150 TPD Writing Paper Production Line
The writing paper production line is specifically engineered for producing high-quality offset, copy, writing, and newsprint papers across a broad basis weight range. This complete paper mill line integrates a hydraulic headbox with dilution water control and a top wire former on the fourdrinier section, ensuring superior fiber distribution and outstanding sheet formation. The writing paper production line’s extended drainage length with ceramic dewatering elements maximizes water removal before the press section, significantly reducing steam demand.
A five-roll three-nip press arrangement with large-diameter rolls applies gentle dewatering, preserving fiber length and sheet bulk. The writing paper production line integrates vacuum cylinders in the drying section to enhance heat transfer and lower energy consumption. A film transfer sizing station with an air turn system ensures uniform starch application for superior surface strength and printability. Designed for continuous operation, this writing paper production line includes a rope-less tail threading system across the dryer section, minimizing paper breaks and boosting overall efficiency. With robust construction and easy maintenance features, this writing paper production line delivers consistent quality for demanding fine paper applications.
