Grinding time for ball mills Grinding & Classification

First you need the volumetric capacity of the mill, this is the volume of the mill at rest where the ore just reaches the discharge level (often about 1/3 of the internal volume). From this you need to subtract the volume of the grinding media. You now have the unit capacity. Then take the volumetric feed rate of the new ore per time.

Estimation of Grinding Time for Desired Particle Size

Jan 03, 2020· Grinding Studies. Two kinds of mills, BBM and LBM, were used to achieve the desired P 80 passing percentage of 150 μm with an acceptable range of hematite liberation (> 75%) at optimum grinding time. The BBM is a standard ball mill having a length and diameter of 300 mm × 300 mm with smooth liner as shown in Fig. 2.A rotating drum is attached to a gearbox and has adjustable speed knob.

Solids Choose the Right Grinding Mill Chemical Processing

Sep 13, 2010· Grinding time is related to media diameter and agitator speed via: T = KD 2 /N 1/2. where T is the grinding time to reach a certain median particle size, K is a constant that depends upon the material being processed, the type of media and the particular mill being used, D is the diameter of the media, and N is the shaft rpm. This equation shows that total grinding time is directly
