Valmet’s hydrocyclone technology removes unwanted particles such as sand, glass, metal, inks, certain unwanted organics, plastics, wax, and Styrofoam down to 50 microns. The result is cleaner pulp, better quality products, and the protection of process equipment downstream.

Low consistency hydrocyclones

Low consistency cleaning involves removal of fine debris such as sand, ink, specks of bark, wax or bits of Styrofoam. The typical low density hydrocyclone operates at 1% consistency and is available in different configurations depending on the specific gravity of the unwanted particles.

Medium consistency hydrocyclones

Valmet offers medium consistency hydrocyclone technology that is designed to optimize efficiency. Typical medium consistency cleaning applications involve sand removal at approximately 2% consistency.

High Consistency Cleaners

Valmet offers high consistency cleaning solutions that meet requirements for various pulps with applications for both single-stage and two-stage systems.
