We provide all kinds of crushing machines including stationary crusher and mobile crusher
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 or
The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teach mill
R- the radius of the ball. The volume of a grinding ball is determined by the formula: V=4/3**R 3, where: V- the volume of the ball. PI constant, a mathematical constant that is equal to the ratio of the circles circumference to its diameter. 3.14 is a commonly used value for PI; R- the radius of the ball.

Mill Speed is commonly given either as the number (AO of revolutions per minute, or as is frequently treated as equal to (bulk volume of grinding media) -=- (mill volume). Vibratory ball mills agitate a charge by means of oscillating springs. Read More

The number of lifters generally can be determined by the rule-of-thumb: Number of Lifters = 3nD for double wave liners. = 6.6D for single wave liners where D is the mill diameter (m). Double wave liners are more suitable for ball sizes less than 60 mm. Otherwise, single wave is preferred.
Mill internal load volume (m3) = (19.55*297.96)/100 = 58.52 m3. (2) Ball volume in total mill load could compute by Equation 3. Mill Ball (%) = 100{[(ball volume in the 0.4 m3sample)* 58.52] / 0.4}/297.96 (3) According to the results (Table 1), the ball filling percentage was obtained 1.3%.
Ball Mill Finish Calculator. The Ball Mill Finish Calculator can be used when an end mill with a full radius (a ball mill) is used on a contoured surface. The tool radius on each side of the cut will leave stock referred to as a scallop. The finish of the part will be determined by the height of the scallop, amd the scallop will be determined by the stepover distance between cuts.
