Types of Screw Feeders:
Serving as the screw feeder manufacturers in India, our products are available in different types, such as:
- Automatic Screw Feeder: It is among the most commonly utilized varieties of screw conveyor or feeder. It has components such as screw shafts, flights, housing, inlets/outlets, bearings, hoppers, and drive mechanisms used in its construction. Its pitch can fluctuate throughout the screw lengths, adjusting the flow rate as needed. The optimal choice for accurate control is a variable-pitch feeder.
- Mass Flow Screw Feeder: This feeder has one, two, or multiple screws to ensure consistent material discharge. This feeder is ideal for controlling flow with accuracy. It is equipped with a motor controlled by a variable frequency drive (VFD) that allows for speed adjustments. A mass flow feeder is used to control materials like fine materials or granular materials, which flow easily.
- Inclined Screw Feeder: Inclined screw feeders with U-troughs are commonly used for inclines up to 15 degrees, while tubular housings are preferred for slopes exceeding 15 degrees. Decreasing the screw's pitch enhances the efficiency factor of the incline by offering a superior conveying surface and preventing bulk materials from falling back, in contrast to full-pitch flights.
- Live Bottom Screw Feeder: This type of screw feeder in India contains multiple screws that work together to produce a “live bottom.” The hopper's materials are removed by these screws rotating simultaneously. It has a wide inlet opening that helps to discharge large or bulk materials and bridging. This feeder is used for handling materials like biomass, wet substances, large silos, bins, and powders.

Key Components of Screw Feeder:
Screw feeder suppliers in India offer equipment with a rotating screw (auger) for efficient material movement, featuring a drive mechanism, casing, hopper, and discharge end for seamless processing.
- Screw (Auger): The screw, also called an auger, is the main part that rotates to move materials. It works like a big corkscrew. Depending on what you need it for, the screw can have different shapes or designs. For example, it might have a variable pitch, which means the distance between the spirals can change. This helps in moving different types of materials more effectively.
- Drive Mechanism: The drive mechanism is usually a motor that provides the power to turn the screw. Think of it as the engine that makes the corkscrew spin. It creates the force needed to push the material along the screw.
- Casing or Trough: The casing or trough is like a container that holds the material while it’s being moved. This part keeps everything together and can come in different shapes, like round (tubular) or U-shaped. The design of the casing depends on what kind of material is being moved and how it needs to be transported.
- Hopper/Bin: The hopper or bin is where the material is stored before it goes into the screw. Imagine it as a big bowl that holds ingredients before they are mixed into a recipe. The hopper makes sure there is always enough material ready to be fed into the screw.
- Discharge End: The discharge end is the place where the material comes out of the screw feeder. It’s like the exit point where the material is released after being pushed through the screw. This is where the material is sent off to the next part of the process, whether it’s packaging, mixing, or another application.
Features of Screw Feeder:
Being well-known screw feeder suppliers in India, our screw feeders come in a variety of features based on different applications. Here are the key features of our screw feeders:
- Material Compatibility: The feeders are produced by using materials like stainless steel (SS), carbon steel, or alloys, as they can handle bulk materials such as abrasive, corrosive, sticky substances, etc. The material is highly durable and lasts for a longer duration.
- Multiple Screw Sizes and Lengths: Screw feeders are available in various sizes and lengths to meet different material handling needs. A variety of screw sizes allows for customized options for customers.
- Dust Prevention: The feeder features a sealed housing, which helps prevent dust, material leakage, and other contamination during material handling. This feature maintains hygiene and cleanliness in the feeder.
- Easy to Maintain and Clean: Screw feeders use components like removable screw sections, inspection doors, and cleaning ports, making them easy to clean and maintain. This also helps reduce downtime and enhances performance.
