Netzsch has launched 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 can be achieved with this machine dimension. The diameter of the grinding media used sometimes ranges from 2.zero –4.0 mm.
During development of the pre-grinding unit, a disc agitator was selected because the identical internet energy enter yields nearly double the grinding chamber volume than when using a pin agitator. pressure gauge 4 นิ้ว ราคา offers significantly extra grinding physique contacts and a larger cooling floor for grinding.
With เกจวัดแรงดันpsi -grinding unit, the particle dimension 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 course of control with the Netzsch PROPHI pre-grinding unit can scale back the specific power requirement by greater than 50% as in contrast with utilizing traditional pre-dispersion methods.
