Dual Planetary Ball Mill

  • Applications:SXQM series of dual planetary ball mill is a kind of essential devise for labs, which want to mix, grind or produce high-tech new material in small lot. It is widely used in the following industries such as electronic, magnetism, medicine, ceramic,  geology, mineral, metallurgy, build material, chemical, light industry, beauty, environmental protection, and etc.

Overview of Dual Planetary Ball Mill

Double planetary structure of dual planetary ball mill realizes movement of small disk driven by one large planetary disk. Compared with common planetary ball mill in same size, revolution radius and rotation speed of mill jars have been enlarged greatly and centrifugal force of grinding balls is multiplied. Collision, shearing and frictions between grinding balls are becoming increased significantly. As result, grinding effect and efficiency have been improved greatly. Some materials can be ground into nano meter scale by dual planetary ball mill. Class. Dual planetary ball mill is a kind of typical high efficiency and high energy ball mill.

Working Principle

SXQM series planetary ball mill working principle: There are two larger planetary rollers that make rotation movement installed on a base turntable which makes revolution movement. Another two smaller turntables are installed on each larger tank rollers respectively; there are two mill tanks on each smaller turntable. The machine has totally four ball tanks installed on the smaller turntables. When the base turntable rotates, the tank roller makes planetary movements. The balls and samples of material inside the tanks are ground and mixed under high speed movement.
