Grinding time for ball mills Grinding & Classification Circuits Metallurgist & Mineral Processing Engineer. Hi all, I am wondering about the time of grinding in ball mills. How can I calculate the retention time? Which parameters should be considered?

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] . The flowrate Q could be measured from the production P [tons/h] and

How To Calculate Material Retention Time In Ball Mill I want to calculate the material present in kg in a ball mill if the fresh feed is 100 tph 300 tph is the mill outlet product it is a cement mill by this i shall be able to calculate the thickness of material layer inside the mill or in other words the filling of material alone in a ball mill excluding grinding media.

The advantage of this latter function is that the discharging from the mill of substantially unground portions of material is avoided. An object of the present invention is to provide a new and improved vibrating type ball mill for continuous wet grinding operations in which the retention time

The number of stresses can be characterised by the average retention time of the ground material inside the mill if the ball charge grading remains unchanged. The optimal retention time depends not only on the feed material and the desired comminution result but also

The optimal retention time depends not only on the feed material and the desired comminution result but also on the ball charge filling ratio and particularly on the L/D ratio.

OK mill and the retention time in the mill is shorter, the product will not be heated up as much as in a ball mill. This means that a lower degree of dehydration of the gypsum must be anticipated. This may not be a problem if the gypsum is sufficiently reactive to control the setting reactions, which is normally the case. If in special

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.

plant ball mill’s grinding efficiency (Fig. 1). The functional performance safety, in-tank interstage carbon retention, de-gritting, loaded carbon, carbon sizing, carbon grinding time is estimated for a desired energy input, E, in kWh/t. The mill speed is manually

Dec 10, 2004 The results obtained with the semi-industrial ball mill (see Fig. 4, Fig. 5) were analysed regarding the number of stress events (calculated according to Eq. ). 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.
