In the process of producing the lithium battery, the blocky battery material needs to be crushed to be a material which can be used in the next process. At present, the crushing of battery materials is generally realized by adopting two crushing wheels to select relatively, although the crushing of materials can be realized to a certain extent, the distance between the two crushing wheels cannot be adjusted in the using process, and when a large object is encountered, the machine is easy to clamp or block.

To solve the above problem, as shown in fig. 1 to 2, an embodiment of the present application provides a crushing apparatus, including: the crushing device comprises a shell 1, a linear moving assembly, a crushing wheel 9 and a crushing ring 2; wherein,

the crushing wheel 9 is arranged in the shell 1, and the crushing wheel 9 is arranged in a conical shape and can rotate around the axis of the crushing wheel in the shell 1;

the crushing ring 2 is arranged in the shell 1 and can be sleeved on the crushing wheel 9, and a crushing gap for crushing materials is formed between the crushing ring 2 and the crushing wheel 9;

the linear moving assembly is arranged on the shell 1 and is used for driving the crushing ring 2 or the crushing wheel 9 to move linearly along the axis of the crushing wheel 9, so that the crushing gap gradually changes along with the moving distance.

In this embodiment, the inside of the outer shell 1 is hollow, the upper end and the lower end of the outer shell 1 are respectively provided with the feed inlet 4 and the discharge outlet 11, and the feed inlet 4 and the discharge outlet 11 are coaxial with the crushing wheel 9. As the conical crushing wheel 9 and the crushing ring 2 are arranged in the shell 1, and the crushing ring 2 is sleeved on the crushing wheel 9. Due to the conical structure of the crushing wheel 9, its cross-sectional area varies in the axial direction. For example, when it is a forward tapered structure, its cross-sectional area gradually increases from top to bottom. While the inner diameter of the crushing ring 2 is fixed, the vertical distance between the inner surface of the crushing ring 2 and the outer surface of the crushing wheel 9 changes when relative movement in the axial direction between the crushing ring 2 and the crushing wheel 9 occurs. For example, with a downward movement of the crushing ring 2 or an upward movement of the crushing wheel 9, the spacing between the two is gradually reduced, i.e. the crushing gap is gradually reduced. The linear movement of the crushing ring 2 or the crushing wheel 9 is controlled by a linear movement assembly in this embodiment.
