Jul 01, 2003· 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.

Experimental investigations concerning the residence time distributions of both the solid and the liquid phase have been carried out for a continuously operated stirred ball mill. It is admissible to consider the suspension as a single-phase fluid. Residence time distributions are found to be well described by an axial dispersion model.

Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.

the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill …

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.

Residence time is the time it takes a particle to complete the cycle. Space time is volume of the reactor over the velocity. If the volume does not change and the velocity remains constant then ...
