Comparison of comminution circuit energy efficiency using

Simulation models were developed at the Julius kruttschnitt Mineral Research Centre to provide accurate estimates of power consumption for a wide range of equipment. With the models, a range of circuits and operating conditions can be compared by simulation for a particular ore type. Accurate models of classification allow for the interaction between classifier efficiency and target product

ChemTeam: Hess' Law - using bond enthalpies

a) Calculate the bond enthalpy of a C−H bond. (b) Calculate the bond enthalpy of a C−C bond. Solution: In the first equation, 4 C−H bonds are formed. −1652 kJ/mol divided by 4 = 413 kJ --- that's the bond enthalpy of a C−H bond Note that bond enthalpies are expressed as a positive value (energy put into the bond to break it), so I

Bond Work Index - an overview | ScienceDirect Topics

It involves grinding 50g of the material, e.g. coal, of specified size (16–30 mesh cut) in a specified ball-and-race mill for 60 revolutions. The amount of 200 mesh material is measured ( w grams) and the index is defined as I = 13 + 6.93 w. Thus, the higher the index, the easier is the grinding task.

Cement grinding optimisation - ScienceDirect

Based on the above considerations for crushing and grinding, the energy consumption for the clinker pre-crushing and ball milling can be estimated using the following Bond based model: (9) W = W c + W m As pre-crushing product size P c is equal to the mill feed size F 80 then: (10) W = A F 80 W i 10 P 80-10 F c + 1.3 ∗ 2.44 D 0.2 ∗ R r + (W i-7) F 80-F 0 F 0 R r ∗ P 80 + 10.3 1.145 ∗ P 80 ∗ W i 10 P 80-10
