Ultra Fine Powder Air Classifier Grinding Mill Mechanical Pulverizer ISO

Ultra-fine Powder Mechanical Pulverizer High Quality Air Classifeir Grinding Mill

Air Classifier Mill, also called Air Classifying Mill and Dynamic Classifier Mill, represents one of the most  universal milling

systems available. With its combination of an impact milling rotor and an integral dynamic classifier, each with independent variable speed drives, the MJW can process a variety of materials and produce a wide range of particle sizes. By simple adjustment of the classifier speed, the air classifier mill  can make various cut points of 20 – 120 µm typically. Manufactured

in both carbon steel and 304/316L  stainless steel, the classifier mill is used in all industries from chemicals and minerals to

food and  pharmaceuticals. 

For potentially explosive materials PSR11 (pressure shock resistant) mill design is available,

alternatively the mill system can be designed for pressure venting or nitrogen inerting. A special pharmaceutical design is 

also available with fully enclosed motors and suitable for CIP.

The air classifier mill is made in a range of sizes from laboratory/pilot scale with 7.5kW mill drive motor

to production mills up to 250kW. Airflows are higher than standard pin mills or turbine mills, which has

the advantage of rapid heat dissipation and makes the DCM suitable for heat sensitive materials.

Material is fed into the air inlet bypass duct by an inverter controlled feeding device, and then

pneumatically conveyed into the classifier mill. On entering the mill, material is first presented to the

classifier and any “in  spec” material passes directly through the classifier with the conveying air to the

product filter.

Coarse material rejected by the classifier falls into the grinding zone between the rotor hammers and

surrounding grinding track. Size reduction takes place until the particles are fine enough to be ‘picked 

up’ by the mill internal airflow and are presented once again to the classifier. This internal recirculation

is repeated until the material is fine enough to pass through the classifier and exit the air classifier mill.

The product is separated from the conveying air in the filter. The product discharges through a rotary

valve and the clean air passes through the filter elements to the system fan and to atmosphere.

To ensure customer confidence in the capabilities of our equipment and processes, we operate a

 comprehensive pilot plant in Qingdao city, China, which includes the Air Classifier Mill, where we can

 run milling trials on your materials.
