For Wet and Cake Powders

Allows the stable feed of powders difficult to feed and expel.

Features
  • By increasing the entrance diameter, stable feed is possible without bridging.
  • Because it is possible to select the model based on the requirements of powder properties, this type can also be used for dry powder.

RD Type Details
Outline
Makes the Feeding of Highly Adhesive Wet Powders Possible

Through the combined use of the special-configuration ring feeding table and the scraper no revolving on the feeding table occurs, making stable feeding of highly-adhesive wet powders possible.

Make-up
Retained powder are separated by the agitator (4) and in a non-compacted state are filled from the spout aperture (5) to the feeding table (7).

Filled powder are moved to the chute (6), where the scraper (7) forcibly cuts the powder into the chute (6).

Adjustment of the feed rate is performed through variations in the rotation speed through spout adjustments (5) and the inverter.

RE Type Details
Outline
Makes Possible the Stable Feeding of Powders Difficult to Expel and Feed

The combination of the scraper plate aperture being set to the characteristics of the powders and the ring-type feeding table makes possible the stable feeding of difficult powders from dry powders to fibrous and spongy materials.

Make-up
Retained powder are separated by the agitator (5) and in a non-compacted state are filled from the scraper plate (4) to the feeding table (7).

Filled powder are cut to a fixed volume and are continuously feed to the chute (6).

Adjustment of the feed rate is performed by varying rotation speed at the inverter.

RS Type Details
Outline
Makes Possible the Expulsion and Feeding of Irregularly Shaped Raw Materials and Cake Powders

Through the combined use of the ring-type feeding table and scraper, the expulsion and feeding of hard-to-expel irregularly shaped raw materials and cake powders is possible.

Anti-Compacting Function Makes Possible the Stable Feeding of Irregularly Shaped Materials

Performing forward-reverse alternating operation through timed operation or the load torque screening function protects against compaction of the raw materials and allows stable feeding.
(For feeding raw materials such as factory refuse)

Make-up
Retained powder are separated by the agitator (5) and in a non-compacted state are filled to the feeding table (7) through the scraper plate (4).

Filled powder are cut to a fixed volume, where the scraper (8) forcibly cuts the powder into the chute (6).

Adjustment of the feed rate is performed by varying rotation speed at the inverter.
