A ball mill for nanomaterial preparation

Abstract

The invention discloses a ball mill for preparing nanomaterials, which relates to the technical field of nanomaterials preparation, and includes a cylinder, a first base, a driving structure and a braking mechanism, and is characterized in that: the inside of the cylinder is provided with grinding balls, and the One end of the cylinder is fixedly connected with a connecting shaft, and the other end of the cylinder is connected with a feed pipe; one side of the top of the first base is fixedly installed with a second bearing column, and the other side of the top of the first base is fixedly installed There is a first bearing column, a second bearing is embedded on the second bearing column, and a first bearing is embedded on the first bearing column. In the present invention, the ball mill adopts the relative screw conveying function for loading during the loading process, and unloads through the air guide function during the unloading process, which increases the convenience of loading and unloading, and the ball mill increases The force between the grinding ball and the cylinder increases the grinding effect, and the ball mill has a brake function, which reduces the idling time.

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
