Pneumatic powder conveying system

Combined positive and negative pressure pneumatic conveying

Introduction:

During powder material conveying, a single positive or negative pressure system often struggles to meet the demands of high concentration, long distance, and low energy consumption—materials are prone to clogging, energy consumption is high, and adaptability is insufficient. The Head powder positive-negative pressure combined pneumatic conveying system integrates positive pressure dense phase and negative pressure dilute phase technologies, intelligently switching based on material characteris

During powder material conveying, a single positive or negative pressure system often struggles to meet the demands of high concentration, long distance, and low energy consumption—materials are prone to clogging, energy consumption is high, and adaptability is insufficient. The Head powder positive-negative pressure combined pneumatic conveying system integrates positive pressure dense phase and negative pressure dilute phase technologies, intelligently switching based on material characteristics and process requirements to achieve efficient, stable, and low-loss conveying, fundamentally solving conveying challenges under complex working conditions.

Product description

The combined positive and negative pressure pneumatic conveying system is a flexible conveying solution designed for powdered and granular materials. The system integrates two power modes: positive pressure push and negative pressure suction, flexibly handling scenarios such as high-concentration dense phase conveying, multi-point unloading, and fragile material protection. Featuring a modular structure that supports customized configuration, it is suitable for industries such as chemicals, building materials, food, and new energy, helping users reduce operation and maintenance costs and improve production line efficiency.

Product features

  • Free switching between positive and negative pressure: automatically matches better conveying modes based on material characteristics, balancing efficiency and energy consumption.

  • Fully enclosed pipeline design: Eliminates dust leakage, meeting environmental protection and clean production requirements.

  • Intelligent control system: integrates PLC and touchscreen, real-time monitoring of pressure, flow, and material level, supporting remote operation.

  • Low energy consumption operation: Through precise air volume adjustment and pipeline optimization, it saves over 15% energy compared to traditional systems.

  • Wear-resistant and corrosion-resistant materials: pipes and key components use alloy steel or ceramic linings to extend equipment lifespan.

Product prices

The positive and negative pressure combined pneumatic conveying system is a non-standard customized device, and its price should be evaluated comprehensively based on factors such as conveying distance, material type, conveying volume, and on-site working conditions. Head Powder provides free technical consultation and preliminary design solutions, with quotations based on actual needs. Feel free to contact us for targeted quotes.

Frequently Asked Questions about Model Selection

The most frequently asked questions before placing an order. If you can't find the answer, you can leave a message or consult online.

Material name and characteristics (particle size, bulk density, moisture content, whether fragile, worn, and moisture-absorbent), conveying volume, conveying distance (horizontal/vertical), number of start and end points, and whether there are explosion-proof or cleanliness requirements on site. The more complete the information, the closer the quote is to the final version.
Yes, you can. The company has established a comprehensive pneumatic conveying testing center, supporting preliminary testing of materials and issuing measured data (air consumption, wind speed, wear, and crushing rate), which then determines the model and system configuration.
Transmission equipment and pipeline fittings are self-produced, with self-developed automation control cabinets. Solution design, manufacturing, electrical control, installation, and commissioning are all integrated, with no subcontracting and a clear responsibility interface.
