Netzsch offers pre-grinding unit

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 speed range of 8–12 m/s, a product throughput of up to 25 m³/h can be achieved with this machine size. The diameter of the grinding media used typically ranges from 2.0 –4.0 mm.Get more news about pin bead mill,you can vist our website!

During development of the pre-grinding unit, a disc agitator was selected because the same net power input yields almost double the grinding chamber volume than when using a pin agitator. This gives significantly more grinding body contacts and a larger cooling surface for grinding.

With a pre-grinding unit, the particle size distribution of a product can be adjusted so that very small grinding media can be used in the subsequent fine-grinding stage. Tests have shown that process control with the Netzsch PROPHI pre-grinding unit can reduce the specific energy requirement by more than 50% as compared with using classic pre-dispersion systems.
The NEMO BO/SO progressing cavity pump has a hopper and a coupling rod with feeding screw and force-feed chamber, which also houses the cutting unit. The pump can be used in many industries but primarily within food processing, where continuous, pressure-stable, gentle and low-pulsation conveyance of cut media is required.

The attached hopper ensures an efficient supply of the medium to the conveying elements. By passing the cutting unit in the feeding chamber larger pieces of the medium are cut immediately. The cutting unit contains a rotating knife fixed on the coupling rod, which is equipped with three blades and a variable number of stationary knives. The number of knives can be adapted to the size and consistency of the particles.
