Because of it, much attention has been paid to the maintenance. This paper proposes the concrete design, in view of the cooling system of Mandrill. According to the requirements and the fundamental principle of cooling system, the paper chose the first asa selection of the design, bya detailed analysis parison of working principle ,as well as advantages and disadvantages of the three proposals. Through consultancy to relevant materials, analysis and calculation the paper determines the model of motors, reducers, shaft, coupling, keys, and other important parts,and checks up the important parts. On this basis, then design the structure of other non-ponents, such as, rotating on the feeder, move steel and other ponents etc. According to the above method, the task of cooling mandrel rotation can plete well 【 17 】.
