A screw conveyor is a device specifically designed for conveying and unloading powdery and granular materials,
used in conjunction with a baghouse dust collector.
It is primarily installed at the bottom of the dust collector hopper for the continuous conveying and unloading of collected dust.

This equipment utilizes rotating screw blades to propel material at a uniform speed, achieving automated centralized unloading, feeding, and loading/unloading/conveyance of dust. It completely solves problems such as low efficiency of manual dust removal, dust generation during unloading, and ash blockage. It is a core supporting device in dust collection systems for achieving automated ash conveying, continuous operation, and dust-free unloading, and is widely compatible with large and medium-sized baghouse dust collectors.

For dry dust, fine particulate matter, and small fragments collected by dust collectors, it has a stable, continuous, and uniform conveying capacity. It can achieve real-time emptying of ash from the hopper, preventing dust accumulation, bridging, and blockage, ensuring stable negative pressure in the dust collector hopper, and not affecting the overall dust collection airflow and filtration efficiency.
The machine adopts an integrated tubular/trough structure, ensuring strong airtightness and preventing dust spillage and secondary dust generation. The conveying process is clean and environmentally friendly, meeting the requirements of cleanroom operations and effectively improving the factory production environment.
The spiral blades are made of thickened wear-resistant material, with strong welding, high conveying thrust, wear resistance, and anti-jamming properties. They can withstand continuous feeding for extended periods, are not easily deformed or broken, and are suitable for long-term operation in high-load, dusty industrial environments.
Equipped with an industrial standard geared motor, it features high transmission torque, stable operation, low noise, and low energy consumption. It enables uniform speed variable frequency speed control for feeding, supports controllable start/stop and quantitative conveying, and is suitable for unattended operation in automated dust removal production lines.
The simple and compact structure, without complex transmission components, results in a low failure rate. It exhibits excellent anti-clogging and anti-jamming performance, ensuring stable and reliable overall operation, making it suitable for long-term continuous industrial operations.
Widely compatible with large and medium-sized pulse bag dust collectors, high-temperature bag dust collectors, and ash hopper conveying in industrial powder recovery equipment. Suitable for various dry dust conveying applications in mining, cement, building materials, metallurgy, chemical, grain processing, woodworking dust removal, power plant dust removal, and other industries. It can be connected to silos, carts, and elevators for centralized dust collection and transfer.
The equipment comes standard with a complete screw shaft, wear-resistant blades, a geared drive motor, sealed end caps, and inlet/outlet components. Accessories are comprehensive and highly versatile. The machine body adopts a closed structure, preventing dust and clogging, and minimizing material accumulation, simplifying daily maintenance. It supports various structures including tubular and trough types, and can be customized with different pipe diameters and lengths. The appropriate model can be matched to the dust collector's ash hopper volume, dust specific gravity, and conveying distance, and is compatible with both new and old dust collectors for installation and upgrades.
The screw conveyor is designed for automated continuous ash conveying and dust-free, closed discharge, suitable for dust collection applications with large dust volumes requiring continuous ash removal. For small-volume, single-unit dust collection applications, it can be used with a discharge valve for intermittent ash discharge, allowing for flexible configuration based on ash production to maximize the automation level of the dust collection system.
