(1) The influence of feed pipe diameter dG on the work of cyclone
The size of the ore feed port has a certain influence on the processing capacity, separation size and classification efficiency. Its diameter is often proportional to the cyclone diameter, mostly dG=(0-08-025)D. The shape of the cross-section of the feed opening is rectangular.
(2) the impact of the overflow pipe diameter dY on the hydrocyclone work
The size of the overflow pipe should be inverted with the diameter of the flow converter, generally dY=(0-2~0:4)D. Increase the diameter of the overflow pipe, the posthumous flow increases, the overflow particle size becomes rent, the fine grain level in the sinking sand is reduced, and the concentration of the sinking sand increases.
(3) The influence of the diameter of the sand settling mouth dY on the work of the hydro cyclone
The diameter of the sand sedimentation mouth is often compared with the diameter of the overflow mouth is called the angle cone ratio. The test concluded that the angular cone ratio of 3 to 4 is appropriate, it is an effective means to change the classification of particle size. The sand sink mouth often increases the discharge area due to wear, so that the sand sink output increases and the sand sink concentration decreases. If the sand sink mouth is too small, the coarse particles accumulate more and more at the top of the cone, which will cause the sand sink mouth to be blocked.
Fine grading or dewatering with a smaller cone angle, at least up to 100 ~ 150; coarse grading or concentration with a large cone angle, up to 200-450. cyclone cylinder height five generally take h (0.6 ~ 1.0) D. posthumous flow tube insert depth hy, for (0-7 ~ 0-8) h, too long or too short. Both too long or too short will cause the posthumous flow running coarse.
(5) The influence of feed pressure on the work of cyclone
Increase the feed pressure, the pulp flow rate increases, which can improve the classification efficiency and sand concentration. When dealing with rent grain material, low pressure (0-05-) should be used as far as possible; only when dealing with fine grain and muddy material, higher pressure (o1~03MPa) should be used. Feeding method can be used to stabilize the box or sand pump direct feeding, the latter is more effective from the perspective of energy saving and stable operation.
(6) The influence of ore feeding nature on the work of hydro cyclone
When the concentration of feed ore is high, the classification size will become rent, and the classification efficiency will be reduced. When the grading size is 0-074mm, the concentration of feed ore is 10%-20%; when the grading size is 0-019mm, the concentration of feed ore should be 5%~10%.
