The auger filling machine is a high-precision, efficient and versatile machine for quantitative filling of free-flowing or non-free-flowing granular materials and powder products into containers, pouches or bags. The flour packing machine https://www.zenofilling.com/product/flour-packing-machine/ reference applies the working principle of the auger, keeping the pitch of the spiral blades the same, thus ensuring that each spiral pitch is filled with materials of the same volume and particle size. The material is conveyed forward by rotation, and the predetermined amount of product is accurately and consistently dispensed.

1. Optimize auger design
- Choose the right auger type: Different auger designs are suitable for different materials. Choose the right auger design (such as single screw, double screw) according to the material characteristics (such as fluidity, particle size, viscosity).
- Adjust pitch and diameter: Pitch and diameter affect the material conveying volume and accuracy
- Reduce auger wear: Check the auger wear regularly and replace the seriously worn auger in time.

2. Accurately ...
... control the auger speed
- Use high-precision motor: Abandon the traditional clutch brake system and equip with servo motor to accurately control the auger rotation speed and number of turns.
- Optimize speed parameters: Adjust the auger speed according to the material characteristics and filling volume, and continuously optimize the screw speed that best suits the material

3. Improve metering method
- Volumetric metering: Measuring materials by controlling the number of auger rotations or time, suitable for materials with good fluidity.

- Weighing metering: Use high-precision weighing sensors during the filling process, stop filling after reaching the target weight, suitable for materials with high precision requirements.

4. Optimize material flow
- Improve material properties: Ensure that the material is dry and uniform, and avoid caking or sticking.
- Use agitator: Install an agitator in the hopper to prevent material clogging.
- Vibration assistance: Install a vibrator in the hopper or screw to promote material flow.

Site preparation: Ensure that the surface where the machine is placed is level and stable.

Machine positioning: Place the machine in the designated area, install the anchor bolts, and fix the equipment. Ensure stability without shaking. And leave enough space for operation and maintenance.

Power and gas source connection（Motor and Drive System）: Connect the power cord according to the power requirements (such as 220V or 380V). Gas source requirements (usually 0.5-0.7 MPa), connect the gas source pipeline.

Hopper loading: Load the expected product into the hopper through the vacuum feeder and ensure smooth flow without material leakage.

Filling head and container positioning device: a. Filling head: Adjust the height and position of the filling head according to the container size; b. Ensure that the container is aligned with the filling head, and install the container positioning device (such as a bottle clamp or positioning plate).

Calibration and testing:

- No-load operation:

Start the equipment without material filling and check whether each component is operating normally.

Check whether the auger rotation, filling head and conveyor belt are running smoothly.

- Load operation:

After adding the material, conduct a trial run to check whether the filling accuracy and speed meet the preset parameter requirements. Adjust the auger speed, filling speed and container positioning device to ensure the filling volume is accurate.

Final operation: Based on the above tests, make improvements to ensure the filling volume is accurate. After repeating 2-3 times without error, the machine is installed.
