Ball mill as one popular grinding equipment commonly used in chemical industry, metallurgy, mining and other industries, in the process of production, its minimum noise is 95 dB (A), up to 120 dB (A), which is one of the strongest noise in industrial production and it must be controlled.
The grinding jar is arranged eccentrically on the sun wheel of the planetary ball mill. The direction of movement of the sun wheel is opposite to that of the grinding jars in the ratio 1:2. The grinding balls in the grinding jars are subjected to superimposed rotational movements, the socalled Coriolis forces.
The Ball Mill Driving Device Fault and the Main Semantic Scholar. With rubbing and feed staff inside, when the ball mill is rotating, rubbing and feed staff are brought to a certain height. When there is no contact force between the rubbing staff and ball mill body, feed material is dropped down.
Small Particles and Particle Size. We do the method by pouring powder into a graduated cylinder then measure its weight and volume (bulk density), we then tap the container hundreds of times until it is compact then we take the mass and volume again. this process is best for large sample sizes.

Gelatinization occurs by mechanical means such as grinding, pressure, and by hot water. Soft feed at an environmental temperature of 25°C can be brought to a temperature of 85°C by the addition of 4 to 6 percent moisture from steam. Frictional heat due to passage of feed through the pellet mill adds 2 or 3 degrees of temperature.
