Extractor systems – HSF type
The “HSF” type of silos may be used for several kinds of wooden material such as wet chips, wet and/or dry flakes, wet and/or dry particles and dust. It is a sliding frame extractor which consists of a sturdy elliptical frame sliding back and forth on the bottom of a round silo, the frame is operated through one or two hydraulic pistons, located outside of the silo and driven by a hydraulic unit.
The back-and-forth movement of the frame conveys the material into the opening located on the bottom of the silo; from here it is discharged into one or more metering screws to feed the conveyors arranged downstream.
Extraction and handling systems play a primary role in a production plant.
Their proper function will ensure a regular material flow, thus enhancing efficiency and availability of the whole plant.
Extraction systems for discharge of material from storage silos are available in different versions to meet any specific requirements and needs.
Advantages
Possibility of installing several metering screws on the bottom of the silo
