By adjusting the length of the cyclone cylinder, optimizing the cone angle, and improving the geometric parameters of the sand discharge port, the cyclone can achieve the best state under various operating conditions.
Advanced structural design:
- Cyclone chamber inlet:
1.Adopts a involute inlet with spiral entry.
2.Extends the inflow channel, providing pre-classification for coarse particles.
3.Smooth transition of inlet flow velocity reduces turbulence.
- Cone:
1.Utilizes a variable cone structure.
2.The large cone angle at the upper part increases the tangential velocity of the slurry.
3.The small cone angle at the lower part prolongs the retention and classification time of the materials, improving classification accuracy.

Application conditions
- Closed-circuit grinding in the first stage
The cyclone classifier forms a closed-circuit grinding and classification system with a first-stage grinding ball mill, which has the advantages of small footprint, high classification efficiency, easy adjustment of sand return load, and more reasonable overflow particle composition.
- Closed-circuit grinding or regrinding and classification of fines or middlings
Reasonable structural design and measures such as higher inner surface finish reduce the disturbance of the internal flow field of the cyclone, effectively improving classification efficiency and accuracy.
- Concentration and dewatering of fines (or tailings)
Generally, cyclones with small cone angles or multi-cone structures are selected to obtain higher underflow concentration and underflow yield.
Cyclone characteristics
1. Higher processing capacity.
2. Longer service life of vulnerable parts.
3. Wider application range.
4. Finer classification granularity.
5. Higher efficiency.
6. Providing design and selection services.
