Netzsch provides pre-grinding unit

Netzsch has launched its new PROPHI pre-grinding unit, which grinds coarse feed material that’s difficult to handle in a standard 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 velocity range of 8–12 m/s, a product throughput of up to 25 m³/h can be achieved with this machine measurement. The diameter of the grinding media used typically ranges from 2.0 –4.0 mm.
During เกจวัดแรงดันเชื้อเพลิง of the pre-grinding unit, a disc agitator was selected as a end result of the identical net power input yields nearly double the grinding chamber quantity than when using a pin agitator. This offers significantly extra grinding physique contacts and a larger cooling surface for grinding.
With a pre-grinding unit, the particle size 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 shown that process control with the Netzsch PROPHI pre-grinding unit can cut back the specific power requirement by greater than 50% as compared with using classic pre-dispersion systems.
