If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders.
Read OnForged steel balls are welcomed in different kinds of mines, like golden mines, copper mines etc. equipped with different size of ball mills.
Read OnFor example, if you had a boring mill that was operating at 100 kW and the apparent power consumed was 125 kVA, you would divide 100 by 125 and come up with a power factor of 0 .80 . Figure 3. kVA power Figure 4. Power triangle Note: A right power triangle is often used to illustrate the relationship between kW, kVAR and kVA . PF = = cosine θ
