EF Type Discharge Feeder

For Discharge of Powder Materials from Large Diameter Silo
Features
■ Secures Stable Output Functionality
Secures Stable Output Functionality
■ Space saving design!
In comparison with the conventional mass flow discharger, because the body diameter is compact, it enables space-saving. Discharger “e-Feeder” is possible to use a small motor because it can reduce the vessel diameter by using an impeller shaped discharge table. This means there is an advantage that your facility can be simplified.
■ 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.
■ Two-way discharge is possible with custom design.
Since it can discharge in two directions with one e-Feeder, it can be discharged from one silo to two different downstream processes.
■ e-Feeder offering hybrid multi task feeding system.
It can be customized to e-Feeder which integrates not only mere discharge but also volumetric quantitative supply system.
■ Customizable for various materials
By combining various agitation units and feeder units, e-Feeder can discharge various kinds of powders and materials such as amorphous raw material, adhesion, powder with high fluidity, etc.

Structure description
【Structure】
The powder from the upstream equipment (e.g. Silo) is charged to the Feeding Table⑥ in a uniform condition without consolidation by the Agitator④.
The raw material charged to the Feeding Table⑥ is levelled to a certain amount by the Levelling Plate⑧ and discharge from the Chute⑤ section.
EF achieves a variable feed rate by the inverter adjustment.
