CGS Jet Mill – Micron Dry Grinding Machine
Netzsch CGS 10 pilot scale (Suitable for high wear/hard to grind products)
The CGS model has high speed nozzles evenly arranged horizontally. Grinding is achieved not only at the center of air currents, but also by the speed differences between the high speed air and surrounding air. There is extremely low wear because the powder does not collide with the chamber walls, making it suitable for grinding extremely hard products (e.g. diamonds) with fineness reaching 1~2um (d50).
The feature of this machine is the patented ConVor classifier system of Netzsch and the horizontal operation method. These two features have a key effect on the range of particle size of products that complete the grinding process.
The special geometric design of the ConVor separation system allows powder to maintain the same speed when passing through the separation system. This prevents particles that are too large from being brought out of the system due to an increase in speed, and allows the narrow range of fineness unmatched by competitors to be achieved. The horizontal rotation puts powder under the same force from every angle when the separation system is operating, allowing for the particle size to be accurately controlled.
There are also laboratory and mass production models of CGS, and any results achieved on laboratory machines can be scaled-up to mass production machines.
Different grinding chamber interiors and explosion-proof designs are available. All tests on dry grinding machines are performed in the laboratory of Neztsch in Germany.
