Continuous feeding of 10 μm or less fine powder
- Continuous quantitative feed of under a few micron particles with highly cohesive and poor fluidity.※
- Powder feeding rate is around 0.1 to 100 g/min or more by changing option items.※
- Because of the closed structure, it is possible to feed into reduced-pressure atmosphere. (e.g. 100 Pa)
- Can monitor and record the real-time powder feeding rate and the total feed amount. (Option)
- Not only single powder but also mixed powder can be fed continuously without changing mixing ratio.
※ The feeding condition differs according to the powder type, size, shape, weight and state.

- ※1: The range of powder particle size that can be fed differs depending on the type, shape and state of the powder.
We have experienced 200 to 300 μm powder.
- ※2: The feeding rate range differs depending on the powder type, particle size, shape, state, optional item configuration and carrier gas conditions.
- ※3: We recommend the use of Mass Flow Controller, because the gas pressure needs to be constant for stable feeding.
- ※4: Depending on the tube diameter and length, 20 L/min may not be supplied. If the gas flow is too low, powder may not be fed.
- ※5: It changes with the consumption degree of O-ring. O-rings need to be replaced regularly.
- ※6: The capacity can be increased by mounting an optional hopper.
