Multi-Feed from the One Silo

Individual feed rate alignment for downward-flow equipment.


Can accurately feed a wide variety of dry powder
Our feeders scrape powders from a container and batch it by volume, which allows for high accurate, stable feeding for a wide variety of dry powders.

Allows steady feeding of highly fluid powder
With tightly sealed Encircle Disc allows stable feeding of highly fluid powder as well.

Allows combination of the pneumatic conveyance method and natural fall method
Because the pneumatic conveyance method and natural fall method can be combined into one system, a wide-range of responses depending on equipment specifications are possible.



The Smooth Auto Feeder (ST-type) is a multidirectional quantitative feeder which enables continuous powder feeding from a storage silo to multiple directions (2-4 directions).

Can be adjusted in this feeder, because the agitator unit and the various feeding units are independent, feed rate s conforming to downstream equipment and the space required for install at on can be minimized.

Additionally, because it’s a multidirectional feeder, by selecting the feed unit based on powder properties, both natural fall method and pneumatic conveyance method are possible.

With the spout (4) (powder pressure reducing device) at feeder inlet and the agitator (2), stored powder or grain materials are deposited inside the feeding table (9) with constant density and without compression.

Powders fed in this manner are divided into uniform volumes by the scraper plate and are then discharged into the chute (6).

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

Examples of Applications with ST-type Feeders



In rechargeable battery manufacturing process, our feeders are being used for feeding highly adhesive powder.
In incineration plant, our feeders are used for producing slurry blowing chemicals.
In equipment for blowing of supplementary fuels, our feeders are used as distributors to weighing machine.
