kraft paper produce machine for paper making industry
The kraft corrugated paper machine is a specialized equipment specifically designed for the production of kraft corrugated cardboard. Kraft corrugated cardboard, with its high strength, high toughness, excellent cushioning performance and environmental friendliness, is widely used in packaging, transportation, warehousing and other fields, especially suitable for making heavy-duty packaging boxes, pallet padding, etc. This kraft corrugated paper machine takes high efficiency, strong adhesion and low energy consumption as its core competitiveness. It integrates intelligent automation and green environmental protection concepts, providing a full-chain solution from production to recycling for the packaging industry, helping enterprises reduce costs and increase efficiency, and seize market opportunities.


The refinerof a paper machine is the core equipment in the pulp and papermaking process. It is used to grind fibrous raw materials (such as wood chips, bamboo, waste paper, etc.) into pulp that meets the requirements of papermaking through mechanical action. Its core function is to adjust the length, fineness and broomization degree of the fibers, optimize the pulp performance, and meet the production requirements of different paper varieties (such as cultural paper, packaging paper, specialty paper, etc.).
The high-concentration descaling device is an indispensable core purification equipment in the modern papermaking industry, specially designed for the impurity removal treatment of high-concentration pulp. Its core function is to effectively separate heavy impurities such as metal particles, sand and gravel, glass fragments, plastic fragments, and incompletely crushed fiber bundles from the pulp through physical centrifugal separation technology, thereby significantly improving the purity of the pulp. As a "pre-purification barrier" in the papermaking process, the high-concentration descaling device is suitable for various scenarios such as waste paper recycling, wood pulp and chemical pulp treatment, and specialty paper production. It performs particularly well in the treatment of pulp with high impurity content, such as waste paper deinking pulp and OCC (old corrugated box) pulp. This equipment adopts a tangential slurry feeding method, causing the slurry to form a high-speed vortex within the cone. Heavy impurities are thrown towards the wall of the device due to centrifugal force and eventually settle in the sediment tank, while the good slurry is discharged from the central low-pressure area. This design effectively improves the purification efficiency of the pulp and reduces the loss of fibers.
