bonds law equation in crushers
bonds equation crushing. bonds law equation in crusher nailsbykaty. · 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 ignored the minus sign on the 1652 value.
Bond Impact Crushing Work Index -Procedure
Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper.
