Constant-temperature ball milling tank

Abstract

The invention provides a constant-temperature ball milling tank, comprising a sandwich ball milling tank, a ball milling tank cover capable of admitting or discharging a fluid, and a rotary joint connecting the ball milling tank and a fluid pipeline; the ball milling tank cover at the center of the bottom outer wall of the ball milling tank is of through hole structure, and a through hole connects with the fluid pipeline on two sides through the rotary joint; the fluid includes gases or liquids at different temperatures; by enabling the fluid at specific temperature to flow continuously in a sandwich layer of the ball milling tank, it is possible to keep inner temperature of the ball milling tank constantly to a required temperature; the constant-temperature ball milling tank enables powdery material to be ground or mixed at precise low temperature or high temperature.

Description

technical field [0001] The invention relates to a ball mill jar, in particular to a ball mill jar used in a ball mill and utilizing fluid flow to maintain a constant temperature. Background technique [0002] The ball mill is a preparation equipment used to mix or grind powder in the ceramic industry. The mixed or ground powder and the ball milling medium are placed in the ball mill tank, and the ball mill roller drives the ball mill tank to rotate at a certain speed, so as to achieve powder Grinding of materials or mixing of various powders. Ball mills are widely used in the preparation of materials such as ceramics. [0003] Sometimes, we need to mix or grind powders at a specific temperature different from normal temperature. For example: when using amorphous iron powder to prepare nanocrystalline iron powder, as the ball milling progresses, the temperature of the powder increases gradually, and the phase of the iron powder often changes from nanocrystalline to crystal,...

AI Technical Summary

Problems solved by technology

Although there are ball milling tanks with heat preservation, for example, the utility model patent with the authorized notification number CN 204051804 U discloses a kind of filling insulation material to realize ball milling at very high temperature, but as the ball milling progresses, the temperature in the ball milling tank will continue to rise. Cannot keep the milling temperature at the required temperature

In addition, although most vacuum ball mill tanks have a certain heat preservation function, the heat preservation effect is weak. The fundamental purpose is to maintain a certain atmosphere or to escape the gas generated in the ball mill. ball milling, but it is difficult for vacuum ball milling to keep the ball milling temperature at the required temperature
