Netzsch has launched its new PROPHI pre-grinding unit, which grinds coarse feed material that is difficult to deal with in a standard mill.
pressure gauge ไฮ ด รอ ลิ ค is a disc agitator bead mill modified for coarse grinding with high throughput and a grinding chamber volume of approx. 20 litres. In the peripheral velocity vary of 8–12 m/s, a product throughput of up to 25 m³/h may be achieved with this machine size. The diameter of the grinding media used typically ranges from 2.0 –4.zero mm.
During development of the pre-grinding unit, a disc agitator was chosen as a outcome of the identical net power input yields almost double the grinding chamber quantity than when utilizing a pin agitator. This gives considerably extra grinding physique contacts and a bigger cooling floor for grinding.
With a pre-grinding unit, the particle size 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 process management with the Netzsch PROPHI pre-grinding unit can reduce the precise vitality requirement by greater than 50% as compared with utilizing traditional pre-dispersion methods.
