What Is Auger Filling Machinery?
Auger filling machinery is a device that uses a screw to feed powdery or small granular materials and fill them while weighing them.
Auger means “spiral apparatus” and is named so, because it uses a spiral screw.
They are sometimes called screw-type filling machines.
Auger filling machinery is incorporated into the final process of filling production.
Since the object is powdery or granular and has low fluidity, the fluidity is increased by discharging the filling through the rotation of the screw section.
At the same time, the machine enables quantitative filling of powdery fillings by measuring the prescribed amount at high speed.
Uses of Auger Filling Machinery
Auger filling machinery is used for powdery and granular materials with low dust flutter.
The auger filling machine is unsuitable for large granular materials, as the screw may crush them.

Principles of Auger Filling Machinery
Auger filling machinery uses the rotation of the screw section to discharge low-fluidity materials, thereby increasing fluidity and, simultaneously, measuring a specified amount to enable quantitative filling of powdery filling materials.
Some auger filling machines can degas filling, which suppresses dust and increases density by removing air contained in powder during screw conveyance through a degassing filter.
There are two main methods for measuring the capacity of auger filling machinery.
- Type that weighs by the number of screw revolutions. Each pitch of the screw is used as the unit capacity, and the filling degree is obtained from the number of screw revolutions.
- The type in which the contents are to be filled is weighed with a scale.
There are also products with various functions depending on the application.
- Augers that can be removed with a single touch
- Molded with a single material to prevent foreign matter from mixing in during filling
- Equipped with a degassing filling mechanism combined with a vacuum device to prevent powder leakage and falling of the filled product
- Combined with a conveyor for transport
- Combined with a feeder to enable automatic replenishment of contents
Other manufacturers have lineups that combine with peripheral equipment such as container feeders, cappers, checkers, and labelers.
