Features

TP-99140FDR Fine Powder Feeder

Continuous feeding of 10 μ 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.
