3200mm High Capacity Corrugated Paper Machine

This corrugated paper machine has a net paper width of 3200 mm and a working speed of 130~180 m/min. It adopts AC variable frequency drive and has outstanding advantages such as high dewatering efficiency, low drying energy consumption, and stable and reliable operation. The corrugated paper machine’s wire part adopts a long wire structure and is equipped with high-precision dewatering elements (ceramic dewatering plates or stainless steel panels are optional), resulting in a smooth dewatering curve and high fiber retention. This corrugated paper machine can achieve a press dryness of 38-42%, which can effectively reduce the steam consumption of subsequent drying, reducing steam consumption per ton of paper by 10%-15%. The grouped design of the drying part of this corrugated paper machine allows operators to flexibly adjust the steam pressure and the steam inlet sequence of the drying cylinder according to different basis weights and machine speeds, achieving the dual goals of energy saving and quality. Leizhan provides a full range of services from process design, equipment manufacturing, installation and commissioning to personnel training.

300TPD Double Wire Kraft Paper Machine

This 300tpd kraft paper machine adopts a double-layer wire structure with a wire width of 5500 mm and a net paper width of 5000 mm. Its basis weight range covers 90~220 g/m², enabling stable production of high-strength kraft paper, linerboard, T-paper, and other high-strength packaging papers. The 300tpd kraft paper machine features a compact structure, comprehensive configuration, and a single-layer left-hand machine arrangement for easy operation and maintenance. The dewatering elements of this 300tpd kraft paper machine feature all-ceramic panels (99% Al₂O₃ ceramic), a fiberglass substrate, and a 304 stainless steel housing welded and specially heat-treated. This significantly extends the lifespan of the wire, ensures uniform dewatering, and reduces transverse moisture difference in the paper sheet. The press part of this 300tpd kraft paper machine employs zoned, controllable medium-high roll technology to ensure uniform cross-sectional pressure and reduce transverse moisture difference in the paper sheet (≤±1.0%). The press roll bearings also use well-known domestic brands and are equipped with a centralized lubrication system. Leizhan has provided paper pulping machines to paper mills in many regions and countries, and has extensive industry experience.
