Types of Screw Conveyor:
As screw conveyor manufacturers in India, here are some detailed types of our provided conveyors.
- Horizontal Flexible Screw Conveyor: This type of screw conveyor is widely used in large-scale industries such as manufacturing units and big plants due to its popularity. It is designed to transport dry bulk materials effortlessly to any location.
- Vertical Screw Conveyors: Vertical screw conveyors are structured to lift materials vertically. They are primarily utilized in situations that involve the movement of large amounts of materials between various levels without the need for additional lifting equipment. The vertical position assists in organizing substances such as powders, grains, and liquids in predetermined patterns.
- Fly Ash Screw Conveyor: This conveyor is ideal for transporting or supplying materials like cement or fly ash. It includes components such as screws or flights, U-trough, drive systems, inlet/outlet, bearings, and seals. An electric motor powers the screws in a fly ash screw conveyor, typically made of mild steel. Fly ash or cement enters through the inlet and exits through the outlet at the other end. This type of conveyor is commonly found in thermal power plants, cement or brick production, chemical industries, etc.
- Double Screw Conveyor: It has two parallel helical screws that rotate to transfer bulk materials from one level to another in controlled flow. These screws are connected to an electric motor for its rotating operation. This conveyor includes screw shafts, troughs, inlet/outlet, and drive system as its components. It is utilized in a range of sectors, including chemical, food, agriculture, healthcare, cement, mining, etc.

Key Components of Screw Conveyor:
Screw conveyor suppliers in India offer high-quality systems designed with key components as follows:
- Helical Screw (Flighting): The helix—the rotating screw or flighting through which material moves on a conveyor. Often made of durable materials such as stainless steel or hardened plastic, the screw has precise dimensions for pitch, diameter, and shape to suit various applications.
- Casing (the tube or trough): It is a compartment that consists of the rotating screw and prevents spilling material. Being made of sturdy steel means that it is suitable for safe material transportation, and because its flaps are easy to access, all the maintenance tasks required can also be carried out easily.
- Drive Mechanism: The motor or gearbox powers the screw, controlling both speed and directional changes for different bulk handling needs. Energy-efficient drives enhance operational life.
- Inlet: Material enters the conveyor from hoppers or feeders, allowing smooth flow with potential flow control to prevent blockages and ensure steady feeding.
- Output: The output section works in coordination with other equipment for efficient storage. Material flow can be controlled in increments through adjustable outlets.
Benefits of Screw Conveyor:
We, at screw conveyor suppliers in India, supply a wide range of conveyors with the following benefits:
- Large Quantity Materials Handling:Due to its double screw structure, it can handle large amounts of materials. These substances consist of semi-solids, sludge, bio-solids, and wet or dry products. The screw conveyor has several discharge points for distributing bulk materials.
- Tailored Choices: Our conveyors come in various sizes and configurations to meet diverse customer needs. They feature different types of screws with various diameters, pitch variations, and designs to suit specific requirements.
- Less Noise Level: The screw conveyor can operate in silent mode as compared to other systems. Many industries, such as food and plastics, are located near residential areas. For this industrial process, our offered conveyors are the perfect choice and help other residential people to tolerate any kind of noise.
- Quick Installation: It has compact-sized and flexible components that make it easy to install quickly and also maintain simplicity.
Features of Screw Conveyor:
- Efficient Material Handling: Smooth bulk material transport without clogging, good solution for low-maintenance applications
- Versatility: Can be used in multiple industries and has the capability to manage wet, dry, or abrasive materials.
- Space Efficiency: Compact design allows for fitting into tight spaces with both horizontal, vertical, or inclined configurations.
- Durable and Reliable:They are made of robust materials, ensuring long-term use even in extreme weather.
- Cost-Effective: A low-power bulk-movement solution that minimizes operational costs while maintaining reliable movement processing.
