Netzsch provides pre-grinding unit

Netzsch has launched its new PROPHI pre-grinding unit, which grinds coarse feed material that is 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 pace range of 8–12 m/s, a product throughput of up to 25 m³/h can be achieved with this machine size. The diameter of the grinding media used typically ranges from 2.0 – mm.
During improvement of the pre-grinding unit, a disc agitator was chosen as a outcome of the same internet power input yields virtually double the grinding chamber volume than when utilizing a pin agitator. This gives considerably more grinding physique contacts and a bigger cooling surface for grinding.
With Economical -grinding unit, the particle measurement distribution of a product may be adjusted so that very small grinding media can be used in the subsequent fine-grinding stage. Tests have shown that course of control with the Netzsch PROPHI pre-grinding unit can reduce the specific energy requirement by greater than 50% as in contrast with using basic pre-dispersion techniques.
