worked examples involving bond039s equation in grinding millsEnergy Use of Fine Grinding in Mineral Processing. Dec 18,2013 · Fine grinding,to P80 sizes as low as 7 μm,is becoming increasingly important as mines treat ores with smaller liberation sizes.This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor.While fine grinding consumes less energy than primary grinding,it can still account for a substantial part of a mill's energy budget.

Bond Work Index (Energy equation) Grinding. BOND WORK INDEX.The Bond Work Index is a factor that measures the energy consumed in size reduction operation of the ore.The Bond's Work Index equation is: W=WI* (10 √P80 10 √F80) where.W= the energy input (Work input) per ton,kwh metric ton.WI= Work Index= specific energy per ton,kwh metric ton (characterizes the ore) Forging Wikipedia Forging is a manufacturing process involving the shaping of metal using localized compressive forces.The blows are delivered with a hammer (often a power hammer) or a die.Forging is often classified according to the temperature at which it is performed: cold forging (a type of cold working),warm forging,or hot forging (a type of hot working).For the latter two,the metal is heated,usually.
