Powder feeding station Working Process

aterial processing industries, transferring bagged materials to the next production stage requires a reliable and dust-free system. The Bag Discharging Station is designed to streamline this process by integrating bag opening, feeding, dust collection, and material screening into a single unit.

During operation, bags are manually opened and placed into the Bag Discharging Station, where materials are emptied efficiently. The dust-laden air, generated during the dumping process, is captured by an induced draft fan and directed into the dust removal system. Inside the system, air moves opposite to the airflow, allowing the high-efficiency filter element to trap fine dust particles. This prevents airborne dust contamination and ensures that only purified air is discharged through the outlet of the induced draft fan, maintaining a clean working environment.

To further enhance processing efficiency, the Bag Discharging Station is equipped with a vibrating sieve at its bottom. This sieve helps to remove oversized particles, foreign objects, or bulk materials, ensuring that only uniform and qualified particles proceed to the next stage. For seamless material transfer, a vacuum feeder can be integrated, allowing the screened material to move efficiently to the next process step without dust dispersion.

This advanced system is particularly suitable for handling materials with poor fluidity, preventing loss and contamination while optimizing workflow efficiency. By combining dust-free feeding, precise screening, and automated conveying, the Bag Discharging Station enhances operational safety, reduces manual labor, and improves overall productivity in various industries.

How Does a Dust-free Feeding Station Work?

The working principle of a dust free system involves the following steps:

Step 1: Material Feeding

The material to be screened is fed into the center of the sieve through an inlet.

Step 2: Gyratory Motion

The motor generates vibrations, which cause the sieve to vibrate in a gyratory motion. This motion spreads the material evenly across the screen surface.

Step 3: Particle Separation

As the material moves across the screen, particles smaller than the sieve openings pass through, while larger particles are retained on the screen surface.

Step 4: Discharge

The separated particles are discharged through designated outlets, while the oversized particles continue to travel towards the outlet end of the sieve. Small granules are directly transported to the designated equipment, such as the packaging machine hopper or the powder mixer, using a vacuum feeder under negative pressure.
