The Elbow Jet Air Classifier is the world’s first air classifier capable of performing simultaneous, multiple classifications of fine, dry powders. The Elbow Jet Air Classifier contains no rotating parts due to the fact it relies on airflow and does not contain a classifying wheel. The elimination of these parts makes the Elbow Jet ideal for abrasive and high-purity powders and makes it the perfect fit for the BioMedical and Aerospace industries. The Elbow Jet can make up to three separations at one time!
An ejector unit accelerates particles before being injected by compressed air through a feed nozzle into the classifier. Then, by the Coanda Effect*, the Jetstream will tend to flow along the coanda block. Each particle injected into the classifier has an inertia dependent on its size (mass). The smaller particles, with little inertia, will be highly susceptible to the Coanda Effect and will flow along closer to the Coanda Block.
The larger particles, with more inertia, will be less affected by the Coanda Effect and will fly farther out into the carrier air jet. Here, by setting moveable classifications edges as appropriate, particle can be classified by size with astonishing accuracy and efficiency.
