Kraft corrugated testliner paper making machinery Mechanical Pulp Refiner
The refiner of a paper machine is the core equipment in the pulp and paper making process. It is used to grind fibrous raw materials (such as wood chips, bamboo, waste paper, etc.) into pulp that meets the requirements of paper making 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.).In terms of technical features, the grinding discs of the double-disc grinding machine are made of high-chromium cast iron, which has high hardness and strong wear resistance. The tooth profile of the grinding disc can be selected as either the dissolving type or the fine grinding type according to the type of slurry. The clearance adjustment system adopts a three-level adjustment architecture, including coarse adjustment of worm gear and worm, medium adjustment of hydraulic/electric, and fine adjustment of PLC, which can achieve clearance control at the 0.01mm level. In terms of power configuration, the main shaft speed can reach 1800r/min, and it is equipped with spline floating connection and drum gear coupling to ensure the stability of high-speed operation.
