The grinding jars are 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 (or 1-2.5 or 1-3). The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so-called Coriolis forces.

Empty the mill charge and sand into the ball try once grinding is complete. Clean out the mill using a brush. Put the lid on the mill. Brush the sand from each Ball and place the clean Balls onto a pan.
Nov 18, 2008 Basic principle Ball mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system. There is a
The effect of trace impurities in G-2 on engineering materials has yet to be verified. Microscopic analysis and comparison of the two samples showed that the folds of sample DY-1 are more dense, which indicates that the G-2 prepared by the vibrating ball mill was significantly better than the DY-1 purchased on the market.
Ball mill is mainly used for grinding in mining (metallic minerals and non-metallic minerals), cement, refractories, chemical, power plant, aluminum, building material, glass, ceramic, steel slag and fly ash, ect.
