Leizhan’s Light Impurity Separator is designed as a critical pre-screening or post-pulping purification unit for both virgin and recycled pulping lines. Unlike generic screening equipment that struggles to separate low-density impurities from fiber pulp, this Light Impurity Separator leverages a combination of centrifugal separation and fluid dynamics to deliver targeted, efficient removal. Leizhan’s R&D team adjusted the flow channel geometry and inlet pressure parameters to ensure that light impurities are fully separated without trapping good fiber. Test data from dozens of operating mills shows that the machine reduces overall impurity content in pulp by 90% or more, with fiber loss controlled below 1%, far outperforming traditional coarse screening equipment.

Available in a range of processing capacities from 50 to 1,000 dry tons per day, the Light Impurity Separator can be easily integrated into new pulping lines or retrofitted into existing facilities. It works seamlessly with other Leizhan pulping equipment (including pulpers, pressure screens, and cleaners) and can be customized for specific production needs, whether producing packaging paper, cultural paper, tissue, or board. Leizhan’s Light Impurity Separator enables mills to process lower-cost, higher-contamination recycled feedstock while still producing high-quality end products, supporting circular economy goals and improving profitability.
