   Hydrocyclone The height has a great influence on the classification accuracy and classification ability. And increase the height of the cylinder to increase the classification ability. Under normal conditions, the height of hydrocyclone is closely related to the inner diameter of hydrocyclone. Hydrocyclone Height vs Hydrocyclone The ratio of inner diameter should be 1.5-1.8 times.   Hydrocyclone Length selection: Hydrocyclone The length of classification has a great influence on the classification granularity. In a reasonable range, increase the length of the cone and increase the classification area to improve the classification. However, if the length is too long, it will be classified. Worse.
Actual production conditions in the actual production process, there are mainly large fluctuations in the coarse ash content of clean coal and small caliber Hydrocyclone The feed pressure is unstable and flotation is rough. Due to the fluctuation of ash particle size of coarse fly ash, the feed pressure of cyclone separator is unstable, and the particle size composition of overflow flow changes Hydrocyclone The pressure of the group is not stable, which will lead to large fluctuation of the grading particle size, leading to the coarsening of overflow particles and affecting the separation effect of flotation. What factors will affect the separation effect of cyclone separator?
Concentration: when Hydrocyclone When the size and pressure are constant, the feed concentration has an important influence on the overflow particle size and classification efficiency. When the feed concentration is high, the viscosity resistance of the fluid increases, the size of the grading becomes coarse, and the classification efficiency decreases. Feed size: the change of feed size will significantly affect the classification effect of hydrocyclone. When other parameters are constant, when the content of the feed smaller than the grading size is small, the content of fine particles in the underflow is small and the concentration is high, while the content of coarse particles in coarse particles is high.  
Overflow increases, Hydrocyclone When there are many materials close to the grading size, there are many fine-grained materials in the underflow and many coarse-grained materials in the overflow. The cross section area of cyclone separator is calculated, and then the scale of mine mouth is determined according to the fault area. Selection of standard inner diameter of cyclone separator: Hydrocyclone The inner diameter of the operation and Hydrocyclone The proportion of the feed port is related. This point should be taken into account when selecting the cyclone separator standard, so that the operation diameter of cyclone separator is consistent with the scale of feed inlet. Selection of cyclone height.
