Screw Conveyor

Screw conveyors are a useful and pretty simple material handling tool for transporting bulk materials to a uniform or sloppy plane.

One of their primary jobs is breaking any chunks in the material. They are used to convey various types of material. Be it dry, coarse, sluggish, thick, liquid, a screw conveyor can deal with them without a glitch.

The materials are moved in a set quantity from the entrance till its way out. At the inlet, materials are organized based on the size and strength of the conveyor.

Applications

The screw conveyors are useful in various applications due to its effective working methodology and excellent outcomes. Some of them are:

Screw conveyors are most popular in the bulk material handling industry to shift bulk materials between different points at a controlled and even rate.

In several manufacturing industries, ordinary filters, jet pulse filters, or dust collectors are used to gather the dust from production chains. Here, screw conveyors play an essential role in removing the accumulated dirt.

In some of the major industries, screw conveyors are used for processes like feeding, mixing, batching, and grinding.

Screw conveyors are used in the agriculture industry in the form of agricultural tools like threshers and balers.

Other applications of screw conveyors, according to multiple industries, is as follows:

  • Chemical Processing
  • Mining and Mineral Operations
  • Power Plants
  • Wastewater Facilities
  • Food Industry Equipment
  • Grain Handling
  • Cement Mixers
  • Iron and Steel Factories
  • Paper Industry

How does it work?

  • A screw conveyor is a helical screw-shaped blade mounted on a shaft. Their function is identical to that of screws.
  • It is connected around with a tube or U shaped trough that acts as the conveying surface. Sometimes, this trough is guarded by a cover to ensure the process is cleaner.
  • The conveyor is provided with a feeder device at one end from where the materials are put in. When a drive motor attached to the conveyor is run, this assembly starts rotating.
  • The supplies are then added at the feed end of the device, from where they begin moving forward with each spin and can be taken out at the release end.

Technical Features

Parts used in Screw Conveyors:

  • Conveyor Screw
  • Job Rated Components
  • Jig Drilled Couplings
  • Tem U-lac Self-locking Coupling Bolts
  • Hanger & Bearings
  • Trough Ends
  • Troughs, Covers, Clamps & Shrouds
  • End Flange
  • Discharge Spouts
  • Supporting Feet & Saddles

The conveyor screw is an essential part of screw conveyors. It provides motion to the material while revolving inside the trough. It can be helicoid, sectional, or any other unique design as per the requirements of our work.

Coupling is provided to connect the shaft with the motor. It transmits rotation and energy to the screw conveyors. They maintain their position with the help of self-locking Tem-U-Lac bolts.

Bearings are fitted at both ends of the conveyor. For the shafts are usually long, hanger bearings are also provided to maintain alignment of the shaft and support it while rotating.

The entire screw conveyor unit is backed by the trough ends and by either feet or saddles at intermediate positions.

Troughs and covers enclose the material and the rotating shaft entirely. There are a variety of troughs available: U-trough, Flared trough, Tubular trough, Rectangular trough. According to the trough, covers are chosen to guard it.

Trough ends support the conveyor drive and end shafts from any tolerances.

Inlet and Discharge spouts may be fitted with either end of the conveyor. Inlet spout entrance while the discharge spout is the exit gate of the materials. In some of the conveyors, more than one inlet or discharge spouts with curve slides are present to feed and distribute materials.
