Overview of Gas Flow Classification

Gas Flow Classification is included in the Interlabs Process Control Eengineering range. The product’s intended role, construction and suitability should be assessed using the manufacturer’s or supplier’s confirmed product information and the requirements of the task for which it is being considered.

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.
