Abstract The main body and grinding body of a large tube mill have a large load and high grinding power. When its driving device adopts a central transmission method of planetary reducer and toothed coupling, it will generate significant axial force, which affects the stable and reliable operation of the mill. The process characteristics of large tube mill drive devices using central drive, single edge drive, single edge dual drive, dual edge drive, multi-point edge drive, and other driving methods are analyzed and compared. A certain project of the a ?5.2m large tube mill with 2×4 000kW double edge transmission system taken as an example, this paper introduces the selection, design and calculation of the main motor, reducer, girth gear, and pinion, as well as the practical application of the double edge transmission system. Production practice has shown that choosing the double edge drive method for large tube mills is a preferred solution due to its convenient installation, low cost, high transmission power, and stable and reliable operation.
