DESCRIPTION. The DYNAIR is a Double Whizzer Dynamic classifier. This type of separator is usually installed on Pendulum Roller mills but can be used in a pneumatic circuit, alone or combined with a Pulverizer or Ball mill with the possibility of recycling the over sized particles.

By altering the classifying wheel speed, the particle size can be easily adjusted even during operation. Fine particles whose size is below the set cut point are transported through the rotor blades along with the classifying air, are then discharged via the fines discharge in the main air flow, and finally collected in a suitable filter.
Williams High Efficiency Turbine Air Classifiers can help increase production rate from various grinding mills including vertical roller mills, ball mills, and others. These high efficiency air classifier mills can achieve 80% efficiency while producing 70% minus 200 mesh and 70% efficiency when producing 95% minus 200 mesh (74 ...
The materials are fed into via the bottom roller by force of induced draft fan and then mixed with first air to disperse particle and then brought to classifying zone, Owing to the high speed rotary of classifying rotor,the particle is affected by the centrifugal force produced by the classifying rotor and centripetal force generated from induced draft fan.
5057 Raymond® roller mill with MCS 250 high efficiency turbine classifier. The whizzer separator originally supplied in the 1950's with this mill was replaced in 1993. With an optimized airflow the mill achieved a 40% increase in capacity when grinding kaolin clay to 99.9% minus 325 mesh.
Air classifiers are often used in closed circuit with grinding mills, such as ball mills, hammer mills, roller mills or jet mills. The air classifier is used to select the onsize material and return the oversize to the milling system. External air purged classifier rotor seal insuring clean topsize cuts.
