Netzsch provides pre-grinding unit

Netzsch has released its new PROPHI pre-grinding unit, which grinds coarse feed material that’s tough to handle in a normal 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 pace vary of 8–12 m/s, a product throughput of up to 25 m³/h can be achieved with this machine dimension. The diameter of the grinding media used usually ranges from 2.0 – mm.
During ราคาpressuregauge of the pre-grinding unit, a disc agitator was chosen as a end result of the identical net power input yields virtually double the grinding chamber quantity than when using a pin agitator. This gives considerably more grinding body contacts and a bigger cooling floor for grinding.
With a pre-grinding unit, the particle size distribution of a product could be adjusted so that very small grinding media can be utilized within the subsequent fine-grinding stage. Tests have shown that course of management with the Netzsch PROPHI pre-grinding unit can scale back the particular vitality requirement by more than 50% as compared with utilizing classic pre-dispersion techniques.
