The SQM series variable - frequency planetary ball mills produced by our company are equipped with four ball - milling jars on the same turntable. When the turntable rotates, the ball - milling jars revolve around the axis of the turntable while rotating around their own axes, performing a planetary motion. The grinding balls in the jars collide with each other during high - speed movement to grind and mix the samples.This product can grind and mix products with different particle sizes and materials using both dry and wet methods. The minimum particle size of the ground products can reach 0.1 micron (i.e., 1.0×10⁻⁴ mm).

Program-controlled (with electronic monitoring)） | The ball mill is controlled by a high-tech microcomputer chip. It can operate alternately between forward rotation and reverse rotation according to the set program (0 - 999 minutes), and also operate alternately in the sequence of forward rotation, pause, reverse rotation, pause, and forward rotation (0 - 999 minutes). It is especially suitable for the needs of cooling or intermittent operation. |
Product Features:
1.The gear transmission overcomes the drawbacks of the original belt transmission, such as easy slipping and unstable rotation speed.
2. It not only maintains the stability of gear transmission but also overcomes the disadvantages of the original belt transmission, such as easy slipping and unstable rotation speed.
3. The grinding jars adopt a planetary motion, resulting in high ball-milling efficiency and fine particle size.
4. With frequency conversion control, the ideal rotation speed can be selected according to the experimental results.
5.The frequency converter has under voltage and over current protection functions, which can provide necessary protection for the motor.
6.As a whole, it has the functions of timed shutdown, automatic timed forward and reverse rotation, and can freely choose one-way, alternating, continuous, timed and non-timed operation modes as needed, improving the grinding efficiency.
7.Four samples with different sizes and various materials can be obtained simultaneously in one experiment.
8.It has a low center of gravity, stable performance, compact structure, convenient operation, safety and reliability, low noise, no pollution and low loss.
9.The equipment is equipped with a safety switch to prevent the equipment from starting when the safety cover is open, so as to avoid safety accidents.
10.Since the grinding jars of the horizontal planetary ball mill are horizontally installed and have no fixed bottom surface during rotation, the problem of sedimentation of some materials is well solved.
