Pneumatic Vacuum Feeder

It uses vacuum negative pressure to form airflow power, so materials are conveyed in a suspended or fluidized state inside the pipeline, which is not prone to blockage and bridging. The conveying speed and flow rate can be precisely controlled by adjusting the vacuum degree and air source pressure, realizing continuous and batch material transfer with efficiency far higher than manual handling.

The whole process adopts closed pipeline conveying, so materials will not contact with the outside air. This not only avoids dust emission and pollution to the workshop environment, but also prevents materials from moisture, oxidation or impurity mixing, which is especially suitable for industries with strict hygiene requirements such as pharmaceuticals and food.

It is mainly composed of vacuum pump, suction nozzle, conveying pipeline, silo, filter and other components. With small volume and flexible layout, it can be flexibly installed according to the workshop space. It can also realize long-distance conveying in horizontal, vertical, inclined and other directions, adapting to complex production line layouts.

Without complex transmission parts, it is driven by pneumatic principle with low failure rate. Daily maintenance only requires regular cleaning of filters, inspection of seals and air source pressure, with low operation threshold and no need for professional personnel on duty. Some models are equipped with automatic unloading and cleaning functions, further reducing manual intervention.

It can convey materials in various forms, including ultra-fine powder (such as flour, medicine powder), granular materials (such as plastic particles, feed pellets), and materials with large specific gravity differences. By replacing suction nozzles and pipelines of different specifications, it can also meet the conveying requirements of materials with different particle sizes and fluidity.

Driven by compressed air, it generates no electrical sparks, making it suitable for conveying flammable, explosive and volatile materials. The equipment can be made of stainless steel, food-grade plastic and other materials to meet the requirements of special working conditions such as corrosion resistance and high temperature resistance.
