Planetary ball mill is a standing grinding instrument that is often used in laboratories to grind various types of solid samples. It uses planetary ball milling to drive the ball mill jar to rotate, and then achieves fine grinding of samples through strong friction and extrusion of grinding balls.

Many users who use laboratory ball mills feel that the noise generated during their operation is relatively loud. In fact, this perception is relatively one-sided. The sound produced by the laboratory ball mill mainly comes from two aspects. One is the sound produced by the grinding ball when it hits the ball mill jar, and the other is the sound produced by the instrument during transmission. The transmission methods of laboratory ball mill on the market can be divided into two types, gear type and belt type, and the sound generated by gear transmission is relatively loud.

At present, the decibel value of the sound produced by the ball mill with gears as the transmission method far exceeds the limit that the human body can bear. If we work in such a noisy environment for a long time, it will cause damage to our hearing system. The laboratory ball mill, the power part of which adopts a compound belt drive, adds a tensioner design. The sound generated during grinding is about 70dB, which is within the comfortable hearing range of the human body, so that you will no longer be troubled by noise.
