Netzsch offers pre-grinding unit

Netzsch has launched its new PROPHI pre-grinding unit, which grinds coarse feed material that is difficult to handle in a normal mill.
The PROPHI 20 is a disc agitator bead mill modified for coarse grinding with high throughput and a grinding chamber volume of approx. 20 litres. In the peripheral velocity range of 8–12 m/s, a product throughput of as a lot as 25 m³/h could be achieved with this machine size. The diameter of the grinding media used sometimes ranges from – mm.
During เครื่องมือที่ใช้วัดความดันโลหิต of the pre-grinding unit, a disc agitator was chosen as a result of the identical net power input yields almost double the grinding chamber quantity than when utilizing a pin agitator. This offers considerably extra grinding physique contacts and a bigger cooling surface for grinding.
With a pre-grinding unit, the particle measurement distribution of a product can be adjusted so that very small grinding media can be utilized in the subsequent fine-grinding stage. Tests have shown that course of management with the Netzsch PROPHI pre-grinding unit can reduce the precise power requirement by more than 50% as compared with using basic pre-dispersion techniques.
