Flexible Screw Conveyor For Dry Sand
Tuesday March-03 2026 10:10:08
Flexible Screw Conveyor For Dry Sand is adapted to the abrasion and flow characteristics of dry sand in terms of materials, structure, and accessories. The outer casing is typically made of thickened, wear-resistant PU tubing, stainless steel tubing, or corrosion-resistant carbon steel tubing, offering both toughness and wear resistance. The spiral blades are mostly made of high-manganese steel, 304 stainless steel, or wear-resistant carbon steel, capable of withstanding the erosion of dry sand, making them less prone to deformation and breakage, and extending their service life.
Its conveying capacity varies with pipe diameter and rotational speed, ranging from 2 to 30 tons per hour, suitable for both small-scale site transfers and large-scale production line supply. Common pipe diameters include Φ76mm, Φ102mm, Φ114mm, and Φ160mm, but custom sizes are also available based on production volume and site conditions. Connections are typically made using quick-install flanges, clamps, or threaded connections for easy assembly and disassembly. It is also equipped with hoppers, vibratory feeders, motor reducers, control boxes, and sealing joints to reduce dust and material leakage. When using, align the inlet with the sand source and place the outlet in the designated position. After powering on, the screw rotates, moving the sand. The flow rate can be adjusted using a frequency converter. Start the machine under no-load conditions and stop the material flow before powering off, allowing the sand to be discharged completely. Operation is relatively simple.
What are the installation methods for the Flexible Screw Conveyor for Dry Sand?
The Flexible Screw Conveyor for Dry Sand offers flexible installation options, adaptable to construction sites and workshops. For horizontal installation, simply place it on the ground or erect a simple support frame; suitable for short-distance horizontal feeding, such as transfers between two hoppers. Inclined installation angles are generally between 0° and 45°, allowing feeding from low to high levels, commonly used for dry sand conveying. Vertical lifting installation allows for direct upward feeding, saving considerable floor space. Curved installation utilizes the flexibility of the hose to bypass machines, walls, or pillars, making it suitable for confined spaces. The mobile installation, equipped with casters or a trolley, allows it to move with the construction site, making it suitable for temporary material transfers and loading on construction sites. Installation only requires securing the motor end and a few support points; no complex civil engineering is needed, and one person can quickly set it up and adjust it.
What are the advantages of using a Flexible Screw Conveyor for Dry Sand?
The Flexible Screw Conveyor for Dry Sand is flexible, movable, and can even be used at an angle, accommodating even the most complex site conditions. It uses a fully enclosed pipeline conveyor, keeping dry sand flowing inside and preventing dust from escaping, resulting in a cleaner working environment. The blades and pipes are made of wear-resistant materials, making it durable and reliable even with repeated use. The simple structure, without intermediate bearings, prevents sand from getting stuck and requires minimal maintenance. Compared to belt conveyors and pneumatic conveyors, it is cheaper to buy and uses less electricity, making it more cost-effective in the long run. The conveying process is consistently smooth with a uniform sand flow; when connected to automated equipment, it provides stable material supply without constant human monitoring.

In which scenarios is the Flexible Screw Conveyor for Dry Sand suitable?
The Flexible Screw Conveyor for Dry Sand can be used in many aspects of production. For example, in building material factories processing manufactured sand, dried sand, and quartz sand, it can be used directly from the production line to the packaging stage; on construction sites, it can supply sand to mortar mixing plants, facilitate sand transport to upper floors, backfilling of foundation pits, temporary dumping, and loading. In sand and gravel yards, it can also be used for transfer between silos, retrieval from the stockpile, and loading onto trucks. In industries such as refractory materials, glass, and casting, it is suitable for dry sand batching, feeding, and production line conveying. In ports and warehouses, it can easily handle unloading, warehousing, and outbound transport of dry sand. It is convenient and quick to use in small mixing plants, precast concrete plants, and other places that require a continuous supply of dry sand.
