For Discharge of Powder Materials from Large Diameter Silo

Realizing stable feeding for powder and granular material required large bore outlet of storage silo.


Secures Stable Output Functionality
By integrating a volumetric feeding table with high quantitative performance, the e-Feeder ensures a higher level of stable output in comparison to traditional discharger.

Uses Less Space
The e-Feeder is compact in comparison to traditional discharger, allowing for a reduction in the amount of space used by the equipment.

Energy Efficient
This product has a smaller agitator cylinder than traditional discharger, making for a simple, saving power consumption design.
Use of the e-Feeder increases equipment-related energy efficiency.

Dual-Direction Output is Possible
As the e-Feeder is capable of continuous stable dual-direction output from a single storage silo, it helps to save space.

Capable of Being Used in Various Equipment Types
As it is possible to integrate a quantitative feeder into the dual-direction output, feeding and output corresponding to the requirements of latter-stage equipment is possible.

Capable of Feeding Many Types of Powders and Materials
Through the combination of the feeding and agitating mechanisms, the e-Feeder is capable of feeding various types of materials including those that are non-uniform in shape, as well as powders with high adhesiveness or fluidity.

EF Type
EF Type

Powders collected in the storage tank are loosened by the agitator blades (4), and in a uniform and un-compacted state are fed into the feeding table (6).

Powders fed in this manner are divided into uniform volumes by the scraper plate (8) and are then discharged into the chute (5).

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