SF-Type continuous metal spirals

Continuous metal spirals, or screw conveyors, are key components in various industries. These devices, designed for the efficient transport of materials, are essential to ensure smooth and uninterrupted operations.

SF-Type metal augers represent one of the most advanced and versatile solutions available. Below we will review the main features, advantages and applications of SF-Type continuous metal augers. 

Characteristics of SF-Type continuous metal spirals

SF-Type metal augers are manufactured using high-quality materials such as carbon steel and 304/316 stainless steel. These materials guarantee durability and strength, making the spirals suitable for a wide range of operating conditions.

Used materials:

  • Stainless steel 304/316: stainless steel is chosen for applications where corrosion resistance is crucial, such as in the food, chemical and pharmaceutical industries. 316 steel, in particular, offers greater corrosion resistance than 304.
  • Carbon steel: this material is ideal for applications requiring strength and durability. Carbon steel is cost-effective and performs well in non-corrosive environments.

Size and specifications

SF-Type spirals are only available in standard sizes, ensuring a ready-to-use product without the need for customisation. The available sizes are as follows:

  • Outer diameter (Ø D): 40 to 100 mm
  • Pitch (P): Constant or variable
  • Inside diameter (Ø d): 20 to 60 mm
  • Thickness (Spp): 3 to 8 mm

These specifications allow the spirals to be adapted to a wide range of applications, providing flexibility and versatility in use.

Use with or without central tube

SF-Type spirals can be used with or without a central tube, offering further options to meet the specific needs of each application. This feature is important to ensure the correct movement of materials, depending on the configuration of the conveying system.

Right (RH) or left (LH) pitch

SF-Type spirals are available with pitch to the right (RH) or left (LH), offering further options to suit operational needs. The ability to choose the pitch direction is crucial to ensure efficient transport of materials.

Advantages of SF-type helical metal spirals

SF-Type metal spirals offer numerous advantages over other material handling solutions. Some of the main advantages include:

  1. Transport efficiency: thanks to their helical design, the spirals ensure continuous and uniform transport of materials, minimising waste and blockages.
  2. Versatility: different material options, sizes and pitches make SF-Type spirals suitable for many industries, from food processing to chemical and mining industries.
  3. Durability and reliability: the choice of high quality materials and precision manufacturing ensure long life and constant reliability.
  4. Easy maintenance: the spirals are designed for easy installation and maintenance, reducing downtime and operating costs.
  5. Flexibility in use: the possibility of using the spirals with or without a central tube offers greater flexibility in applications, allowing them to adapt to different system configurations.

Applications of SF-Type continuous metal spirals

SF-Type continuous metal spirals find applications in numerous industrial sectors due to their efficiency and versatility. Below are some of the main applications:

food industry - SF-Type continuous metal spirals

Food industry

In the food industry, helical spirals are used to transport raw materials such as flour, sugar and other ingredients. The use of stainless steel ensures compliance with hygiene standards and corrosion resistance, which is essential in environments where cleanliness is paramount.

chemical industry - SF-Type continuous metal spirals

Chemical industry

Spirals are used to convey powders and granular materials, ensuring a continuous flow and preventing contamination of materials. 316 stainless steel is particularly valued for its resistance to aggressive chemicals, ensuring a long service life.

mining industry - SF-Type continuous metal spirals

Mining industry

In the mineral industry, SF-Type continuous metal spirals are essential for transporting heavy and abrasive materials such as ore and sand. The carbon steel provides the strength to cope with harsh operating conditions, extending the life of the equipment.

pharmaceutical industry - SF-Type continuous metal spirals

Pharmaceutical industry

Continuous stainless steel spirals are used to transport powders and chemical compounds in the production of pharmaceuticals. Corrosion resistance and ease of cleaning are crucial in this sector, ensuring compliance with quality and safety standards.

waste management - SF-Type continuous metal spirals

Waste management

SF-Type spirals are also used in waste management systems for the transport of solid and semi-solid materials. Their robustness and reliability make them ideal for this type of application, ensuring continuous operation and minimising downtime.
