The airflow classifier is often used in conjunction with the dry mill

Air flow classification is an important part of mineral processing. It is an operation process that divides products into two parts according to different particle sizes. Classification and screening operations are different. It is not only related to particle size, but also related to particle density and shape. Air classifier is often used with dry mill in mineral processing field to handle dry fine materials

The air flow classifier is applicable to the fine grading of dry micrometre products. It can grade spherical, flaky and irregular particles, as well as particles with different densities. The particle size of graded products can reach D97:3~150 microns, and the particle size of products can be adjusted steplessly. It is extremely convenient to change varieties. 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 requirements. The material has good fluidity. The efficiency is high if the content of particles that meet the particle size requirements is high, and vice versa< Br/>The grading wheel has high speed and accurate vertex cutting. Multi grade graders can be used in series to produce products with multiple particle size segments at the same time. It can be used in series with ball mill, vibration mill, Raymond mill and other grinding equipment to form a closed cycle. The control system adopts program control, and the running status is displayed in real time, which is easy to operate< Br/>The system operates under negative pressure, and the dust emission is over 40mg/m. After noise reduction measures are taken, the equipment operation noise is not higher than 75dB (A)
