Air Classifier
Suitable for separating particles of different sizes
Suitable for separating particles of different sizes
- Air Classifier uses centrifugal force, gravity and inertial force to separate particles of different sizes in a medium (usually air)
- A variety of classifier rotors are available with adjustable output and speed which can be adjusted by frequency conversion
- Complete closed loop grinding system, resulting in no dust overflow or environmental pollution with low noise levels and easy operation
- Can be connected in series with grinding equipment such as ball mill, vertical mill or Raymond mill to form a closed loop system
- Ceramic grinding rotor available for high purity products with no metal pollution
- Explosion-proof design and nitrogen circulation, suitable for inflammable, explosive or oxidizable materials
The material enters the classifier through a feed inlet at its lower end and is then propelled upwards by suction from a fan. As it passes through the classifier, it is subjected to strong centrifugal forces generated by a rapidly rotating turbine. Qualified fine powders pass through blade on the classifier into a cyclone separators or dust collector for collection. Some fine powders carried by course particles collide with walls and fall back down towards secondary air inlets along the cylinder wall. Coarse particles are separated from finer ones due to strong elutriation from secondary air flow; fine particles rise up for further grinding while coarse ones fall out at discharge ports.
