Netzsch has released its new PROPHI pre-grinding unit, which grinds coarse feed materials that’s troublesome to deal with in a regular mill.
The PROPHI 20 is a disc agitator bead mill modified for coarse grinding with high throughput and a grinding chamber quantity of approx. 20 litres. In the peripheral pace vary of 8–12 m/s, a product throughput of as much as 25 m³/h can be achieved with this machine measurement. The diameter of the grinding media used sometimes ranges from 2.zero –4.0 mm.
During development of the pre-grinding unit, a disc agitator was selected because the same web energy enter yields virtually double the grinding chamber quantity than when using a pin agitator. This provides considerably extra grinding physique contacts and a bigger cooling surface for grinding.
With compound gauge ราคา -grinding unit, the particle dimension distribution of a product could be adjusted so 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 specific power requirement by more than 50% as compared with using traditional pre-dispersion systems.
