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.


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.


Tencan dual planetary ball mill shell is welded with thick steel plate, which has high strengths, impact resistance, deformation resistance, fine workmanship, strong and beautiful appearance. The material of mechanic parts is strictly processed by heat treatment process and numerical control processing technology. The gear box is adopted with quasi-sealed groove embedded structure, and the drive gear is made of wear-resistant precision gear. The machine frame and structure are fully considered in design to ensure the stable, safe and reliable operation of the ball mill under long-term and high load conditions, and to effectively achieve the effect of noise reduction in the operation of the machine. The liquid oil self-lubricating device is designed with low noise and high intensity, and it is equipped with a liquid oil level meter for easy replacement. With the touch screen of micro-computer, machine operation is becoming convenient, the interface is more simple and intuitive,forward and reversal alternating control can be achieved easily. It owns functions of timing and power-off memory.
1. The mill pot makes two planetary movement, It enjoys high efficiency and small particle size under the high frequency percussion, linear collision force, friction force.( First in China)
2. Four different samples can be got at one time. It is convenient for the technologist to do the research and develop the new material.
3. Feed Granularity of Materials: Soil material ≤10mm, other materials ≤3mm.
4. Wet or dry grinding method. Minimum Granularity of powder amounts to 0.06 μm.
5. Frequency controlled, you can set the speed as per experiment effect.
6. Large turn disc revolution: 50-400rpm.
    Small turn disc revolution: 100-800rpm.
    Large planetary axis rotation: 100-800rpm.
    Mill pot rotation: 200-1600rpm.
7. The planetary ball mill has timing power off, self-timing forward and inversion function. It can raise the efficiency by choosing one-way, alternately, continuously, time-setting operation.
8. Motor power: 0.4L, 2L, 4L: 0.75KW, 220V, 50Hz; 16L, 20L: 5.5KW, 380V, 50Hz.
9. Our planetary ball mill is functional which has low bary center, stable performance, compact structure, easy operation, reliable safety, low noise, and low wastage.
