ราคาเกจวัดแรงดันน้ำ has launched its new PROPHI pre-grinding unit, which grinds coarse feed materials that is troublesome to deal with in a normal 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 speed vary 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 improvement of the pre-grinding unit, a disc agitator was chosen because the identical internet power input yields virtually double the grinding chamber quantity than when utilizing a pin agitator. This provides considerably more grinding body contacts and a larger cooling floor for grinding.
With a pre-grinding unit, the particle dimension distribution of a product could 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 cut back the precise energy requirement by greater than 50% as in contrast with using basic pre-dispersion systems.
