You could do that by measuring the material flowrate Q[tons/h] through the mill as well as the quantity M[tons] of material that accumulates within the mill. The retention time, also called residence time, is the ratio (M/Q) [h] .
Contact UsThe impact energy of the milling balls in the normal direction attains a value of up to 40 times higher than that due to gravitational acceleration. Hence, the planetary ball mill can be used for high speed milling. Schematic view of motion of the ball and powder mixture.
Contact UsThere are three types of grinding media that are commonly used in ball mills steel and other metal balls metal cylindrical bodies called cylpebs ceramic balls with regular or high density. Steel and other metal balls are the most frequently used grinding media
Contact Us2. The amount of steel ball in ball mill is reasonable. In general, the loading volume of the ball in the ball mill is lower than the horizontal line in the cylinder, and it is better to control the ball quantity at about 40 50
Contact UsMedia and Product Ball Mill Loading (Percentages are based on total volume of cylinder) NOTE With media load at 50%, voids are created equal to 20% of cylinder volume. These voids are filled when product is loaded into the mill. Mills can be loaded by volume or by weight based on products bulk density. DOWNLOAD PDF VERSION OF BALL MILL LOADING
