The Low Density Cleaner operates on the principle of centrifugal separation at relatively low pulp-consistency (low density), typically handling diluted pulp suspensions. Feed slurry enters a rotor/stator or conical chamber where centrifugal forces and controlled flow patterns separate low-density contaminants (stickies, plastics, films, lightweight rejects) from the heavier fiber fraction. Rotational speeds and internal geometry are optimized to minimize shear and fiber attrition, preserving fiber strength and quality—important for deinked pulp and long-fiber grades.

 

Advantages of Low Density Cleaner

1. Reduces specks, holes, and defects caused by light contaminants, improving sheet appearance and runnability.
2. Low fiber carryover into rejects ensures more of the valuable fiber remains in the cleaned furnish.
3. Less contamination sent to refiners, washers, and paper machines translates to fewer breaks, lower nozzle and felt fouling, and less need for rework.
4. Can be adjusted for variable furnish types and contamination loads, supporting mills that process varied recycled inputs.
5. Low energy consumption, reduced maintenance needs, and high uptime contribute to lower total operating cost.
