Specific gravity sorting machine working principle:

The classifier, cyclone separator, dust collector and induced draft fan form a classification system. Under the action of the fan, the material moves through the inlet at the lower end of the classifier with the updraft at a high speed to the classification area. Under the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated. The fine particles meeting the particle size requirements enter the cyclone or dust collector through the clearance of the classification wheel blades, and the coarse particles sink under the action of gravity and centrifugal force. It is thrown around the cylinder by the rotor blade and slides down along the cylinder. In the process of falling, it is impacted by the secondary air flow, so that the fine powder aggregated in the coarse particles is dispersed and blown to the classification chamber again. The coarse powder is discharged by the lower discharge valve under the action of gravity.

Specific gravity sorting machine performance characteristics:

1. Vertical classification turbine device, low speed, wear resistance, low system power configuration.

2. The structure of the classifier is reasonable, and it can supply products of multiple particle size segments at the same time, which is suitable for large-scale industrial grading supply of 325~8000 mesh (1.6~45 microns) fine powder.

3. Strong applicability, can be used in series with ball mill, vibration mill, Raymond mill and other grinding equipment to form a closed cycle.

4. The system operates under negative pressure, the dust emission does not exceed 40mg/m, and the equipment noise is not higher than 75dB(A) by using noise reduction measures.

5. High degree of automation. The control system adopts program control, and the running state is displayed in real time. All levels of impeller classifier use electronic frequency conversion stepless speed regulation, automatic circulation multi-box dust collection process to achieve electronic control, automatic ash cleaning, improve the stable negative pressure of the whole machine specific gravity separator process.
