For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R,, Charge% = 113(63H .

Ball charges: This calculator gives the surface and the average weight of the ball charges. It gives also a rough interpretation of the ball charge efficiency: Ball top size (bond formula): calculation of the top size grinding media (balls or cylpebs):Modifiion of the Ball Charge: This calculator analyses the granulometry of the material inside the mill and proposes a modifiion of ...

 · The motion of balls deep within the charge of a rotary grinding mill was investigated. Novel investigative techniques were used to track the motion of the balls, including Xray filming at 50 frames per second of both the front and side views of a transparent mill, and gammacamera filming of a radioactive ball. Analysis of the trajectories of the balls revealed several phenomena in the ...

Mill Steel Charge Volume Calculation We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill

 · We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The % loading or change volume can then be read off the graph below .

 · Re: how to estimate the wear rate for Ball mill. Most practical way to by measuring empty height and calculating the % volumetric filling of grinding way to make track of mill main drive kW consumption reduction and add makeup charge according to the extent of fall in power consumption.

Hardinge Ball Mill Charge Calculation. 2021 4 20 We can calculate the steel charge volume of a ball or rod mill and express it as the of the volume within the liners that is filled with grinding media While the mill is stopped the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill The loading or change.

 · Ball mill consist of a hollow cylindrical shell rotating about its axis. Axis of the shell horizontal or at small angle to the horizontal It is partially filled with balls made up of Steel,Stainless steel or rubber Inner surface of the shell is lined with abrasion resistant materials such as Manganese,Steel or rubber Length of the mill is approximately equal to its diameter .

calculated via manufacture`s ball charge program. At the time of this research, mill ball charged, feed rate, and average moisture were 7 tons (ball size was 100 mm) per week, 720 t/h and 5%, respectively. Then, ball abrasion rate was calculated by Equations 4, 5 and 6. Total mill feed per week = 720*24*7*= 114912 tons (4) Total ball charge per week = 7*106 g (5) Ball .
