Vacuum feeding, also known as vacuum conveyor, is a device that uses gas to generate vacuum and transport powder materials. It is a type of gas conveying. Suitable for multiple industries such as pharmaceuticals, food, chemicals, metallurgy, and building materials
Reduce dust pollution and improve working environment;
Reduce environmental and personnel pollution of materials and improve cleanliness;
Small space occupation, able to complete powder conveying in narrow spaces, making the workspace beautiful and generous, without being limited by long and short distances;
Reduce manual labor intensity and improve work efficiency;
The entire conveying process is carried out in a closed system, and there will be no powder leakage;
The equipment has no gaps or dead corners that are prone to material accumulation, and the surface is easy to visually inspect.
A vacuum feeder is a device that uses a vacuum pump to extract air, keeping the inlet of the suction nozzle and the entire system in a certain vacuum state. The powder and granular materials are sucked into the nozzle along with the external air, forming a material airflow that passes through the suction tube to reach the hopper, where gas and material are separated. The separated materials enter the receiving equipment. Conveying and discharging are achieved through the continuous opening and closing of pneumatic three-way valves, which are controlled by the control center.
The vacuum feeder is equipped with a compressed air blowback device. Each time the material is discharged, the compressed air pulse blowback the filter, knocking down the powder adsorbed on the surface of the filter, so that the suction can operate normally.

Note: The above production capacity refers to the capacity when conveying flour as the material. The conveying distance is equal to the horizontal distance plus the vertical height. If the material conveying distance is doubled, the conveying capacity will be halved. Additionally, the fluidity and characteristics of the material have a significant impact on the conveying capacity.
The vacuum feeder is suitable for multiple industries such as pharmaceuticals, food, chemicals, metallurgy, and building materials. It is designed for the closed conveying of various powder materials, improving the cleanliness of the materials and meeting the diverse conveying needs of different customers.
