Grinding time for ball mills - Grinding & Classification ...
Next compute the volumetric flow of slurry into your mill, as m³/h or L/s (match whatever volume units you used in the first step). Now divide the instantaneous volume by the vol flow (cancelling the vol units) and you are left with time units; this is your residence time.

Figure 8.15 Residence-time distribution function for solids in a continuously operating ball mill.into the mill and examining how the specific power input varies with mill size and with design and operating1.35 (8.114) To size a ball mill or rod mill that must process W tons/hr it is necessary to calculate...
Ball Mill Circulating Load - Mineral Processing & Metallurgy
This is due to the lower residence time per pass. In a properly designed circuit, each finely ground particle of the required product size has ample opportunity to exit the grinding circuit after each pass through the mill. As a result, few -10 micron fines are generated in the grinding circuit.
residence time in continuous ball mill
cement ball mill residence time cement ball mill residence time. According to the ball mill survey database presented in Section 4 the volumebased residence time of slurry in an overflow ball mill should be greater than 2 min for a less than m diameter ball mill and 1 min for a larger than m ball mill.
MATERIAL RETENTION TIME IN A BALL MILL & VRM - Page 1 of 1
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] .
Study of residence time distribution and mill hold-up for ...
Residence time distributions normalized by mean residence time as a function of mill revolution speed for centrifugal mill operated at G/D = 0.4, 60% ball filling, and feed rate of 150 g/min. It is convenient to represent the RTD in a functional form.

how to calculate residence time in a ball mill
Calculating Power Draw when sizing Ball Mills. But the slurry charge in an overflow ball mill doesnt change very much because most of the slurry occupies the void space in between the balls, so as the circulating load increases, the discharge rate also increas This means the residence time goes down but the power doesnt really change that much On the other hand, for SAG mills with ....
Study of residence time distribution and mill hold-up for ...
It is important to determine the residence time distribution (RTD) of a mill in order to predict the performance of the mill. In this study, the residence time distribution of a continuous centrifugal mill was measured experimentally by using aluminum powder as a tracer in a dry-grinding environment.
