Gas Flow Classification

Product Code: JL--6480

  • Technical Description:-
  • Zigzag sifters permit classification of solid compounds.
  • The solid compound being separated is charged into the feed hopper.
  • The compound is fed into the zigzag duct of the sifter at mid-height by way of a vibrating trough.
  • An air stream flows upwards through the vertical duct.
  • Depending on the geometry and density of the particles, they are carried along by the air or drop down due to gravity.
  • At every bend in the duct the solid compound passes through the air stream and falls onto the opposite wall of the sifter.
  • This corresponds to one sifting stage.
  • Owing to the flow conditions, a vortex wake is formed between two bends of the zigzag duct.
  • It ensures that the solid matter moves roughly perpendicular to the airflow.
  • In this way, a transverse sift takes place at every bend.
  • Sequencing of large numbers of such stages results in very fine separation.
  • Features a 20-stage zigzag duct.
  • Transparent material provides optimum observation of the processes in the duct.
  • A fan generates the airflow.
  • The airflow rate and the solid mass flow are adjustable.
  • The fine material transported upwards with the air stream is separated by a cyclone.
  • Pressure measurement points at the relevant positions in the trainer enable to determine the pressure loss.
  • Sand in different particle sizes is recommended for use as the feed material.
  • For particle size analyses of the feed and of the coarse and fine material, a balance and a screening machine are recommended.
  • The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
