Stainless Steel Inclined Screw Conveyor

What is Stainless Steel Inclined Screw Conveyor?

The main function of Stainless Steel Inclined Screw Conveyor  is to lift powdery, granular or small block materials from a lower position to a higher position. This type of equipment can be roughly divided into small inclination (0° to 20°), medium inclination (20° to 45°) and large inclination (45° to 90°) types according to its inclination angle to adapt to different material lifting needs and site restrictions. In terms of material handling capacity, Stainless Steel Inclined Screw Conveyor can handle materials from several cubic meters to tens of cubic meters per hour, and the conveying distance of a single device usually ranges from several meters to more than 20 meters.

What are the types of Stainless Steel Inclined Screw Conveyor?

Stainless Steel Inclined Screw Conveyor is a conveying equipment widely used in food, chemical and other industries. Its core feature is that the conveying path is inclined, and stainless steel is used to meet hygiene or corrosion protection requirements. According to the inclination angle, it can be roughly divided into the following types:

Inclination angle range: usually refers to the inclination angle between 0° and 20°.

Design features: In this angle range, the material can maintain good fluidity and filling rate under the push of the spiral blade, similar to horizontal conveying, but with a certain lifting capacity. Usually no special anti-backflow structure is required, or only simple adjustment is required.

Applicable materials: Suitable for most powdery and granular materials with good fluidity, such as grains, flour, small granular plastics, dry powders, etc.

Inclination angle range: usually refers to the inclination angle between 20° and 45°.

Design features: In this angle range, the tendency of material to reflux under the action of gravity begins to become obvious. In order to ensure effective conveying, measures may need to be taken, such as increasing the spiral speed, increasing the filling rate of the spiral blade, or using a variable pitch design to compensate for the influence of gravity. For some materials that are prone to slipping, special spiral blade forms may be required.

Applicable materials: It is still applicable to most powdery and granular materials, but the viscosity and fluidity requirements of the materials are slightly higher.

Inclination angle range: usually refers to the inclination angle between 45° and 90° (vertical).

Design features: In this angle range, the influence of gravity on the material is very large, and the efficiency of traditional screw conveying will be greatly reduced. Therefore, this type of conveyor usually requires special design, such as a fast-rotating closed screw. Driven by the high-speed rotating screw, the material is thrown to the pipe wall by centrifugal force and pushed up by the spiral blades, similar to the working principle of a centrifugal pump. Special spiral blades may use non-standard pitch, widened blades or special shapes to better grasp and lift materials. Higher drive power, overcoming gravity to do work, requires greater motor power.

Applicable materials: It is suitable for powdery or small granular materials with good fluidity and not easy to agglomerate, and has certain requirements for the friction coefficient and viscosity of the material.

What are the advantages of Stainless Steel Inclined Screw Conveyor?

With its unique structure and material selection, Stainless Steel Inclined Screw Conveyor has shown many advantages in material transportation, especially suitable for scenarios with specific requirements for hygiene, corrosion protection and material lifting.

Excellent hygiene and corrosion resistance: This is the core advantage of Stainless Steel Inclined Screw Conveyor. All parts in contact with the material are made of food-grade stainless steel (such as 304 or 316L). This material has excellent corrosion resistance and can resist the erosion of various corrosive media such as acids, alkalis, and salts, ensuring the stable operation of the equipment in a humid and highly corrosive environment. At the same time, the surface of stainless steel is smooth, not easy to absorb materials, easy to clean and disinfect, and can effectively prevent material contamination and bacterial growth.

Realize material height difference transportation: The inclined design enables it to lift materials from a lower position to a higher position, effectively utilizing space. Whether feeding from a ground hopper to a high-level mixing tank or lifting materials to a packaging machine or storage bin, the Stainless Steel Inclined Screw Conveyor can complete the vertical height transfer within a limited footprint, simplify the process flow, and reduce the need for additional lifting equipment.

Strong airtightness: Compared with ordinary conveying equipment, the Stainless Steel Inclined Screw Conveyor usually adopts a fully enclosed tubular or covered trough structure. This design effectively prevents material leakage and dust flying during transportation, and improves the cleanliness of the working environment. At the same time, it also protects the material from contamination by the external environment, which is especially important for powder or granular materials with high requirements for purity.

Stable operation and continuous conveying: The screw conveyor can provide a continuous and smooth material flow to ensure a smooth production process. Despite the inclined conveying, through reasonable pitch, speed and blade design, the equipment can effectively overcome the influence of gravity, prevent material backflow or slippage, and ensure stable lifting and conveying of materials.

Wide adaptability and convenient maintenance: Stainless Steel Inclined Screw Conveyor is suitable for conveying a variety of powdered, granular, and small block materials. The spiral blade form (such as variable pitch, paddle blade) and speed can be adjusted according to different material characteristics. In addition, many stainless steel screw conveyors are also designed with quick-open or easy-to-disassemble structures to facilitate internal inspection, cleaning, and maintenance, thereby extending the service life of the equipment and reducing operating costs.

What are the applications of Stainless Steel Inclined Screw Conveyor?

Stainless Steel Inclined Screw Conveyor is widely used in various industrial and production scenarios. Its core function is to safely, hygienically and continuously lift various types of powdered, granular or small block materials from low to high.

Material height difference transfer: It can effectively transport materials from a lower collection point, hopper or ground to a higher mixing equipment, reactor, dryer, packaging machine feed or storage silo. This lifting capacity allows the material handling process to be arranged vertically, saving horizontal space.

Process flow connection: In multi-stage production lines, Stainless Steel Inclined Screw Conveyor is often used to connect processing units at different heights. For example, after the material is initially processed (such as mixing and screening), it needs to be lifted to the next processing link (such as filling, tableting, drying). It can provide a continuous and controlled material flow to ensure the smooth connection of the production process.

Material conveying in controlled environments: Due to the use of stainless steel and the usually closed design, this type of conveyor is suitable for occasions with strict requirements on environmental cleanliness, material purity or corrosion protection. It can prevent the material from being contaminated by the outside during the conveying process, or prevent the material itself from corroding the conveying equipment, ensuring the hygiene of the production environment and the long-term operation of the equipment.

Metering and precise feeding assistance: Stainless Steel Inclined Screw Conveyor can be used in conjunction with weighing equipment or metering systems to achieve accurate and quantitative lifting and feeding of materials. This is particularly important in processes that require feeding high-level containers according to specific recipes, ensuring the accuracy and consistency of production.

Occasions with high requirements for cleaning and maintenance convenience: Considering the easy cleaning and disinfection characteristics of stainless steel, this type of conveyor is particularly suitable for production lines that require frequent material changes and thorough cleaning to prevent cross contamination.
