### Ball mill

A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a so called sun wheel. The direction of movement of the sun wheel is opposite to that of the grinding jars (ratio 1 2 or 1 1). The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so called Coriolis forces.

### Mill (grinding)

Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing, one example being the Sepro tyre drive Grinding Mill. Industrial ball mills can be as large as 8.5 m (28 ft) in diameter with a 22 MW motor, [4] drawing approximately 0.0011% of the total world's power (see List of countries by electricity consumption ).

### How to check the ball mill load? Bailing Machinery

Therefore, the noise intensity of the ball mill can be utilized to evaluate the material load in the ball mill. Acoustic detection of ball mill load can be used for both wet grinding and dry grinding, which can improve the grinding capacity and the fineness of the product, and save steel consumption and energy consumption, the measurement

### How can one select ball size in ball milling and how much

Popular Answers ( 1) Ball size depends on initial size of charge and ranges from 10mm 150mm dia. For particular material and initial size the ball size must be optimized. Please refer the link below and see if it works for you and other method is hit and trial.
