In the paper manufacturing process, the sizing machine plays a pivotal role in determining the end-use properties of the paper. By applying surface sizing agents such as starch or synthetic polymers, this unit enhances surface strength, printability, and resistance to liquids.

The Carton Paper Making Machine, or the Corrugated Board Production Line, is the technological marvel that transforms raw materials into the versatile, robust, and essential material we know as corrugated cardboard.

By optimizing washing performance, Leizhan’s High-Speed Stock Washer ensures higher pulp purity, reduced chemical consumption, and improved wastewater management—key factors in meeting today’s industrial and environmental standards.

Introduction In the paper industry, the uniformity and stability of pulp directly affect paper quality and production efficiency. The Agitator is specifically designed for pulp chests, maintaining the pulp liquid in a suspended state through periodic circulating mixing.

Leizhan’s M.C. Hydrapulper is a heavy‑duty pulping unit designed for continuous and batch paper pulp preparation in modern paper mills. Engineered for efficiency, low maintenance, and consistent fiber quality.

Leizhan Company’s chain conveyors are engineered specifically for the demanding environment of paper pulp mills. They transport bulk waste paper and packaged goods across short and long distances with reliability, heavy-duty capacity, and low maintenance.

Producing whiteboard paper requires specific formation, coating, and drying processes to deliver a smooth, uniform and receptive surface. The whiteboard paper making machine is the integrated production line and set of equipment that enables mills to manufacture this grade at commercial volumes.

Leizhan’s Kraft Paperboard Making Machine is a purpose-built production line for manufacturing high-strength kraft paperboard used in packaging, corrugated medium, boxboard, and specialty industrial papers.

Among the various equipment used in pulp processing, the Ragger stands out as a specialized and highly effective solution for removing twisting impurities from pulp. It plays an essential role in ensuring the purity and quality of pulp before it proceeds to subsequent processing stages.

Leizhan Brown Kraft Paper Machine is a modern paper making equipment designed for the production of high-strength Kraft Paper. It is suitable for the manufacture of packaging kraft paper, composite base paper, food-grade oil-proof paper and other products.

In the process of waste paper recycling and pulping, light and heavy impurities (such as plastic pieces, metal chips, sand and gravel, adhesives, etc.) in the raw materials will seriously affect the pulping quality and equipment life. The Hydrapurger can remove the light and heavy impurities efficiently.

As a leading domestic paper pulping equipment manufacturer, Leizhan's independently developed Drum Screen has become a benchmark product in the industry with its innovative design concept and excellent process performance.
