Netzsch has launched its new PROPHI pre-grinding unit, which grinds coarse feed materials that’s tough to handle in a standard mill.
เกจ์วัดแรงดันน้ำมันเครื่อง 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 speed vary of 8–12 m/s, a product throughput of up to 25 m³/h may be achieved with this machine dimension. The diameter of the grinding media used sometimes ranges from 2.0 –4.0 mm.
During improvement of the pre-grinding unit, a disc agitator was chosen because the identical internet power enter yields virtually double the grinding chamber quantity than when using a pin agitator. This gives significantly more grinding body contacts and a larger cooling surface for grinding.
With a pre-grinding unit, the particle measurement distribution of a product may be adjusted so that very small grinding media can be utilized within the subsequent fine-grinding stage. Tests have proven that course of control with the Netzsch PROPHI pre-grinding unit can scale back the specific energy requirement by greater than 50% as in contrast with utilizing classic pre-dispersion techniques.
