Heavy impurity cleaners use the principle of centrifugal sedimentation to separate dense contaminants from lighter pulp fibers based on difference in specific gravity. As a professional pulping equipment manufacturer, Leizhan has refined this core pre-treatment device to meet the demands of modern high-capacity pulp lines, delivering far higher removal efficiency than traditional pre-sorting processes. Leizhan’s heavy impurity cleaner is optimized for pre-treatment and mid-stage pulp purification, with technical features tailored to long-term stable operation in harsh pulping environments.

Tangible Benefits for Paper Mill Production

1. By removing abrasive heavy impurities early, it reduces wear on refiners, screens, and pumps, cutting annual maintenance costs by 20–30% and extending the service life of high-value core equipment.
2. Early removal of hard heavy impurities eliminates defects such as paper breaks, hard spots, and surface unevenness, improving finished paper yield and product grade.
3. Automatic continuous operation reduces unplanned shutdowns for impurity cleaning and equipment repairs, improving overall line uptime and output.

For paper mills planning new pulping lines or retrofitting old equipment, a reliable heavy impurity cleaner from Leizhan is a high-return investment that supports long-term stable operation.
