Efficient cement ball mill internal structure

Abstract

The invention discloses an efficient cement ball mill internal structure which comprises lifting lining plates, lifting force variable-distance devices and partition material control plates. The lifting lining plates are mounted on the inner wall of a cement ball mill barrel, the lifting force variable-distance devices are arranged at six equal division points in the circumferential direction of the inner wall of the cement ball mill barrel, the partition material control plates are arranged along the length direction of the cement ball mill barrel at intervals of certain distances, and the lifting lining plates are arranged on the remaining portions of the cement ball mill barrel. The efficient cement ball mill internal structure has the advantages that the lifting lining plates and the lifting force variable-distance devices are used with one another, novel 'L'-shaped structures are adopted, thrust can be generated for grinding media and materials when a mill rotates, and accordinglygrinding effects can be improved; the partition material control plates are arranged at intervals of the certain distances, and accordingly material running due to increase of tossing heights can becontrolled; grate gaps are spirally reserved in a distributed manner, and accordingly the problem that existing grinding media are clamped and embedded in existing grate gaps and block the existing grate gaps can be solved; the efficient cement ball mill internal structure has a good material self-sieving function and is high in discharge speed, excessive grinding phenomena can be prevented, and good ventilation and cooling effects can be realized.

Description

technical field [0001] The invention relates to a high-efficiency cement grinding internal structure, which belongs to the technical field of grinding equipment. Background technique [0002] Cement mill, also known as cement ball mill, is the main equipment for grinding cement clinker in the cement production process. The working principle of the cement mill is that the material enters the mill from the feeding device. The inner wall of the mill is equipped with a stepped liner or a corrugated liner. The mill is equipped with grinding bodies of different specifications, such as steel balls. After the ball is brought to a certain height, it falls down, causing heavy impact and grinding on the material. However, in the actual production process, the stepped liner or corrugated liner commonly used in existing cement mills has insufficient lifting height and small impact, resulting in poor abrasiveness of the mill, low output, and high power consumption. At the same time, in ...

AI Technical Summary

Problems solved by technology

However, in the actual production process, the stepped liner or corrugated liner commonly used in existing cement mills has insufficient lifting height and small impact, resulting in poor abrasiveness of the mill, low output, and high power consumption.

At the same time, in order to improve the grinding effect of existing cement mills, a certain number of activation liners are usually installed in the mill. However, the activation liners are installed in the mill in the direction of the clockwise rotation of the mill, and the activation effect is not good. The weight increases the load on the mill, and the grinding effect has not been improved much
