Silica powder Flexible Screw Conveyor is suitable for conveying silica powder, a material that is prone to airflow, has poor flowability, and is susceptible to static electricity. It keeps the powder sealed and safe during transport. A single unit can convey horizontally up to 10 meters and vertically up to 6 meters; multiple units connected in series can transport even further distances. The spiral components are made of wear-resistant stainless steel, offering resistance to powder abrasion; the conveying hose is made of ultra-high molecular weight polyethylene, which is both flexible and wear-resistant. The entire system prevents dust leakage during transport and features explosion-proof and anti-static designs, reducing safety risks during transport. Hose diameters are available in 80mm, 100mm, 120mm, and 150mm, and the conveying capacity can be adjusted according to usage, ranging from approximately 0.5m³/h to 50m³/h, meeting the conveying needs of different silica powder production volumes.

The Conveying Process of a Silica Powder Flexible Screw Conveyor

The Silica powder flexible screw conveyor uses the thrust generated by the rotation of a screw to propel the powder. As the drive unit rotates the flexible screw within the enclosed hose, the screw blades slowly push the material forward along the hose wall, achieving continuous conveying. Considering the tendency of silica powder to clog, the hopper is typically designed as a vibrating hopper or a stainless steel feeder, ensuring the powder enters the conveying tube evenly and doesn't accumulate at the inlet. The screw pitch is also crucial: a smaller pitch in the feeding section helps to quickly grab and fill the material, while a standard pitch in the conveying section maintains a stable flow rate. As the screw rotates, it adapts to slight bends in the hose, using centrifugal force and friction to allow the powder to flow smoothly within the tube, preventing breakage due to excessively high flow rates or accumulation of residue due to excessively slow flow rates.

What are the Advantages of a Silica Powder Flexible Screw Conveyor?

The Silica powder flexible screw conveyor offers several advantages when conveying silica powder. The hopper features a detachable modular design, allowing for angle adjustment based on site conditions. Equipped with an anti-bridging device, it ensures smooth material feeding regardless of powder moisture content, preventing blockages. The equipment meets industrial explosion-proof requirements; the motor is explosion-proof and has passed standard certification. Operating under negative pressure reduces the risk of dust explosions and complies with safety regulations for flammable and explosive dust. For anti-static protection, the flexible hose has a conductive coating on its inner wall, and the overall grounding design effectively dissipates static electricity generated by silica powder friction, preventing sparks and accidents. The fully enclosed conveying structure prevents silica powder from scattering into the air, becoming damp, or contaminating with impurities, keeping the material clean. Cleaning and maintenance are also convenient; the simple structure allows one person to disassemble and clean it in about 10 minutes. With no additional moving parts inside the hose, no additional lubrication is needed, and it does not contaminate the silica powder. The equipment is highly compatible, working with ton bag unpackers, silos, and diversion valves to achieve integrated operation from unloading to conveying to batching.

Case Studies of Silica Powder Flexible Screw Conveyor Applications

In the power transformer manufacturing industry, a transformer factory previously relied on manual handling of silica powder, which was inefficient and generated a lot of dust. After introducing the Silica Powder Flexible Screw Conveyor, they used it in conjunction with a ton bag unpacking machine and a hopper to achieve a closed-loop conveying system for powder from ton bags to the production station. It can convey powder vertically up to 5.5 meters and vertically up to 5 meters, with a daily conveying capacity of 1.25 tons, increasing production efficiency several times over and eliminating the dust problem. In the building materials processing industry, this equipment is used in the silica powder batching and conveying process. Combined with a quantitative feeding device, it delivers quartz powder to the production line at a conveying rate of 5 m³/h, ensuring more uniform batching and avoiding errors and dust problems caused by manual operation.

The Silica Powder Flexible Screw Conveyor's structural design is tailored to the characteristics of powder, solving problems such as powder being easily scattered, generating static electricity, and being difficult to convey. The equipment is designed with sealed conveying, explosion-proof, and anti-static features in mind, making the production environment safer and reducing dust-related problems. Cleaning and maintenance are convenient; the equipment has a simple structure that allows for easy disassembly and cleaning. It can be used with ton bag unpacking machines, silos, diversion valves, and other equipment to adapt to different working conditions and industry needs. Compared to traditional conveying methods, it is more practical and allows for greater automation and smoother production. With the development of the powder processing industry, this type of equipment will be applied and improved in more fields, becoming a common choice for conveying silica powder.
