calculation of ball mill residence time

Grinding time for ball mills - Grinding Classification ...

2021-10-16  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? - Answers

2011-9-12  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 ...

Ball Mill - an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
