Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to an internal reinforcement structure of a ball mill casing. Background Art

[0002] Ball mill, as an indispensable and important machine in the ceramic production process, is mainly composed of a drum with a feed port and a discharge port and a drive device. The core function of the drive device is to drive the rotation of the drum, and the liner is cleverly configured inside the drum. During the rotation of the drum, these liners will finely grind the grinding material.

[0003] However, when using the existing ball mill, the grinding material must first be poured into the drum to start the grinding process. Since the grinding material contains ores of different textures and sizes, the grinding time is often determined by the most difficult ore to grind. Sometimes, even after a long period of grinding, there may still be impurities in the taken out grinding material that are not fully ground. If these impurities are used as a measure of the grinding time, the grinding time will undoubtedly be greatly extended, which will affect the progress of the entire process. These factors make the ball mill face huge challenges in determining the grinding time and ensuring the quality of the grinding material. Therefore, in order to ensure the fineness of the grinding, a long period of grinding is often required, which undoubtedly increases the energy consumption of the ball mill. How to improve the efficiency of ball milling and reduce energy consumption has become an important direction for the improvement of ball mills.

[0004] In order to solve the above problems, people have developed a high-efficiency ball mill with a double-layer cylinder structure. However, the interlayer space in the cylinder in this structure is relatively small, making it extremely difficult to install the liner on the inner wall of the cylinder. If screws are used, the installation and replacement of the liner becomes extremely inconvenient due to space limitations. If adhesive fixation is chosen, it is difficult to ensure the structural stability of the liner after installation. Therefore, how to achieve convenient installation and stable fixation of the liner under the double-layer cylinder structure has become an urgent problem to be solved in the current ball mill improvement. In view of this, in-depth research on the above problems has led to the creation of this case. Utility Model Content
