China Calcium Carbonate Powder Ultrafine Cyclone Airflow Separator Air Classifier

Calcium Carbonate Powder Ultrafine Cyclone Airflow Separator Air Classifier

Calcium carbonate (CaCO3), usually in the form of calcite and aragonite, is the most ubiquitous complex on earth. Calcium carbonate is not only the main component of marble, limestone and marble, but also found in bones, teeth, and crustacean shells, corals, muscles, snails and protozoa.

Air Classifier Features and Advantages

Available D50:1.5-25μm
The linear velocity of horizontally installed classifying wheels is up to 80m/s
Classifying efficiency (extraction ratio) can be 60%~90%
Speed of wheel is equipped with velocity sensor and can be controlled by inverter, particle size can be adjusted freely
System negative pressure operation, meet environmental requirements, noise <76dB(A)
The classifying wheel can be made of ceramic materials such as alumina, zirconia and silicon carbide, without metal pollution, meeting the requirements of high-purity materials
Grinding is completed in closed system, little dust, low noise in a clean and environmentally friendly process
PLC control system, easy operation

AIr Classifier Working Principle
Air classifier works with cyclone separator, dust collector and suction fan to form a complete classifying system. Material would go from the bottom part of air classifier up to the classifying chamber by the air flow from suction fan.
The high-speed rotation of classifier wheel would create a strong centrifugal force to separate coarse powder and fine powder.
Qualified fine powder would go through the wheel vane then into the cyclone separator or dust collector, while mixture of coarse powder and fine powder would lose its speed and fall down along the house wall to the secondary air inlet. The secondary air flow would disperse it further and separate coarse and fine powder.
Fine powder would go up to the classifying chamber for further classifying, while coarse powder would fall down and go out from the bottom outlet.
Air Classifier Technical Parameters
Widely used in chemical industry, mineral industry (especially good for calcium carbonate, kaolin, quartz, talc, mica and other nonmetallic product classifying), metallurgy industry, abrasive material industry, ceramics industry, fireresistance industry, pharmacy industry, pesticide industry, food industry, health care industry and new material industries.
