Netzsch offers pre-grinding unit

Netzsch has released its new PROPHI pre-grinding unit, which grinds coarse feed materials that is tough to handle in a standard 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 speed range of 8–12 m/s, a product throughput of as much as 25 m³/h may be achieved with this machine measurement. The diameter of the grinding media used typically ranges from –4.0 mm.
During improvement of the pre-grinding unit, a disc agitator was chosen because the identical net power enter yields nearly double the grinding chamber quantity than when utilizing a pin agitator. This provides significantly extra grinding physique contacts and a larger cooling surface for grinding.
With หลักการทํางานของpressuregauge -grinding unit, the particle size 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 shown that course of control with the Netzsch PROPHI pre-grinding unit can scale back the precise energy requirement by more than 50% as compared with utilizing traditional pre-dispersion systems.
