Netzsch offers pre-grinding unit

Netzsch has launched its new PROPHI pre-grinding unit, which grinds coarse feed material that’s tough to deal with in a normal mill.
เกจอาร์กอน 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 up to 25 m³/h could be achieved with this machine dimension. The diameter of the grinding media used typically ranges from 2.zero –4.zero mm.
During growth of the pre-grinding unit, a disc agitator was chosen because the same internet energy input yields almost double the grinding chamber quantity than when utilizing a pin agitator. This gives considerably more grinding body contacts and a bigger cooling surface for grinding.
With a pre-grinding unit, the particle size distribution of a product may be adjusted so that very small grinding media can be used within the subsequent fine-grinding stage. Tests have shown that process management with the Netzsch PROPHI pre-grinding unit can reduce the particular vitality requirement by more than 50% as compared with using classic pre-dispersion methods.
