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 of Dual Planetary 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 jars on each smaller turntable. The machine has totally four ball mill jars installed on the smaller turntables. When the base turntable rotates, the jar roller makes planetary movements. The balls and samples of material inside the jars are ground and mixed under high speed movement.

Dual Planetary Ball Mill
01.Safety Door
Protect the inner parts of ball mill. Operation of mill jars can be clearly observed through the visual window.
02.Frequency Converter Control
ldeal operating parameters can be set according to the experimental requirements, which is simple and convenient to operate.
03.Cooling Fan Hole
High-speed operation efectively enhances airlow speed and heat dissipation speed of the machine body.
04.Four-Jar grinding
Adopted with new type pressure bar, which is exquisite, beauiful and generous, and has stable rotaton speed and high efficieny.

Features of Dual Planetary Ball Mill

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.

Dual Planetary Ball Mill
Advantagess of Dual Planetary Ball Mill

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 size of Materials: Soil or other brittle materials ≤10mm, other materials ≤3mm.
4. Wet or dry grinding method. Smallest particle size of output 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.
