Rounding Unit GyRho
Efficient and Economical Spheroidization
Process Technology for the Rounding of Graphite
The system developed from NETZSCH overcomes all disadvantages of the standard technology and delivers an elegant solution for an efficient, processtechnology optimized graphite rounding. In a first step, the flake graphite is pre-ground to the optimum initial particle size for spheroidization in a classifier mill or fluidized bed jet mill. The actual particle rounding takes place directly downstream in the newly designed NETZSCH GyRho Rounding Unit, which is available in various construction sizes and can be specially designed to suit the necessary output quantity. For larger throughput volumes two (or more) machines can be operated simultaneously and replace a train of 40 machines or more.
The NETZSCH Process
Setting the desired product parameters is significantly simpler due to the reduced plant complexity and at the same time availability also increases.
In principle the process is divided into three phases: Filling, rounding and discharging. During the filling phase, the maximum product volume is conveyed into the processing chamber. During the rounding phase, the particles are stressed until rounded by optimum geometry and process parameters. In the discharging phase, the processing chamber is emptied by a suction unit with cyclone and separated.
