Laboratory air flow classifier

WORKING PRINCIPLE

The LAB Air Classifier and the feeder, cyclone separator, dust-collecting fan, induced draft fan control system is composed of a set of classification system. Under the action of negative pressure wind, the material enters directly into the grading area from above the equipment quantitatively through the feeder. Under the action of powerful centrifugal force generated by the high-speed rotating grading turbine, the coarse and fine materials are separated. The fine particles that meet the particle size requirements enter the cyclone separator or Dust Collector through the clearance of the grading wheel blades and are collected. The fine particles that meet the particle size requirements enter the cyclone separator or dust collector through the clearance of the grading wheel blade, and the coarse particles enter the secondary grading area through the fan. Under the action of the secondary wind, the third grading is carried out. Materials that meet the particle size enter the first-stage grading area through the fan for re-grading, and those that meet the particle size requirements enter the cyclone collector or dust collector through the grading wheel blades, and the separated coarse particles are discharged through the unloader.

PERFORMANCE CHARACTERISTICS

● Suitable for fine powder classification, grading product particle size up to D97:5~150 microns, product particle size stepless adjustable, variety replacement is extremely convenient;

● High grading efficiency (extraction rate)70%~90%;

● High precision classification, narrow particle size distribution, completely eliminate large particles and screen residue in the product;

● Low speed, long service life, the same grading particle size, grading rotation speed than other horizontal, vertical Classifier reduced by 50%. When producing powder with grass hardness <5, the grading wheel has no wear: when producing powder with Mohs hardness ≥7, the service life of the grading wheel is increased by 5~8 times compared with other horizontal and vertical types

● Vertical grading turbine device, low speed, wear resistance, low system power configuration:

● It can be used in series with multistage classifier to produce products of multiple granularity segments at the same time;

● Can be used in series with ball mill, vibration mill, Raymond mill and other grinding equipment, forming a closed-circuit cycle;

● System negative pressure production, no dust pollution, excellent environment, high degree of automation, strong stability, easy to operate.
