STECF Type Smooth Auto Feeder
Multi directional feeder with individually-controlled feeding system!
Features
■ Smooth Auto Feeder “STECF Type” achieved high precision feeding for various type of dry powder.
STECF consists of a agitation unit and feeder unit(s).
The Feeder unit consists of a levelling plate, closed impeller which functions as volume measuring chamber, and motor with speed reducer. Advantage of closed impeller is that material discharged in constant-volume. The impeller maintain a constant speed by speed reducer. The flow rate can adjusted by changes in rotational speed of the motor.
■ STECF can stable feeding even good flow property(i.e. fine) powder.
STECF has an outstanding material sealing performance. Since, even the material with good flow property, STECF offering stable feeding.
■ Integration system offering for various apprication.
STECF offers even integration of volumetric feeding system and pneumatic conveying system.
Structure description
【Overview】
Smooth auto feeder “STECF type” is a multi directional quantitative feeder that enables continuous feeding of powder in multiple directions (2 to 4 directions) from a single stored silo.
STECF has independent feeding units, it is possible to adjust the feeding amount individually according to the downstream equipment, so it is possible to downsizing of the equipment.
In addition, as a multidirectional feeder, by selecting the supply mechanism section that matches the properties of the powder and granular material, it is possible to select models / proposals that correspond to various facilities, such as a combination of a gravity drop method and a pneumatic conveying method .
【Structure】
The powder from the upstream equipment(e.g. silo) is relieved vertical pressure by the Spout④. Therefore, the powder is filled in the Feeding Table⑦ by Agitator⑤ with less consolidation.
The powder is leveled by the depth of the impeller of the rotating Feeding Table⑨ and is continuously discharged from the Chute⑥.
Feed rate can be adjusted by changing the motor rotation speed with the inverter.
