High Performance Kraft Paper Machine

High Performance Kraft Paper Machine

Kraft paper machine is a kind of equipment used to make kraft paper. The kraft paper machine can make thick cardboard from paper pulp, which has the characteristics of high strength, water resistance and wear resistance. It is widely used in packaging, construction and other fields.

Supplying Press Rolls for Paper Mills

The press rolls supplied by Leizhan feature a stainless steel roll shell, with the shell thickness determined based on the required rigidity and strength. Putting these press rolls into operation enables rapid separation of the wet paper web from the felt; since moisture does not migrate back into the felt or the web, rewetting is effectively prevented, thereby further enhancing dewatering performance. The press rolls supplied by Leizhan are manufactured from high-strength alloy steel or specialized materials, featuring excellent wear and pressure resistance on the roll surface. Equipped with a doctor blade assembly, these press rolls prevent surface clogging and the accumulation of debris, thereby maintaining surface cleanliness and extending the intervals between grinding operations. Leizhan supplies complete press roll assemblies—including the roll body, shaft, bearings, and bearing housings—ensuring precise component fit and consistent operational performance. Leizhan not only supplies pulp and paper machinery in various specifications but also offers spare parts for various types of paper mill equipment.

Paper Industry 2400mm Underfeed Rewinder

This 2400mm underfeed rewinder introduces the paper web from below, offering operators better visibility and making the threading process more intuitive and seamless. It also facilitates easier handling of sheet breaks, making it particularly well-suited for medium-to-high-speed operations (500 m/min). Combined with the precise control of pneumatic actuators, the 2400mm underfeed rewinder ensures a smooth build-up of threading tension, effectively reducing sheet breaks and web fluctuations during the initial winding phase. This 2400mm underfeed rewinder features a dynamic balance rating of 2.5G at an operating speed of 600 m/min. Equipped with support rolls (diameter: φ510 mm) that have undergone precision dynamic balancing, it ensures minimal vibration during high-speed operation, resulting in uniform tightness from the core to the outer layer and flat, neatly aligned roll ends. With a maximum capacity of φ1500 mm for both parent rolls and finished rolls, the 2400mm underfeed rewinder meets the requirements for continuously rewinding large-diameter rolls, thereby reducing the frequency of roll changes and minimizing downtime. If you are looking for finished-product rewinding equipment that offers stable operation and superior rewinding quality, please contact Leizhan for detailed technical solutions and commercial quotations.

Pulping Equipment Chain Conveyor for Sale

The chain conveyor from Leizhan features slats formed via a single-step stamping process; these offer high strength and impact resistance, capable of withstanding the continuous, heavy-duty impact of waste paper bales and loose waste paper. The chain conveyor utilizes an enclosed design that effectively prevents fine material from leaking through the gaps between slats, thereby keeping the operating area clean. The chain system of this chain conveyor utilizes a double-row roller traction chain structure; the hollow roller pin design allows lubricant to flow from the pin to the bushing and the wear-resistant tin-zinc-copper liner, significantly extending the chain’s service life. The chain conveyor features a V-shaped material deflector (exceeding the effective conveying width of 400 mm), which effectively increases material throughput and reduces the accumulation and jamming of waste paper during transport. Leizhan supplies pulp and paper machinery to numerous paper mills worldwide and possesses extensive industry experience; please feel free to email me your requirements to obtain details and a quote.
