Netzsch has launched its new PROPHI pre-grinding unit, which grinds coarse feed material that is tough to handle in a standard mill.
The PROPHI 20 is a disc agitator bead mill modified for coarse grinding with excessive 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 much as 25 m³/h could be achieved with this machine measurement. The diameter of the grinding media used usually ranges from 2.zero –4.zero mm.
During improvement of the pre-grinding unit, a disc agitator was selected as a result of the identical net energy enter yields nearly double the grinding chamber quantity than when utilizing a pin agitator. This offers considerably more grinding body contacts and a bigger cooling floor for grinding.
With a pre-grinding unit, the particle size distribution of a product can be adjusted in order that very small grinding media can be utilized in the subsequent fine-grinding stage. pressure gauge ไท วัสดุ have proven that course of management with the Netzsch PROPHI pre-grinding unit can cut back the precise energy requirement by more than 50% as compared with using classic pre-dispersion methods.
