Drawing on decades of expertise across stock preparation, wet-end forming, pressing, drying, and reeling technologies, Leizhan delivers robust paper machines that convert both virgin and recycled fibers into high-quality kraft paper, testliner, and fluting medium.

As the first critical unit in the stock preparation system, the Bale Breaker (also referred to as a Bale Opener or Dry Screening System) plays a pivotal role in loosening compressed waste paper bales and removing dry impurities before the material enters the hydrapulper.

The efficient and continuous removal of heavy contaminants is essential for both product quality and equipment protection. Leizhan offers the Slag Lifting Machine, an automated heavy-reject extraction system engineered to integrate seamlessly into modern pulping lines.

Leizhan Paper Machinery has developed a robust portfolio of fiber processing solutions, among which the Hydrapurger (Impurity Separator) stands out as a vital component in integrated waste paper pulping systems.

The Fiber Deflaker is specifically designed to enhance the uniformity and quality of pulp by breaking down fiber clumps and improving the dispersion of cellulose fibers within the pulp slurry.

The kraft paper making machine produced by Leizhan can meet various specific needs for producing kraft paper for paper mill. The machine is equipped with advanced technology and functions to efficiently produce high-quality kraft paper.

The sizing machine is used in the paper production process to apply a sizing agent to the surface of paper. The sizing agent improves the paper’s properties, such as its resistance to water, ink absorption, and overall strength.

Felt is an integral component in the paper-making process. As a non-woven fabric made from fibers, felt is used extensively in paper mills for various applications, particularly in the forming and pressing sections of the paper machine.

In order to optimize the production process, Leizhan provides customers with a complete set of writing paper making machine line solutions, including all pulping equipment, to ensure the efficiency of the production process and the high quality of paper.

The Reject Separator processes this material by separating valuable fibers from contaminants, allowing the fiber-rich portion to return to the production line while concentrating the unwanted materials for convenient discharge and further treatment.

Manufacturing craft packaging paper involves chemically processing wood chips using a blend of sodium hydroxide and sodium sulfide. This method enhances the paper’s durability while improving its resistance to tearing and moisture.

An eccentric pulper is purpose-built equipment deployed at the first processing stage of paper making. Its core job is to disintegrate industrial raw materials into usable pulp, which goes on to further processing to create finished paper goods.
