here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit.,ball mill optimization,5 (12 ) t = 1.43 x 3.82 / 16.30.5 = 20.65 /4.03 = 5.1 min. the nearby cement plant operates with 20 mins retention time for clinker grinding in the ball mill &
Aug 11, 2010 Re: MATERIAL RETENTION TIME IN A BALL MILL & VRM. 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] . The flowrate Q could be measured from the production P [tons/h] and the
The retention time at batch ball milling was defined as the breakage characteristic time r of the feed. Mean residence time t was expressed by Eq. 3. The mean residence time in a mill is related to the breakage characteristics of feed materials,although no expression about it

The Critical Speed of the Ball Mill formula is defined as the minimum speed at which centrifuging occurs or the speed at which the centrifugal force is equal to the weight of the ball is calculated using Critical Speed of Ball Mill = (1/(2* pi))* sqrt (([g] /(Radius of the Ball Mill-Radius of the Ball))).To calculate Critical Speed of the Ball Mill, you need Radius of the Ball Mill (R
Jul 18, 2021 Now, Click on Ball Mill Sizing under Materials and Metallurgical Now, Click on Critical Speed of Mill under Ball Mill Sizing. The screenshot below displays the page or activity to enter your values, to get the answer for the critical speed of mill according to the respective parameters which is the Mill Diameter (D) and Diameter of Balls (d).. Now, enter the value
Third, in the typical ball mill, because coarse particles have a longer retention time, they have more “specific energy (kWh/t) applied to them” than do smaller particles, the study said. This means that “if a coarse particle is retained in the mill for a longer period of time, it is exposed to a larger amount of energy,” Bartholomew said
to ball filling variation in the mill. The results obtained from this work show, the ball filling percentage variation is between 1.2– 3.7% which is lower than mill ball filling percentage, according to the designed conditions (15%). In addition, acquired load samplings result for mill ball filling was 1.3%
The pilot mill is also equipped with a sensor measuring the ‘ball and pulp toe and shoulder angles’ (see Figure 3). These data are then used to calculate the total pulp and ball charge angle (see Graph 5). Graph 5 clearly illustrates how the ball charge stays quite compact till about 73% solids as the total media angle does not change

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill
