Facing Paper Machine for Gypsum Board Liner
The facing paper machine is specifically designed for producing 80‑240 g/m² gypsum board liner. It features a triple‑wire forming section with air‑cushion headboxes, a press section comprising three vacuum pickup units, one vacuum press, and two large‑diameter roll presses. The drying section of facing paper machine consists of 10 φ1500 VAC cylinders and 34 φ1800 dryer cylinders arranged in a flexible sequence, followed by a horizontal reel and AC sectional drive with variable frequency control. This facing paper machine ensures excellent sheet formation, high dewatering efficiency, and stable operation for heavy‑weight linerboard production.
