The main component of a planetary ball mill is the planetary main disc, whose design, construction, and various characteristics largely determine many key factors such as the lifespan, maintenance convenience, and operational stability of the planetary ball mill. It can be said that the planetary main disc is the high-performance "soul" of planetary ball mills.
The main disc of planetary ball mill is divided into belt drive and gear drive by transmission method. In fact, most planetary ball mills on the market now use gear transmission. Although belt drive has advantages in cost and maintenance convenience, this advantage can be ignored in the many advantages of gear drive, such as more stability, large bearing capacity, and long service life. So planetary ball mills began to be called planetary gear ball mills.
The precision requirement for the main disc of planetary gear ball mill is very high, and for rough and shoddy planetary gear main discs, they are not as good as belt driven planetary main discs in all aspects. The general processing method for planetary main discs: gears are purchased from external sources and then turned, while sun discs use wire cutting technology, which can reduce costs but lacks accuracy, stability, and lifespan.
The gears of the planetary main disc produced by a professional planetary ball mill manufacturer are customized by the gear factory, with first turning and then milling the teeth. Other accessories are processed using CNC to achieve precision fit. Although the cost is higher, the effect is outstanding, and the quality of the entire machine has reached more than one level.
