1 M or U type is selected depending on the powder properties.(M type：Powder U type：Powder, Granular)
2 M type only
Variable range is 1:5(12~60Hz) for M type, 1:4(15Hz~60Hz) for U type.
The feed rate is theological value as the powder bulk density at 1.0. It may vary from the above feed rate depending on powder apparent specific gravity or property etc.

Explanation

The feeder feeds a fixed quantity of powder measured on a measuring disk by cutting and_ sweeping off with a cutting disk in proportion to the volume of measures and_ the revolving speed of measuring disk. It is wide variety of capacity types in combination of the various measuring disks (M & U type) and_ reducers. The below is the sectional drawing for internal structure of body for YAF-M□ type and_ YAF-U□ type.
* Air flowrate control valve is option.
