Air classifier is often used in conjunction with dry mill

Air classification is an important part of the mineral processing process, is according to the particle size of the product is divided into two parts of the operation process, classification and screening operation is different, it is not only related to the particle size, and also with the particle density and shape.air flow classifierThe treatment of dry fine-grained materials is often used in conjunction with dry mills in the field of mineral processing.

Air classifier is suitable for fine classification of dry micron grade products, which can be classified into spherical, flake and irregular shaped particles, and can also be classified into particles of different densities. The particle size of the graded product can reach D97:3~150 microns, the product particle size can be adjusted steplessly, and the variety replacement is extremely convenient. The classification efficiency (extraction rate) is 60% ~ 90%. The classification efficiency is related to the nature of the material and the content of particles that meet the particle size. The material has good fluidity, and the particle content that meets the particle size requirements is high, the efficiency is high, and vice versa.

The grading wheel has high speed and accurate vertex cutting. Multi-stage classifier can be used in series to produce products with multiple granularity segments at the same time. It can be used in series with ball mill, vibration mill, Rayon mill and other grinding equipment to form a closed circuit. The control system adopts program control, real-time display of running status, easy to operate.

The system operates under negative pressure and the dust emission exceeds 40 mg/m. After noise reduction measures are adopted, the operating noise of the equipment is not higher than 75dB(A).
