Netzsch has released its new PROPHI pre-grinding unit, which grinds coarse feed material that’s troublesome to deal with 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 velocity range of 8–12 m/s, a product throughput of as a lot as 25 m³/h may be achieved with this machine measurement. The diameter of the grinding media used typically ranges from 2.zero –4.0 mm.
During growth of the pre-grinding unit, a disc agitator was selected because the same internet energy input yields virtually double the grinding chamber quantity than when utilizing a pin agitator. This offers significantly more grinding body contacts and a bigger cooling floor for grinding.
With เกจวัดแรงดันไฟฟ้า -grinding unit, the particle measurement distribution of a product could be adjusted so that very small grinding media can be used in the subsequent fine-grinding stage. Tests have shown that course of management with the Netzsch PROPHI pre-grinding unit can scale back the particular energy requirement by greater than 50% as compared with utilizing traditional pre-dispersion methods.
