Abstract

The present invention provides a hyperbolic three-adjustment tumbling ball mill, which relates to the technical field of ball mills. The hyperbolic three-adjustment tumbling ball mill comprises a base and a grinding cylinder. In the present invention, the first rotating shaft and the second rotating shaft rotate to drive the material in the grinding chamber to move to form a first motion curve, and then the first rotating shaft axis and the center of the grinding cylinder form an angle to form a second motion curve of the material, thereby improving the material cutting rate and collision probability. The grinding chamber can be evacuated into a vacuum state by a vacuum pump, and can be connected to each group of gas sources through a second pipeline through a diverter, so that the grinding chamber can be adjusted to a vacuum state or various gas-filled states. Low-temperature gas can also be introduced through the second pipeline to quickly adjust the temperature. The tumbling speed can be adjusted at any time according to different material requirements. The inclination angle of the grinding cylinder can be adjusted by a lifting component to achieve the three-adjustment effects of temperature adjustment, speed adjustment and angle adjustment. A dust removal box is arranged between the first pipeline and the vacuum pump to effectively collect dust.
