Flexible Screw Conveyor for Abrasive Sand plays a crucial role in conveying bulk fine and coarse sand, particularly abrasive sand materials. Thanks to its unique flexible design, this conveyor can transport materials horizontally, inclined, or vertically, with a maximum conveying distance of up to 30 meters. It can seamlessly connect to silos, mixing plants, and truck loading systems, achieving seamless integration of the process flow. In standard configuration, its conveying capacity is consistently between 5 and 20 tons per hour. Whether used for molding sand conveying in foundries or aggregate batching in concrete mixing plants, it provides an efficient and reliable conveying solution.
The entire conveying process of the Flexible Screw Conveyor for Abrasive Sand takes place in a closed pipeline, completely eliminating the leakage of abrasive dust. The flexibility of the Flexible Screw Conveyor allows for horizontal, inclined, and even vertical conveying, and it can bypass equipment or other obstacles. The screw can be quickly withdrawn from the conveying pipe for thorough cleaning, preventing cross-contamination between different batches of materials.
The core of the Flexible Screw Conveyor for Abrasive Sand is a flexible helical spring that rotates at high speed within a sealed, flexible conveying pipe, propelling the material forward. Its flexibility means it can bend as needed, bypassing obstacles, and achieving non-linear conveying from the feed point to the discharge point.
The Flexible Screw Conveyor for Abrasive Sand offers particularly outstanding flexibility in power configuration when conveying abrasive materials such as silica sand and quartz sand. In addition to standard electric motor drive, the equipment can be equipped with a diesel engine as a power source. This feature makes it suitable for outdoor operations far from the power grid, such as remote construction sites, temporary work sites, or open-pit mines. Diesel engine drive ensures continuous and stable conveying operation even without external power, effectively overcoming site power limitations. The system incorporates multiple wear-resistant designs: the screw is made of high-carbon manganese steel and undergoes special heat treatment; the conveying pipe is lined with wear-resistant engineering plastics; and key connection points are reinforced and sealed. The conveying system can achieve horizontal, inclined, and vertical conveying, seamlessly integrating with crushing and screening equipment, mobile silos, and transport vehicles, providing a complete and efficient solution for the loading, unloading, transfer, and batching processes of outdoor silica sand and quartz sand.
Flexible screw conveyors, with their enclosed, flexible, and easy-to-clean characteristics, are one of the ideal solutions for handling abrasive sand materials. By specifically using high-wear-resistant materials for the screw and conveying pipe, and through proper selection and maintenance, they can effectively address abrasion challenges in industries such as casting, building materials, chemicals, and metallurgy.
