The densifier model HV is a system to densify flakes and regrind of low bulk density - e.g. shavings, film, fibers and foam - with. The agglomerate has a higher bulk density than the original flakes, it has good flow characteristics and can be extruded or injection-molded without forced feeding. In mixing silos (e.g. after film washing systems) densified material gives higher amounts of material in a mixing batch, thus producing a more equal mixture, compared to material not densified.

Compared to standard batch type agglomerators the HV densifier is a continuous process without adding water to the material. The flakes are being granulated and automatically fed into the agglomerator via a buffer silo. The densified material is being reground in a second granulator; an air classifier sorts out dust and fine particles and returns them again into the densification process for further agglomeration.
The agglomerator itself consists of two discs equipped with kneater pads. One of the discs is rotating with high speed; a drive power between 22 kW and 160 kW (30 HP to 220 HP) on the rotating disc generates the friction needed for the densification process.
