Netzsch has launched its new PROPHI pre-grinding unit, which grinds coarse feed material that is tough to deal with 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 pace range 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 typically ranges from 2.0 –4.0 mm.
During development of the pre-grinding unit, a disc agitator was selected because the same internet energy input yields nearly double the grinding chamber quantity than when utilizing a pin agitator. This gives considerably extra grinding body contacts and a larger cooling floor for grinding.
With เกจวัดแรงดันpressuregauge -grinding unit, the particle measurement distribution of a product can be adjusted in order that very small grinding media can be used within the subsequent fine-grinding stage. Tests have proven that course of control with the Netzsch PROPHI pre-grinding unit can cut back the precise vitality requirement by more than 50% as in contrast with utilizing basic pre-dispersion systems.
