The High Density Cleaner is a specialized purification device installed typically after pulpers or detrashing equipment. Operating at consistencies ranging from 2% to 5%, it utilizes centrifugal force to separate heavy impurities—such as stones, staples, glass, sand, and other dense debris—from the fiber suspension before the stock advances to screening, refining, and the paper machine approach system. The High Density Cleaner focuses on coarse, high-specific-gravity contaminants, making it indispensable for protecting valuable downstream equipment like refiners, pressure screens, and headbox components from abrasive wear and catastrophic damage.

Our High Density Cleaners feature high-alumina ceramic cones that offer exceptional resistance to abrasion. This significantly extends service life, even when handling abrasive contaminants, and maintains consistent separation efficiency over time. The main body and piping are fabricated from high-grade stainless steel, ensuring corrosion resistance, structural integrity, and long-term durability in demanding mill environments. Available in single-cone, double-cone, or multi-cone arrangements, Leizhan High Density Cleaners can be tailored to match your specific capacity requirements, from small packaging mills to large-scale pulp production lines.
