Vacuum feeder, also known as vacuum conveyor, is a kind of dust-free and sealed
pipeline conveying equipment that uses vacuum suction to convey granular anddery
materials. It uses the pressure difference between vacuum and ambient space to
form gas flow in the pipeline, which drives the movement of powdery materials, thus
the conveying of powders.
A vacuum pump is used to produce negative pressure, which keeps the suction
nozzle inlet and the entire conveying system at a certain vacuum state, creating
pressure difference with the external environment. Under the action of the pressure
difference, powdery materials are sucked into the nozzle along with the external air,
forming a material stream, which is then transported to the hopper of the feeder
through the suction pipe. After entering the hopper, the materials are separated from
the air, and air is discharged from the system through the filter, while the materials
fall freely due to gravity. When the materials in the silo reach a certain amount or
meet the conditions, the discharge valve opens, and the materials are discharged,
and the cycle repeats.
1. Environmental protection and hygiene: The enclosed conveying method effectively
avoids dust and pollution during the conveying process, protecting the production
environment and the of workers.
2. Efficient and energy-saving: It can achieve continuous and automatic material
conveying, greatly reducing the need for manual operation and improving the overall
efficiency of the line, with relatively low energy consumption.
3. Precise control: Equipped with advanced sensors and control systems, it can monitor
the status of material conveying in real and make fine adjustments according to actual
needs, ensuring the accuracy and reliability of the conveying.
4. Strong adaptability: It can handle a variety of materials with different, shapes, and
particle sizes, such as powders and granules, meeting the production needs of different
industries and products.
5. Space-saving: The pipeline conveying occupies less space and can complete the
conveying of powdery materials in narrow spaces, making the workspace look neat and
spacious.
| Model | Hopper Capacity(L) | Working pressure | Conveying Capacity(kg/h) | Compressed air consumption |
| QVC-1 | 1.1 | 0.4-0.6Mpa | 50-300 | 180NL/min |
| QVC-2 | 6 | 0.4-0.6Mpa | 100-700 | 360NL/min |
| QVC-3 | 12 | 0.4-0.6Mpa | 300-1500 | 720NL/min |
| QVC-4 | 42 | 0.4-0.6Mpa | 600-3000 | 1440NL/min |
| QVC-5 | 60 | 0.4-0.6Mpa | 900-6000 | 2880NL/min |
Wide range of applications: The vacuum loader is mainly used for conveying
powdery and granular materials, such as raw pharmaceutical powders,
chemicalders, metal oxide powders, etc.; however, it is not suitable for conveying
overly moist, sticky, or heavy materials.
