Netzsch provides pre-grinding unit

เกจวัดแรงดันน้ำประปาราคา has released its new PROPHI pre-grinding unit, which grinds coarse feed material that is troublesome 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 volume of approx. 20 litres. In the peripheral pace range 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 –4.0 mm.
During pressure gauge วัด แรง ดัน น้ำ of the pre-grinding unit, a disc agitator was selected as a end result of the same web power input yields virtually double the grinding chamber quantity than when using a pin agitator. This gives significantly extra grinding body contacts and a larger cooling surface 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 used in the subsequent fine-grinding stage. Tests have proven that process management with the Netzsch PROPHI pre-grinding unit can reduce the specific energy requirement by more than 50% as in contrast with using basic pre-dispersion systems.
