Netzsch has launched its new PROPHI pre-grinding unit, which grinds coarse feed materials that is difficult to handle in a regular mill.
เกจวัดแรงดันแก๊ส is a disc agitator bead mill modified for coarse grinding with excessive throughput and a grinding chamber volume 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 may be achieved with this machine dimension. The diameter of the grinding media used typically ranges from 2.zero –4.zero mm.
During improvement of the pre-grinding unit, a disc agitator was chosen because the identical web energy input yields nearly double the grinding chamber quantity than when utilizing a pin agitator. This offers considerably more grinding body contacts and a larger cooling floor for grinding.
With a pre-grinding unit, the particle measurement distribution of a product may be adjusted in order that very small grinding media can be utilized within the subsequent fine-grinding stage. Tests have proven that process control with the Netzsch PROPHI pre-grinding unit can cut back the particular power requirement by greater than 50% as compared with using classic pre-dispersion systems.
