Rod Mill Grinding
· However, in rod mills the mean residence time for material transport decreases with increasing feed rate to the rod mill. These results are significant in the context of scaling up the feed rate to a tumbling mill. Increase in the media load was found to lead to an increase in material holdup, due to the increased resistance to material flow in both systems. The effect of media load on the ...

· Residence Time Distribution It is of general knowledge that particle size in milling is directly related to the residence time of that particle in the mill. What may not be well understood is how the residence time distribution of particles flowing through the mill effects the particle size distribution. The engineers of DRAISWERKE designed a horizontal mill experiment to study the effects of ...

Grinding time for ball mills
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.

Average residence time?
· The average residence time is a measure of the time it takes for the total stock or supply of the material to be cycled through a system. To compute the average residence time (T; assuming constant size of the system and constant rate of transfer), we take the total size of the stock (S) and divide it by the average rate of transfer (F) through the system: T=S/F. Example if a reservoir holds ...
