Netzsch provides pre-grinding unit

Netzsch has launched its new PROPHI pre-grinding unit, which grinds coarse feed materials that’s tough to deal with in a normal mill.
ไดอะแฟรม 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 speed range of 8–12 m/s, a product throughput of up to 25 m³/h may be achieved with this machine size. pressure gauge octa of the grinding media used sometimes ranges from 2.0 –4.zero mm.
During growth of the pre-grinding unit, a disc agitator was chosen as a outcome of the identical internet energy enter yields virtually double the grinding chamber quantity than when using a pin agitator. This offers considerably extra grinding body contacts and a larger cooling floor for grinding.
With a pre-grinding unit, the particle measurement distribution of a product can be adjusted in order that very small grinding media can be utilized within the subsequent fine-grinding stage. Tests have proven that process management with the Netzsch PROPHI pre-grinding unit can cut back the particular energy requirement by greater than 50% as compared with utilizing classic pre-dispersion techniques.
