Ball mill for preparing nano material

Abstract

The invention discloses a ball mill for preparing a nano material, and relates to the technical field of nano material preparation. The ball mill comprises a cylinder, a first base, a driving structure and a brake mechanism, and is characterized in that milling balls are arranged in the cylinder, one end of the cylinder is fixedly connected with a connecting shaft, and the other end of the cylinder communicates with a feeding pipe; and a second bearing column is fixedly installed on one side of the top of the first base, a first bearing column is fixedly installed on the other side of the topof the first base, a second bearing is embedded in the second bearing column, and a first bearing is embedded in the first bearing column. According to the ball mill, in the feeding process, feeding is conducted through a relative spiral conveying function, discharging is conducted through an air flow guiding function in the discharging process, the feeding and discharging convenience is improved,through the ball mill, the acting force between the milling balls and the cylinder is increased, the powder milling effect is improved, the ball mill has the braking function, and the idle time is reduced.

Description

technical field [0001] The invention relates to the technical field of nanomaterial preparation, in particular to a ball mill for nanomaterial preparation. Background technique [0002] Nanomaterials refer to materials with at least one dimension in nanometer size (1-100nm) or composed of them as basic units in three-dimensional space, which is approximately equivalent to the scale of 10-1000 atoms closely arranged together, because its size has been It is close to the coherence length of electrons, its properties change greatly due to the self-organization brought about by strong coherence, and its scale is close to the wavelength of light, plus it has the special effect of a large surface, so its performance Properties, such as melting point, magnetic properties, optics, thermal conductivity, electrical properties, etc., are often different from those exhibited by the substance in its bulk state. Generally, in the process of preparing nanomaterials, it is necessary to use...

Problems solved by technology

[0003] However, in the prior art, most of the ball mills used for the preparation of nanomaterials grind the materials through the balls falling by their own weight, resulting in a low force, which reduces the effect of grinding, and when most ball mills stop working, due to the inertia of the cylinder It will idle for a period of time, and at this time, you can only stop waiting, resulting in a decrease in work efficiency
