Technical Field

[0001] The utility model relates to the technical field of cyclones, and particularly relates to a cyclone device with variable angles. Background Technique

[0002] With the improvement of coal mining mechanization and the increasing mining depth, the coal output has increased significantly. At the same time, the ultra-fine components in raw coal (-0.074mm, particles smaller than this particle size) have a growing proportion. These ultra-fine components usually have a high ash content, bringing many challenges to the existing coal slime water treatment system.

[0003] The treatment of coal slime water usually adopts the flotation process. During the flotation process, the separation particle size range of conventional flotation equipment is 0.5 - 0.1mm. However, in the pulp pretreatment stage of these processes, the ultra-fine components in coal slime water cannot be effectively removed, reducing the flotation efficiency and the yield of clean coal. Many coal preparation plants in China are deeply troubled by this. Content of the Utility Model
