Two-way rotating ball mill smashing device for nano-material production

Abstract

The invention relates to a two-way rotating ball mill smashing device for nano-material production, wherein the device has a horizontally arranged drum; the inner wall of the drum is provided with a number of protrusions in the length direction; the middle part of one end of the drum is connected with a drum driving motor, and the other end of the drum is horizontally provided with a stirring assembly in an inserted manner; the stirring assembly includes a stirring motor, a rotating rod, stirring blades and grinding balls; the output end of the stirring motor passes through the side wall of the drum, extends to the interior of the drum and then is fixedly connected with the rotating rod; the rotating rod is provided with a number of stirring blades in the length direction, and a number ofgrinding balls are arranged evenly on the stirring blades in an embedded manner; a material inlet and outlet are arranged on the side wall of the middle part of the drum. The two-way rotating ball mill smashing device for nano-material production has simple structure, can strengthen the impact, collision, friction, extrusion, shearing and homogenization of the grinding balls on smashed materials,makes the smashing more uniform, shortens the grinding and smashing time, improves the processing efficiency of the whole grinding and smashing, and improves the economic benefits.

Description

technical field [0001] The invention relates to the technical field of nanomaterial production equipment, in particular to a two-way rotating ball mill crushing device for nanomaterial production. Background technique [0002] With the continuous development of society, nanomaterials are widely used in all walks of life. The production of nanomaterials requires multiple processes, among which grinding and crushing is an important part. Usually a ball mill is used for grinding and crushing, but after long-term use, it is found that the ball mill with this structure has a single force on the crushing, the strength is small, there is a crushing dead angle, and the crushing is uneven, resulting in a low overall crushing efficiency. Grinding and crushing personnel usually Repeated grinding and crushing will be carried out many times, which not only wastes time, but also greatly affects the overall production efficiency; usually a number of balls need to be placed in the drum o...

Problems solved by technology

Usually a ball mill is used for grinding and crushing, but after long-term use, it is found that the ball mill with this structure has a single force on the crushing, the strength is small, there is a crushing dead angle, and the crushing is uneven, resulting in a low overall crushing efficiency. Grinding and crushing personnel usually Repeated grinding and crushing will be carried out many times, which not only wastes time, but also greatly affects the overall production efficiency; usually a number of balls need to be placed in the drum of the ball mill to grind and crush the material, and the balls need to be removed from the Separation of materials is cumbersome to operate; the outer cylinder will also be worn to varying degrees during long-term use, requiring frequent maintenance by operators, which brings a lot of maintenance costs in the later period

[0003] To sum up, the existing ball mills still have great defects in structure and design, and cannot meet people's production needs for high efficiency and energy saving.
