Netzsch presents pre-grinding unit

Netzsch has launched its new PROPHI pre-grinding unit, which grinds coarse feed materials that is troublesome to deal with in a normal mill.
เกจวัดแรงดันปั๊มลมpuma 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 speed vary of 8–12 m/s, a product throughput of as a lot as 25 m³/h could be achieved with this machine dimension. The diameter of the grinding media used usually ranges from –4.0 mm.
During improvement of the pre-grinding unit, a disc agitator was selected as a outcome of the same internet power enter yields virtually double the grinding chamber quantity than when using a pin agitator. This provides significantly more grinding physique contacts and a larger cooling floor for grinding.
With a pre-grinding unit, the particle size distribution of a product can be adjusted so that very small grinding media can be utilized within the subsequent fine-grinding stage. Tests have proven that course of control with the Netzsch PROPHI pre-grinding unit can scale back the particular power requirement by more than 50% as compared with using basic pre-dispersion systems.
