Hydrocyclone is a very important classification, concentration, and dehydration equipment in mineral processing operations. If the hydrocyclone is not properly designed and installed in the mine, it will directly affect its work efficiency. Generally, the factors that affect the work efficiency of the hydrocyclone mainly include nine aspects.

Nine factors affecting the efficiency of hydrocyclones:

1. Cyclone diameter

The diameter of the hydrocyclone is an important condition that affects its working efficiency. The larger the diameter of the hydrocyclone, the larger the production capacity and separation particle size.

2. Cone angle

The working efficiency of the hydrocyclone decreases as the cone angle of the cyclone increases. The greater the angle of the cone of the water flow cyclone, the greater the resistance, which affects its production capacity.

3. Feeding pipe diameter

The diameter of the feed pipe of the hydrocyclone has a certain effect on its processing capacity and classification efficiency. Generally, the larger the diameter of the feed pipe, the greater the processing capacity.

4. Diameter and wall thickness of overflow pipe

When the inlet pressure of the hydrocyclone is constant, the diameter and wall thickness of the overflow pipe is proportional to its production capacity.

5. The shape and size of the inlet

Generally, the cut surface shape of the feed opening of the cyclone is mainly divided into two types: circular and rectangular. The feed port can convert the linear motion of the liquid flow into circular motion at the entrance of the column section. Therefore, the shape and size of the feed inlet of the cyclone directly affect its production capacity and separation efficiency.

6. Diameter of underflow port

The larger the diameter of the underflow orifice of the cyclone, the finer the grading particle size. However, its production capacity increases as the diameter of its underflow orifice increases.

7. Roughness and assembly accuracy

In general, the inner surface roughness and assembly accuracy of the hydrocyclone has little effect on its production capacity and separation efficiency. However, through research and practice, it is found that if the hydrocyclone is lined with wear-resistant rubber, it will increase its flow resistance and increase its separation efficiency.

8. Feed viscosity

The production capacity of the hydrocyclone will increase due to the increase in the viscosity of the feed.

9. The ratio of the diameter of the underflow port to the diameter of the overflow port

The ratio of the diameter of the underflow port to the diameter of the overflow port is called the cone ratio. The cone ratio is an important parameter for the design of the cyclone. In general, the larger the cone ratio of the hydrocyclone, the smaller the grading particle size.
