The ball mill is mainly composed of feeding part, discharging part, rotating part and transmission part (reducer, small transmission gear, motor, electric control) etc. The hollow shaft adopts steel castings and the lining can be removed. The big rotary gear is manufactured by adopting steel castings; the wear resistance liner is inlaid in the cylinder with excellent abrasive resistance. This machine possesses features as stable operation and reliable work.

Up to now, pumps, valves and hydraulic components (ball mill) needed in small engineering machinery basically rely on import. The foreign corollary parts enterprises should first satisfy the demands from its domestic enterprises. Second, they should also meet the demand of the foreign-funded enterprises in China. At last, the demands from Chinese enterprises should be considered. The restrained affect from this situation on our engineering machinery enterprises is going to become more and more evident. Among the engineering machinery enterprises this year, it has taken as long as a year and a half for some of them to pay off the money to the foreign corollary enterprises.

In order to realize a comprehensive development in small engineering machinery corollary parts including mini excavator, it is important to achieve hydrostatic transmission. At this moment, among the small engineering machinery like compact wheel loaders, backhoe loader backhoe, skid steer loaders, telescopic handler and small tonnage forklift etc., the hydraulic parts needed by the supporting model of those hydrostatic transmissions mostly depend on import. Internationally, loaders under three tones basically realize hydrostatic transmission in developed countries, while loaders produced in our country at an annual output of hundreds of thousands of units almost still adopt hydraulic transmission.

At present, the domestic engineering machinery especially the small ones has a broad market prospect. The market prospects of the small excavator are optimistic, besides, the markets of telescopic handler and Skid Steer Loaders are in the process of being cultivated as well, which are about to have a better development. In view of the whole development and current specific situation of the engineering machinery in our country, the professionals suggest that the mini excavator and other small engineering machinery corollary parts should become the breakthrough to promote the complete development of the corollary parts industry in our engineering machinery.

According to materials and the discharging ways, you can choose dry ball mill and wet grid ball mill. The energy-saving ball mill adopts self-aligning double row spherical roller bearings, whose running resistance is small and the energy-saving effect is obvious. As for the cylinder, a cone cylinder added to the original cylinder not only enlarges the mill’s volume but also rationalizes the medium allocation inside. This product is widely used in the dressing plant of non-ferrous, ferrous and non-metalic metals as well as the grinding of the materials in chemical industry and building material industry.
