Netzsch offers pre-grinding unit

Netzsch has launched its new PROPHI pre-grinding unit, which grinds coarse feed materials that’s difficult to deal with in a regular mill.
The PROPHI 20 is a disc agitator bead mill modified for coarse grinding with excessive throughput and a grinding chamber volume of approx. 20 litres. In the peripheral velocity range of 8–12 m/s, a product throughput of up to 25 m³/h may be achieved with this machine size. The diameter of the grinding media used usually ranges from 2.0 – mm.
During เกจวัดแรงดัน of the pre-grinding unit, a disc agitator was selected as a end result of the identical internet energy input yields almost double the grinding chamber volume than when utilizing a pin agitator. This offers considerably more grinding physique contacts and a bigger cooling surface for grinding.
With a pre-grinding unit, the particle measurement distribution of a product may be adjusted in order that very small grinding media can be used within the subsequent fine-grinding stage. Tests have proven that process management with the Netzsch PROPHI pre-grinding unit can cut back the precise power requirement by greater than 50% as in contrast with using classic pre-dispersion techniques.
