Silica Sand Flexible Screw  conveyor can handle both dry and wet silica sand. Diameters typically range from 25mm to 200mm, with common standard models including φ57mm, φ89mm, and φ114mm. Lengths generally do not exceed 15 meters, with conveying capacities ranging from several tons to tens of tons per hour.

For fine-grained silica sand with a particle size less than 0.5mm, stainless steel or food-grade plastic should be used. For medium-grained silica sand with a particle size between 0.5-2mm, stainless steel should be used. For coarse-grained silica sand with a particle size greater than 2mm, high-wear-resistant alloy steel should be used to reduce wear on the equipment.

What are the benefits of a silica sand flexible screw?

The Silica Sand Flexible Screw is designed to handle the granular, fluid, and potentially fine dusty nature of silica sand, preventing blockages and residue during conveying, reducing material loss and equipment cleaning difficulties. The flexible spiral structure allows for flexible bending and tilting, eliminating the need for complex piping modifications. It adapts to narrow and irregular workshop spaces and reduces layout constraints. The spiral blades fit snugly within the conveying pipe, ensuring uniform sand transport and preventing material accumulation or uneven flow rates, ensuring continuous production and improving overall efficiency. The Silica Sand Flexible Screw features a relatively simple structure with few wearing parts, making daily inspection and replacement easy and reducing maintenance downtime. Its sealed design minimizes dust emission, equipment wear, and environmental cleanup costs.

Silica Sand Flexible Screw Selection

Selecting a Silica Sand Flexible Screw should be based on the characteristics of the silica sand. For ultra-fine silica sand (<0.2mm), dust prevention is crucial; for coarse silica sand (>2mm), wear resistance and anti-jamming are key.

Silica Sand Flexible Screw Options for Ultra-Fine Silica Sand <0.2mm

The equipment can be configured with a 304 stainless steel blade and a PU hose. Care should be taken to prevent wear and seal the equipment to reduce dust. The conveying capacity is 5-15 m³/h to avoid sand accumulation and clogging. A pipe diameter of 50-80 mm increases thrust and reduces residue.

Silica Sand Flexible Screw Options for Fine Silica Sand 0.2mm-0.5mm

The equipment can be configured with a 304 stainless steel blade and a PVC hose, offering moderate cost and corrosion resistance. The conveying capacity is 10-25 m³/h, balancing efficiency and clogging prevention. A pipe diameter of 80-120 mm reduces friction and protects the equipment.

Silica Sand Flexible Screw Options for Medium-Grained Silica Sand 0.5mm-1mm

Select a 316 stainless steel blade and a wear-resistant rubber hose for enhanced wear and corrosion resistance. The conveying capacity is 20-40 m³/h, suitable for good flowability. A pipe diameter of 120-160 mm reduces conveying pressure and is suitable for large-scale production.

Silica Sand Flexible Screw Options for 1mm-2mm Coarse Silica Sand

High-chromium alloy blades and ultra-wear-resistant polyurethane hoses provide resistance to abrasion from hard particles. The conveying capacity is 15-35m³/h, preventing blade overload. The pipe diameter is 160-200mm to reduce sand squeeze and protect equipment.

Silica Sand Flexible Screw Options for Large Silica Sand (>2mm)

For large silica sand particles larger than 2mm, choose a bimetallic composite blade (carbon steel + tungsten carbide) and wear-resistant ceramic hose to resist severe wear. The conveying capacity is 10-25m³/h, preventing impact and jamming at low speeds. The pipe diameter is 200-250mm to ensure smooth particle flow.

Silica Sand Flexible Screw Applicable Materials

In addition to silica sand, the Silica Sand Flexible Screw can also convey granular materials such as quartz sand, glass sand, resin pellets, plastic pellets, grains, beans, fertilizer pellets, and feed pellets. For powdered materials, it can handle cement powder, lime powder, talc powder, flour, milk powder, graphite powder, carbon black, pigment powder, and laundry detergent powder. It can also convey some small, non-sharp materials, such as small coal particles, slag particles, clay pellets, and small pieces of candy or chopped nuts used in the food industry.

About Silica Sand

Silica sand is a sand-like mineral primarily composed of quartz and is low in impurities. It can be used in glassmaking, building concrete, metal casting, and other applications. It can also be treated to remove harmful substances and used as play sand. Ordinary sand has a complex composition, containing impurities such as clay and feldspar, and is of low purity. Silica sand, on the other hand, has a high quartz content, high purity, and more stable performance.

The Silica Sand Flexible Screw can be handheld or combined with a truck for easy mobility. Different materials or pipe diameters can be selected for conveying silica sand according to the particle size and moisture content of the sand. Its flexible spiral structure and flexibility make it an excellent tool for conveying silica sand.
