The function of the disc is to accelerate the grinding media centrifugally from the outer edge and centripetally from the inner edge of the disc creating shearing forces between the disc and the media. This agitation is carried to the surrounding media radially and axially by the kinetic energy imparted to the media by the disc.
TriNE Disc System.
NETZSCH offers three types of disc agitation systems:
- TriNEx™ (tri-lobe) Discs
- MoliNEx™ (eccentric) Discs
- Concentric Discs
The TriNEx™ (tri-lobe) Disc System is the most poplar NETZSCH design. When the shaft is rotated, these discs pulse the grinding media at a high frequency against the product flow. This results in an even distribution of the grinding media in the chamber.
TriNEx Discs
NETZSCH disc mills are primarily used for processing low to medium viscosity (1 to 200 poise) formulations. Solids levels in paint applications have been as high as 85% for industrial and furniture paints and ceramic slurries or slips
