Continuous feeding of 10 μ or less fine powder
Features
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.

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.The feeding rate range differs depending on the powder type, particle size, shape, state, optional item configuration and carrier gas conditions.
We recommend the use of Mass Flow Controller, because the gas pressure needs to be constant for stable feeding.
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.
It changes with the consumption degree of O-ring. O-rings need to be replaced regularly.
The capacity can be increased by mounting an optional hopper.
