Pellet Mill

Basically the purpose of pelleting is to take a finely devised, some time dusty, unpalatable and difficult to handle feed material and by application of heat, moisture and pressure form it into larger particles. These larger particles or pellets are easier to handle, more palatable and usually result in improved feeding results when compared to mesh feed.

The modern type pellet mills use a ring type die turning about two fixed rollers, with the die and rollers mounted in a vertical plane and consist of following component parts:-

  1. Feeder

  2. Conditioning chamber

  3. Pelleting device

  4. Speed reduction device

  5. Prime mover

  6. Base

The feeder is screw type and is equipped with a variable speed electric drive for speed control. The purpose of the feeder is to provide constant, controlled and even flow of feed to the mixing and pellet in operation. Any variation in this flow results in poor conditioning and a variable product.

Conditioning is accomplished by the addition of controlled amounts of steam. Addition of steam supplies moisture for lubrication, liberates natural oils and in some cases results in partial geletinisation of starches.

In the pelleting unit the conditioned mash is forced through perforations in the die by roller pressure and gets compressed and forms into pellets. Adjustable knives cut pellets into desired lengths.

As the die speed is always less than the motor speed, speed reduction is provided through V-belt drive.

SPECIAL FEATURES OF 'PREMIUM' PELLET MILL

  1. Powerful permanent magnet is provided at the entrance to remove scrap iron particles from feed before they reach Die and Rolls and hence prevent damage to costly components.

  2. Screw feeding conveyor and down spout are made from stainless steel to avoid corrosion due to steam and molasses. The feeder is designed to provide uniform food to pellet mill.

  3. Die and Rolls are accurately machined from special alloy steel properly heat treated to ensure long life.

  4. Doors, Windows and hinged covers are provided to facilitate cleaning and easy accessibility to Die and Rolls.

  5. Correct selection of all bearings, balancing of V-pulleys, selection of V-belts and accurate machining of all components not only ensure proper capacity, but lower the operating costs.

  6. Shear pin has been provided to protect mill from over loading.

  7. The design of steam chamber and location of cutters have been provided scientifically to ensure correct distribution of dry stream and to maintain correct size of pellets
