Durable Reject Separator machine for Efficient Paper Making Processes
Reject Separator is a key equipment in paper machinery used for the efficient separation of pulp impurities such as sand grains, metal shavings and fiber clusters. It is made of 304/316L stainless steel or wear-resistant alloy and has a processing capacity of 10-500 m³/h. Working pressure: 0.2-0.6MPa, suitable power: 5.5-75kW. Its centrifugal or screening technology can achieve an impurity separation efficiency of ≥95%, and it is equipped with an automatic slag discharge valve or a screw conveyor system, supporting continuous slag discharge (adjustable frequency: 5-60 times per minute). The products are divided into centrifugal type (high-precision sand removal) and pressure screen type (coarse residue filtration), with single-stage or multi-stage configurations. The core advantages include modular design, IP54 protection level, low energy consumption (energy saving 15%-20%) and PLC intelligent control (compatible with DCS system), and comply with ISO 15361 standard. It is widely applied in pulp purification, waste paper recycling and special paper production lines, and is compatible with equipment of brands such as Andritz.
The upflow pressure screen is a highly efficient and energy-saving pulp screening equipment, widely used in the fields of waste paper pulping, pulp screening before paper machines and recycled pulp treatment. Its core advantage lies in achieving efficient impurity removal and fiber grading through a unique upflow structure and pressure difference screening principle, significantly enhancing the quality of the slurry and production efficiency.
The pulp pump of paper making machinery is a core equipment in the paper making industry used for transporting pulp, white water, additives and other media, directly affecting production efficiency and paper quality. Its design needs to take into account wear resistance, corrosion resistance, high efficiency and low energy consumption to adapt to the complex working conditions of high temperature, high humidity and high solid content in the paper making process.
