A general overview of the development history of ball mills

As we all know, ball mill jar is widely used in the raw material crushing of metallurgy, chemical industry, mining, building materials and power industries. It is also one of the grinding kits of the laboratory planetary ball mill jar, used to place the samples and grinding balls to be ground. This time, Xianglong Grinding introduces the specific development history of the ball mill jar.

Traditional ball mill jars have gone through a long period of history, although ball mill jar development was difficult before, but the development after the beginning of reform and opening up was rapid. In the early 1990s, in response to the needs of ball mill jar users and manufacturers, ball mill jars began to be serialized: planetary ball mill jar stirring ball mill jar continuous ball mill jars.

Planetary ball mill jar: A new type of planetary ball mill jar which can grind raw materials with higher hardness, greatly improving grinding efficiency and effect. It adds vibration compensation, and the ball mill realizes parameter setting and control screen, load, energy input and parameter recording functions and external locks. It is also the number one choice for major laboratories currently. ball mill jar product.

Stirring ball mill jar using a spiral device, the discharge is convenient, and the degree of automation is high. It can achieve self-grinding, and compared with traditional ball mills, it extends the service life of the ball mill jar.

Continuous ball mill jar: Continuous ball mill jar due to its low unit product energy consumption, high grinding efficiency, and small footprint. Therefore, in recent years, it has been applied in China's ceramic industry, increasing the annual output of raw materials for ball mills, saving diaphragm and downtime, and saving energy consumption.

Ball mill jar is one of the grinding kits for laboratory planetary ball mill jar used to place the samples and grinding balls to be ground. So how to reduce the noise of the ball mill jar during use?

The sound insulation hood is to cover the entire ball mill jar cover, ball mill jar The material of the sound insulation hood is generally made of 2-3 mm thick steel plate plus damping material, sound-absorbing cotton, galvanized perforated plate, etc. The ball mill jar sound insulation hood must reserve material inlet and outlet channels and personnel access channels. For sound insulation effect, double-opening sound insulation doors and sound insulation windows must be installed at the inlet and outlet channels, and single-opening maintenance doors must also be installed on both sides.

The ball mill jar will generate heat during operation, so ventilation channels must be reserved. Generally, ventilation ports are set on the side and top. To ensure the sound insulation effect of the ball mill jar, silencers must be installed on the ventilation ports. Replacing the manganese steel liner with a rubber liner can change the frequency spectrum characteristics from high frequency to low frequency. If conditions permit, a sound insulation room can be designed to ball mill jar concentrated in a sound insulation room specially designed for ball mill jars, the effect will be better than the sound insulation hood, and it can effectively solve the monitoring, indoor heat dissipation and maintenance problems during the operation of the ball mill jar.
