Material pneumatic conveying system
Product Description
Introduction to Pneumatic Material Conveying System
I. Basic Principles
Using air (or an inert gas such as nitrogen) as a carrier, the material is transported from one workstation to another through a two-phase flow of gas and gas generated by a fan using negative pressure (suction) or positive pressure (pressure).
Features: Fully enclosed, leak-free, dust-free, and pollution-free.
II. Main Classifications (by Pressure)
1. Negative pressure pneumatic conveying system
- The fan draws air from the end, creating negative pressure within the duct.
- Material is drawn in through the suction nozzle, passes through a separator and dust collector, and then discharged.
- Advantages: Multi-point suction capability, low dust generation, safe operation.
- Applications: Grain and powder feeding, dust-collecting conveying in workshops, small-scale production.
2. Positive pressure pneumatic conveying system
- The blower delivers air at the front end, and the pressure inside the pipeline is higher than atmospheric pressure.
- Advantages: Long conveying distance, high output, and multi-point unloading over long distances.
- Applications: Large-scale continuous conveying, such as cement, fly ash, and chemical raw materials.
3. Dense phase/dilute phase transport (by concentration)
-
Dilute phase conveying: Low material concentration, high flow rate, suitable for light and fine powders.
Dense phase conveying: High material concentration, low flow rate, less abrasion, materials are less prone to breakage, suitable for granular and fragile materials.
III. Main Components of the System
- Air Source Equipment: Roots blower, air compressor, vacuum pump
- Feeding Devices: Rotary feeder, silo pump, screw feeder, suction nozzle
- Conveying Pipelines: Seamless steel pipe, stainless steel pipe, wear-resistant elbows
- Separation and Discharge: Cyclone separator, silo, discharge valve
- Dust Removal and Filtration: Bag filter, cartridge filter, ensuring exhaust gas meets standards
- Control System: PLC automatic control, capable of linking production line, metering, and start/stop interlocking
IV. Core Advantages
- Fully enclosed conveyor: No dust emissions, environmentally friendly and safe, meets GMP/explosion-proof requirements
- Flexible conveying route: Can turn, climb slopes, and pass through floors, without occupying ground passageways
- High degree of automation: Can be remotely controlled, continuously conveyed, and unattended
- Prevents contamination and mixing: Suitable for clean materials such as food, pharmaceuticals, and lithium battery materials
- Multi-point feeding and discharging capability, highly flexible layout
V. Applicable Materials
- Powders: Flour, starch, milk powder, cement, lime, titanium dioxide, carbon black
- Granules: Plastic particles, grains, feed, sugar, salt
- New Energy: Positive and negative electrode materials, graphite, silicon powder, lithium iron phosphate
- Chemicals: Pigments, dyes, additives, chemical powders
VI. Comparison with the IBC Transit System (Briefly)
- Pneumatic conveying: Suitable for long-distance, continuous, high-volume, fixed-route conveying.
- IBC mobile silo system: Suitable for short-distance, multi-station, flexible changeover, and low-residue transfer.
Many factories combine the two: pneumatic conveying and IBC (Integrated Circuit Baffle) buffer.
