THE OPTIMAL BALL DIAMETER IN A MILL

Investigations were carried out in a laboratory ball mill having the size of DxL = 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40% by volume, the rotation rate was equal to 85% of the critical speed. Balls were made from steel: S4146, extra high quality, having hardness 62 ± 2 HRC according to Rockwell.

grinding media | Magotteaux

HighChrome media has a superior performance and creates steady milling conditions due to its low wear rate. For each specific alloy there is a constant hardness of all grinding media. This creates a positive influence in the downstream process. highChrome media is suitable for both wet and dry ore appliions in ball mills and tower mills.

Estimating Ball Consumption

For an improved understanding, the wear rate constant is directly related to the grinding media consumption rate expressed in grams of steel per kWh drawn by the mill, using the simple expression: where dr represents the diameter of the new makeup balls periodically charged to the mill.

 · This high energy ball mill agitates the charge of powder and balls in three mutually perpendicular directions at approximately 1200 rpm. It is highly energetic compared to the attrition and vibratory mills. A given reaction can typically take place an orderofmagnitude faster in the SPEX mill than in the typical attritor or vibratory mill.
