Pneumatic Conveyor Price Stainless Steel Dust Free System

Pneumatic Conveyor Product Introduction

Pneumatic conveyor, also known as vacuum conveying system or vacuum loader, is an advanced dust-free material handling solution. It uses a vacuum pump to generate negative pressure airflow inside a closed pipeline system.

Materials such as powders and granules are automatically sucked into the system through suction nozzles, transported through pipelines, and separated in a filtration chamber. Clean air is released while materials are discharged into target equipment such as mixers, hoppers or storage tanks.

With automatic control and compressed air reverse pulse cleaning, the system ensures continuous stable operation and high conveying efficiency.

Working principle

Step 1: Vacuum pump generates negative pressure (-0.3 to -0.6 bar)
Step 2: Airflow creates suction inside closed pipeline
Step 3: Material is sucked into inlet nozzle through pressure difference
Step 4: Powder/granules travel through conveying pipe
Step 5: Mixture enters filter separation chamber
Step 6: Air is separated and filtered from material
Step 7: Clean air is discharged from system
Step 8: Material is collected in hopper or discharge unit
Step 9: Compressed air pulse cleans filter automatically
Step 10: System repeats cycle for continuous feeding
