  • Crushing Energy & Work of Crushing Machines

    “The work of crushing is proportional to the reduction in diameter”—R H Richards: Ore Dressing, p 304 (1903) “The work required to crush rock is very nearly proportional to the reciprocals of the diameters crushed to”—A Del Mar: EngineeringIf the energy required to produce unit volume of new hole is obtained from the crater experiments it includes both elastic and fracture causing parts of the energy transferred to rock It has been shown, however, [2] that only a limited amount of energy can be transmitted through rock with a given pulseEnergy Required To Break Rock By Percussive Drilling |Rittinger’s theory and law of the energy expended in crushing of rock is that the work of crushing is proportional to the reduction in diameter; or, as I have more fully expressed it: “The work done in crushing is proportional to the surface exposed by the operation; or, better expressed for this purpose, the work done on a given mass of rockRock Crushing Theory and Formula using Kick &

  • Size Reduction and Energy Requirement ScienceDirect

    The estimation of energy for crushing by this method could be lengthy and tedious 343 JKMRCdrop weight crushing test Attempts at a much simpler and direct method of estimating the energy required for crushing rocks have been attempted by several workers such as Gross , Piret , Hoffler and Herbst The energy required to crush rock material is proportional to the amount of new surface area that is created Therefore, energy consumption increases with fines generation, and it can be estimated that 10 times more energy is spent in producing pond screenings thanAggregate production: Fines generation during rockbased on the ratio of the volume before to the volume after crushing Thus, the energy required is directly proportional to the size reduction, eg the same amount of energy is required to go from 2 to 1 cm as from 1 to 05 cm = i f K ln x x E k (114) Bond (1952) suggested that the total work required to break a cube of size x is11 Crushing and classification particlesuk
