Netzsch has launched its new PROPHI pre-grinding unit, which grinds coarse feed material that is difficult to handle in a standard mill.
The PROPHI 20 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 vary of 8–12 m/s, a product throughput of as much as 25 m³/h may be achieved with this machine size. The diameter of the grinding media used typically ranges from 2.0 –4.zero mm.
During เกจวัดแรงดัน10bar of the pre-grinding unit, a disc agitator was selected as a end result of the same internet power enter yields almost double the grinding chamber quantity than when utilizing a pin agitator. This gives considerably more 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 used in the subsequent fine-grinding stage. Tests have shown that process control with the Netzsch PROPHI pre-grinding unit can reduce the precise power requirement by more than 50% as compared with using basic pre-dispersion systems.
