    Screw Feeders

    Screw feeders are used for the airlock, pneumatic conveying in high velocity, metered drop-through, feeding, and many point connections. We also have screw feeder designs for specialized injection solutions with screw designs for compaction, airlock & feeding of various materials like fine powders, pellets, coarse powders etc.

    A screw feeder is a vital piece of equipment that is used to deliver granular or fine substances based on your requirements. The capacity of bulk material or feed rate can be controlled to a more accurate degree with the help of a screw feeder.

    As the best screw feeder manufacturer in India, we offer quality products that provide long-lasting service and less maintenance, low cost, low power consumption, and cost-effective and robust technique.

    The Basic Designs Of a Screw Feeder:

    The basic design for most screw feeders features a screw conveyor that is fed by another conveyor, and the amount of discharged material is directly proportional to the amount of material introduced at the inlet. The inlet is always flood loaded and is mostly mounted directly to some form of storage device such as a silo, hopper or bin.

    To guarantee even and efficient cycling, many factors must be considered when designing a screw feeder. During each revolution, the bulk material is supposed to move from one flight to the next to reach the discharge. If a screw feeder is improperly designed, it can cause problems such as stagnant materials that affect the productivity of the system. to ensure that the flow of the bulky materials is smooth, each flight increases the available volume as the screw must progress towards the discharge.

    The Basic Types Of Screw Feeders:

    Variable or Stepped Pitch

    As it progresses towards the discharge of the screw feeder, the pitch varies from shorter to longer. To create more available volume for the addition of bulk materials from the hopper every pitch grows in length in the inlet section. With a stepped pitch, the flight pitch changes in increments.

    Tapered Outside Diameter

    The outer diameter of the screw is narrowed from the back end of the inlet opening to the shroud. This helps create additional volume available for the extra bulky materials from the hopper.

    Mass Flow

    Jenike & Johanson developed the mass flow design. It is a combination of variable pitch and tapered inside diameter. A pointed cone is situated in the centre of the pipe. The short pitch flights are mounted on the cone to create additional volume for the additional bulk materials from the hopper. Variable pitch is added tothe screw starting where the cone ends and continuing to the discharge.

    High speed & Low speed screws

    Screw feeder designs can be either high speed or low speed depending on the application and the process. Both of these have certain advantages & disadvantages, and the selection of the type of design methodology depends on the application.
