Netzsch has launched its new PROPHI pre-grinding unit, which grinds coarse feed materials that’s troublesome 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 quantity of approx. 20 litres. In the peripheral pace vary of 8–12 m/s, a product throughput of up to 25 m³/h may be achieved with this machine measurement. The diameter of the grinding media used typically ranges from 2.zero –4.zero mm.
During development of the pre-grinding unit, a disc agitator was chosen because the identical internet power input yields almost double the grinding chamber quantity than when utilizing a pin agitator. This provides considerably more grinding body contacts and a bigger cooling surface for grinding.
With เครื่องวัดแรงดันเกจที่นิยมใช้ -grinding unit, the particle size 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 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 techniques.
