Inclined Screw Conveyor for Stone Powder
Friday February-06 2026  16:18:15
Inclined Screw Conveyor for Stone Powder is a device used for the continuous conveying of stone powder. Stone powder particles are fine, dense, and abrasive. This screw conveyor uses rotating helical blades to push the stone powder upwards at an incline along a trough or pipe. It can meet the lifting and inclined transfer needs of stone powder in production, processing, and storage. The inclination angle of the equipment is generally between 15° and 45°, ensuring smooth upward movement of the stone powder and preventing it from sliding down or getting stuck. The lifting height can be adjusted according to site conditions, generally between 2 and 15 meters, suitable for loading materials from workshop silos or cross-section conveying on production lines. The conveying distance is usually 3-30 meters; for longer distances, multiple units can be connected in series. The conveying capacity varies depending on the model, handling 5-80 cubic meters of stone powder per hour, meeting the production needs of small workshops to large building materials plants.

Inclined Screw Conveyor for Stone Powder Design
The design of the Inclined Screw Conveyor for Stone Powder takes into account the issues of stone powder's susceptibility to wear and tear, its tendency to stick to the trough, and dust generation. The spiral blades are made of 65 manganese steel, which is highly durable and resistant to wear. Polyurethane linings are added inside the trough or pipe to prevent stone powder from sticking and to reduce dust. Heavier units use double-layered steel plates with linings for added durability. To prevent clogging, the blades feature a variable pitch design with a larger gap at the inlet and a smaller gap at the outlet, allowing the stone powder to be gradually compacted and preventing it from accumulating at the inlet. A rotating scraper or scraper edge at the tail removes stone powder adhering to the inner wall. Flanges and rubber seals are used at the inlet and outlet, and an inspection port is located at the top of the pipe to prevent dust from escaping and facilitate future maintenance.

What are the advantages of the Inclined Screw Conveyor for Stone Powder?
The Inclined Screw Conveyor for Stone Powder offers several advantages when conveying stone powder. Its design incorporates anti-clogging, anti-sticking, and wear-resistant features, resulting in virtually no residue when conveying stone powder. The flow is also relatively stable, and the fully enclosed operation minimizes dust generation and impacts the workshop environment. Low noise levels also minimize disruption to production. In terms of installation and layout, the equipment has a compact structure, requires minimal space, and does not require complex support platforms. It can be flexibly placed in corners, production line gaps, or small spaces next to silos. Installation is simple, and future disassembly or relocation is convenient, reducing costs during site modifications. Compared to belt conveyors, it eliminates concerns about belt misalignment or slippage, making it more suitable for fine powder materials like stone powder, and it offers better sealing. Compared to bucket elevators, its simple structure makes maintenance easy, reducing the likelihood of material jamming or clogging, and it can continuously and stably convey stone powder, meeting the needs of continuous production. Compared to pneumatic conveyors, it consumes less electricity, has lower operating costs, and is more adaptable to the moisture content of stone powder, allowing for smooth conveying even slightly damp powder.

Inclined Screw Conveyor for Stone Powder Models
Inclined Screw Conveyors for Stone Powder come in several common models, generally distinguished by their conveying structure or installation method. The most common types on the market are pipe-type and trough-type. Pipe-type models, such as GX219, GX273, and GX325, have numbers representing the inner diameter of the pipe. They feature a closed structure, good dust prevention, and are often used in fine stone powder processing workshops. Trough-type models, such as LS200, LS300, and LS400, have numbers representing the trough width. They are easier to clean and maintain, suitable for large-capacity sand and gravel plants or cement plant raw material silos. Based on installation method, they can also be divided into fixed and mobile types. Fixed types, such as the GXF series, are suitable for long-term fixed production lines; mobile types, such as the GXY series, are equipped with casters and supports at the bottom, allowing for flexible movement and easy repositioning in warehouses. Different models can be selected based on conveying capacity, workshop space, and usage requirements.

Inclined Screw Conveyor for Stone Powder Application Cases
The Inclined Screw Conveyor for Stone Powder has been applied in the building materials, ore, and powder processing industries, with numerous successful implementation cases. A large cement plant uses multiple GX325 tubular inclined stone powder screw conveyors to lift limestone powder from the grinding workshop to a 10-meter-high finished product silo. The equipment is inclined at 30° and can convey 60 cubic meters per hour. Its closed-loop operation solves the problems of dust pollution and material blockage associated with traditional conveying equipment. A sand and gravel plant uses the LS300 trough type, combined with a cleaning device and polyurethane lining, for the storage and transfer of machine-made stone powder. Stone powder does not easily stick to the walls, and the equipment runs continuously for 10 hours a day without problems, meeting the plant's production rhythm.

The Inclined Screw Conveyor for Stone Powder is a conveying equipment designed specifically for the characteristics of stone powder. Its parameters and structure have been specifically adjusted to solve the problems of wear, blockage, and dust generation that easily occur when conveying stone powder at an incline. During use, the conveying is stable and the efficiency remains at a good level. It is also flexible to install, relatively easy to maintain, and has low operating costs. Compared with traditional conveying equipment, it is more adaptable to stone powder, which can make the conveying links of the production line run smoothly and reduce manual intervention. Currently, this type of equipment is used in stone powder conveying in industries such as building materials and ore processing, becoming a frequently chosen option for conveying stone powder in the production chain.
