2500 mm Kraft Paper Machine For Paper Mill
The kraft paper machine is specifically engineered for producing high-strength kraft paper and corrugating medium across a wide basis weight range. This paper mill machine features a double-wire forming section with an air-cushion headbox that ensures excellent fiber distribution and uniform formation. The kraft paper machine integrates a vacuum suction transfer roll followed by two large-diameter press rolls that apply gentle yet effective dewatering, preserving fiber strength and sheet bulk.
A multi-cylinder dryer section with twenty-four dryer cylinders arranged in three groups provides efficient drying, while an inclined sizing machine applies surface treatment for enhanced strength properties. The kraft paper machine also includes a two-roll calender for improved smoothness and a horizontal pneumatic reeling machine for efficient winding. Designed for continuous operation with AC variable frequency sectional drives, this kraft paper machine delivers consistent quality and high output for demanding packaging applications.
