mineral separator multi-rotor ultrafine air classifier

INFORMATION DETAILS

The QLFD air classifier is composed of a grading system with the feeder, cyclone Collector , dust-collecting fan and induced draft fan control system. Materials under the action of negative style speaks through quantitative from directly above equipment feeder into the classification zone, rotating at high speed grading turbine generate powerful under the action of centrifugal force makes the thickness of the material meet the requirements of the particle size of fine particle separation through hierarchical wheel blade clearance into the cyclone or filter collection, coarse particle entrainment part of fine particles by hitting the fan in the second secondary classification under the action of wind, 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. The material that meets the particle size enters the first-level grading area through the fan and is graded again. The material that meets the particle size requirements enters the cyclone collector or dust collector through the grading wheel blade, and the separated coarse particles are discharged through the unloading device.

PERFORMACE FEATURE

● It is suitable for fine grading of powder, the particle size of graded products can reach D95:5 ~150 microns, the product particle size can be adjusted continuously, and the variety replacement is extremely convenient

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

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

● Low speed, long service life, the same graded particle size, graded rotation speed than other horizontal, vertical classifier reduced by 50%. When producing Mohs hardness <5, the grading wheel has no wear; When producing Mohs hardness >7 powder, the service life of grading wheel is 5~8 times higher than other horizontal and vertical types;

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

● Multi-stage classifier can be used in series to produce products with multiple particle size segments at the same time;

● Can be used in series with ball mill, vibration mill, Raymond mill and other grinding equipment to form a closed loop:

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