Shaftless Screw Conveyors

Shaftless screw conveyors are designed for applications where the material is sticky or difficult to handle. They are ideal for transporting sludge, screenings, and other materials that tend to stick to the screw. Shaftless screw conveyors are available in various sizes and can handle a wide range of materials.

Vertical Screw Conveyors

Vertical screw conveyors are used to transport materials vertically. They are ideal for applications where space is limited, and the material needs to be moved vertically. Vertical screw conveyors are available in various sizes and can handle a wide range of materials, including powders, granules, and flakes.

In summary, there are several types of screw conveyors designed for specific applications. Horizontal screw conveyors are the most common type, while inclined, shaftless, and vertical screw conveyors are used for specific applications.

Components and Design

Screw Flights

The screw flights are the essential components of a screw conveyor. They are responsible for conveying the material through the conveyor. The flights are made of various materials, such as carbon steel, stainless steel, and hardened steel, depending on the application. The size and shape of the flights are also critical in determining the conveyor’s capacity and efficiency. The screw flights can be either helicoid or sectional, depending on the application.

Troughs and Housings

The trough and housing of a screw conveyor are responsible for containing the material being conveyed. The trough can be either U-shaped or tubular, depending on the application. The housing can be either open or closed, depending on the material being conveyed. The trough and housing are typically made of carbon steel, stainless steel, or galvanized steel, depending on the application.

Drive Units

The drive unit of a screw conveyor is responsible for providing the necessary power to operate the conveyor. The drive unit can be either electric or hydraulic, depending on the application. The motor size and horsepower are critical in determining the conveyor’s capacity and efficiency. The drive unit can be either mounted on the conveyor or remotely located, depending on the application.

Feed and Discharge Points

The feed and discharge points of a screw conveyor are responsible for loading and unloading the material being conveyed. The feed point can be either a hopper or a chute, depending on the application. The discharge point can be either a spout or a valve, depending on the material being conveyed. The feed and discharge points can be either located at the same end or opposite ends of the conveyor, depending on the application.

In summary, the components and design of a screw conveyor are critical in determining its capacity, efficiency, and overall performance. The screw flights, troughs and housings, drive units, and feed and discharge points are the essential components of a screw conveyor that must be carefully designed and selected to meet the specific needs of each application.

Materials and Build Quality

Screw conveyor manufacturers offer a variety of materials and build qualities to meet the specific needs of their customers. Here are some of the most common options:

Stainless Steel Conveyors

Stainless steel is a popular choice for screw conveyor construction due to its durability, corrosion resistance, and cleanability. It is often used in food and pharmaceutical applications where hygiene is critical. Manufacturers may offer different grades of stainless steel, with 304 and 316 being the most common.

Carbon Steel Conveyors

Carbon steel is a cost-effective option for screw conveyor construction. It is strong and durable, making it suitable for a wide range of applications. However, it is not as corrosion-resistant as stainless steel, so it may not be the best choice for applications where the conveyor will be exposed to moisture or corrosive materials.

Abrasion-Resistant Alloys

For applications where the conveyor will be handling abrasive materials, manufacturers may offer conveyors made from abrasion-resistant alloys. These alloys are designed to withstand the wear and tear of abrasive materials, such as sand, gravel, or minerals. Common abrasion-resistant alloys include AR400 and AR500.

Overall, the choice of material and build quality will depend on the specific needs of the application. Manufacturers should work closely with their customers to understand their requirements and recommend the best options for their needs.

Applications and Industries

Screw conveyors are used in a wide range of industries for various applications. Some of the common industries that use screw conveyors include agriculture, food processing, pharmaceuticals, and construction.
