Pneumatic conveying equipment

Turn off the fan

Introduction:

In pneumatic conveying and dust removal systems, if the shut-off fan (rotary shut-off fan) has poor sealing, material jamming, or frequent maintenance, it will directly affect the efficiency and cost of the entire production line. The shut-off fans produced by Head Powder use fine processing and mature techniques to help users reduce failure rates, improve conveying stability, and make system operation more worry-free.

Product description

The Head powder fan shut-off machine, also known as a rotary air shut-off device, is a device suitable for uniformly feeding and sealing air of powdered and granular materials. Featuring wear-resistant rotors and multiple sealing structures, it maintains good airtightness under both negative and positive pressure conditions, widely used in grain, chemical, building materials, environmental protection, and other industries.

Product features

  • Reliable sealing: Uses an adjustable sealing structure combined with wear-resistant materials to reduce air leakage and wear.

  • Smooth operation: The rotor is dynamically balanced and calibrated, combined with high-precision bearings, resulting in low noise and minimal vibration.

  • Strong applicability: Offers multiple inlet and outlet flanges, transmission types, and discharge port types to suit different working conditions.

  • Easy maintenance: The split housing design makes disassembly and maintenance easy, reducing downtime.

Customized quotations

The shutdown fan is a customized product, with prices evaluated comprehensively based on material characteristics, processing capacity, working pressure, material, and non-standard dimensions. Please provide process parameters, and we will provide you with targeted solutions and accurate quotations.

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.
