Mar 02, 2014· The residence time distribution (RTD) of mineral slurry and slurry holdup volume in an industrial ball mill has been successfully studies using tracer tests. Six different conditions of solids concentration and three levels of ball loading were assessed. The effects of the slurry solids concentration and the ball loading on the mean residence time of slurry were clearly depicted in the …

AbstractComparison between anticipated and measured mean residence time (MRT) along with analysis of the shape of residence time distribution (RTD) curves provides the most useful and valid information about mixing properties within a ball mill operating at industrial scale. In this work, the RTD measurements were carried out for a primary ball mill in closed circuit with hydrocyclones at two ...
Pulp samples collected around the ball mill or rod mill and hydrocyclones, screen or classifier (classification system) are screened and the cumulative weight percentage retained is calculated for several mesh sizes to obtain the Ball Mill Circulating Load. ... This is due to the lower residence time …
This is the instantaneous residence volume for pulp. 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.
Conventional practice is to have a mean pulp residence time of about an hour in each tank. Principle Of Fine Grinding In Ball Mill Mill For Sale. Industrial Ball Mills for Sale.

Determine Residence Time Of Material In A Ball Mill. Cutter mill is a size reduction equipment consisting of a series of uniformly spaced knives 2 to 12 in number attached to a horizontal rotor rotating knives which act against a series of stationary knives attached to the mill casing.The bottom of the mill has a screen attached to control the residence time of the particles inside the mill.
Residence time distributions normalized by mean residence time as a function of feed rate for centrifugal mill operated at G/D = 0.4, 60% ball filling, and mill revolution speed of 240 rpm. However, it was found that the shape of the RTD was changed somewhat with an increase in the mill revolution speed, as shown in Fig. 7 .
