Material retention time in a ball MILL & VRM. Dear all can anybody suggest me how to calculate the material retention time in a closed circuit ball MILL in each compartment?The retention time, also called residence time, is the ratio (M/Q) [h] .
Cement Ball Mill Residence Time Vertical ore mill, vertical roller ore mill, retention time, and fineness of the finished ore can be achieved.
1 Over the past 15 years, mine-to-mill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.
a) Mill Geometry and Speed Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.
For an unchanged ball grading and the same true density of the feed material the number of stress events can be substituted by the average retention time of the feed inside the mill. The calculated values for the coarse and the fine material are plotted in Fig. 8
An Overview Of Lime Slaking And Factors That Affect The Process By: Mohamad Hassibi Chemco Systems, L.P. C. Ball Mill Slakers D. Batch Slakers A slaker must mix the correct amount of quick lime (CaO) and water, hydrate the retention time of 10 minutes at a full rated capacity. This means that from the

vertical mills retention time formula Cement Vertical Mill vs Ball Mill Mill The grinding process in ball mills and vertical roller corresponding to a longer retention time
Consumes 40% less power than comparable size horizontal ball mills Minimum retention time of 10 minutes at 100% feed rate Available sizes
Photographs of a glass ended laboratory ball mill show action of ball mass within the mill. The action of other grinding media is similar. In open circuit grinding the feed rate must be low enough to permit a longer retention time per particle within the mill. This assures that each particle of the incoming feed, however large, will be

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] .
Thus, it also has a greater influence on the mill retention time. The use of a finer ball charge results in a higher mill retention time and finer grinding giving a lower mill throughput (and separator circulating load). A fine ball charge cannot tolerate a high throughput without risking mill bypass.
