multi-Cylinder Kraft Paper Machine
The kraft paper machine is an advanced paper making machine specifically engineered for producing high-strength kraft paper from recycled fiber sources. This paper production equipment adopts a multi-wire and multi-cylinder configuration arranged in a double-deck layout, optimizing both forming efficiency and drying capacity for heavy-duty paper grades. As a vital component of paper mill machinery, the kraft paper machine is equipped with dual air-cushion headboxes featuring comprehensive control systems that ensure precise cross-direction profile and consistent basis weight across the entire sheet width.
The kraft paper machine incorporates a forming table with fully ceramic drainage components made from high-purity alumina, mounted on fiberglass-reinforced plastic bases, delivering superior wear resistance and reduced maintenance downtime. The paper forming machine also includes stainless steel suction boxes that undergo specialized heat treatment processes to prevent distortion and ensure long-term reliability. All rolls supplied with the kraft paper machine come as complete assemblies including the roll shell, shaft, bearings with specified brand origin, and robust bearing housings. The wet end is equipped with waterproof auxiliary motors to withstand the challenging moisture-rich environment. The entire kraft paper machine is driven by an AC variable frequency sectional drive system that provides precise speed coordination across all sections, ensuring optimal sheet tension control.
