the small type ball mill in Our country has become a series and can meet the needs of various industries, but there is a wide gap with foreign countries in a large ball mill manufacturing areas . The maximum size of the gear traditional ball mill in the world is made a company which headquartered in Finland Metso Minerals (Metso Minerals) , its applied products’ specifications in the copper gold and silver mine in the Chi Li Aisi hole, Dida (Escondida) is φ7.32 m x10. 52 m, power is 448 kW which drived by two low-speed synchronous motor ; its another application in the Telfer gold mine of Australia is φ7.47 m x11.43 m. power is 13 000 kW, drived by two-motor ,built and put in to use in 2004. Ani Group’s products – largest mill in Australia’s specifications is φ6.706 m x13.106 m, the installed power is 1000 kW. The Representative type is Fuller Company products- φ6.70 mxll.00 m ball mill and the Finnish Fenma a mine pump pull (of Rauma – Repa-la) for the company of the western Soviet Union he leaves Nickel Mining and Dressing Manufacturing Taiwan φ6 .50 m x9.65 m ball mill, the gear is an integral whole with the simplified 9 650 kW by the ring motor.Machine prototype in Germany Wa Lanjie iron ore operation for five years for dealing with difficult to grind the ore to the maximum design capacity of 000 t / h. Handled a total of 250 million tons of ore, the total cost of grinding a 30% reduction in . This oversize mill journal bearing instead of at both ends of the newly designed around the simplified large pad bearings at both ends of the mill will enable almost no load, extending bearing life.
Although the large mill in proportion can increase the processing capacity of the mill, but it can also bring a variety of mechanical design and mechanical manufacturing problems, these problems will have even greater impact on the ball mill and SAG mill. to our country such a country whose industrial development level is not very high, the large mill still has many difficulties nowadays .Therefore, the development direction of the mill should has been turned to the large-scale energy-efficient direction.
