Description

Technical Field

[0001] The utility model relates to the technical field of cement mills, in particular to a cement mill with an adjustable installation of activation rings. Background Art

[0002] A mill for producing cement generally includes a cylinder body and grinding media arranged inside the cylinder body. Liners (activation rings) are used to protect the cylinder body from direct impact and friction of the grinding media and materials. At the same time, different forms of liners (activation rings) can be used to adjust the movement state of the grinding media, so as to enhance the crushing effect of the grinding media on the materials, help improve the grinding efficiency of the mill, increase the output, and reduce metal consumption.

[0003] Most of the existing activation rings are fixed to the cylinder body by bolts one by one during installation. When installation interference occurs during the installation of the last monomer structure, it is necessary to disassemble the already fixed monomer structures again for position adjustment to ensure the successful installation of the last monomer structure, resulting in poor adjustability during the installation process of the activation rings. Therefore, the utility model proposes a cement mill with an adjustable installation of activation rings to solve the deficiencies in the prior art. Summary of the Utility Model
