Material conveying equipment

Turn off the fan discharger

Introduction:

Traditional shut-off fan dischargers often cause material blockages and poor sealing due to unreasonable structures, leading to air leaks, which not only increase maintenance costs but also directly affect the continuous operation of the production line. The Head Powder Integrated Air Shut-off Unloader optimizes the clearance between the rotor and housing, addressing jamming and leakage issues at the source, making the unloading process more stable and reliable.

Traditional shut-off fan dischargers often cause material blockages and poor sealing due to unreasonable structures, leading to air leaks, which not only increase maintenance costs but also directly affect the continuous operation of the production line. The Head Powder Integrated Air Shut-off Unloader optimizes the clearance between the rotor and housing, addressing jamming and leakage issues at the source, making the unloading process more stable and reliable.

Product description

The Head Powder Integrated Air Shut-off Unloader uses a whole casting or welding process, highly integrating the motor, reducer, and discharge main body, resulting in a compact structure and easy installation. Suitable for quantitative discharge of powdered and granular materials and air locking in pneumatic conveying systems. Customizable for different materials (carbon steel/stainless steel) and special requirements for corrosion resistance and explosion protection, meeting the working conditions of industries such as food, chemical, and building materials.

Product features

  • Integrated design: The motor is directly connected to the reducer, eliminating belt transmission losses, resulting in high transmission efficiency and smooth operation.
  • Wear-resistant sealing structure: The rotor end face and housing use wear-resistant liners, combined with adjustable sealing fillings to maintain good sealing performance over the long term.
  • Anti-jam design: The rotor blades use a circular transition for smooth material flow, reducing wall snagging and blockage.
  • Easy maintenance: The bearing is external, with a well-arranged oil filling hole and observation window, so daily inspection and maintenance do not require disassembling the main body.
  • Flexible customization: rotor shape, speed, and chamber volume can be adjusted according to material characteristics, supporting non-standard interfaces and flanges.

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.
