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 rock is proportional to the
Duas leis empíricas a de Rittinger e a de Kick e uma lei semi teórica mais recente a de Bond o que temos para avaliara a energia real de fragmentação de sólidos As três equações podem ser obtidas para fins didáticos a partir da equação diferencial que relaciona o trabalho elementar necessário para fragmentar a unidade

100 1000 ENERGY DISTRIBUTION IN COMMINUTION A NEW APPROACH TO THE LAWS OF RITTINGER BOND AND KICK In other words there is no physical explanation why 1/n should be equal to as Bond suggests Experimental data show that 1/n can vary between [4 18] and the value chosen by Bond is a very good empirical approximation
The main assumption is that the energy required for breaking a particle is consumed by the new surfaces This is expressed by <mml math xmlns mml=

a La ley de Rittinger b La ley de Kick Problema Un material es molido tal que el tamaño medio de partícula es reducido desde 50 mm a 10 mm con un consumo de energía de 13 kW por cada kg/s alimentado Cuál será el consumo de energía necesario para moler el mismo material de un tamaño medio de 75
Existen variantes de esta Ley que se adaptan mejor a determinadas condiciones de trabajo la Ley de Rittinger enunciada en el año 1867 y que se basa en la hipótesis de las superficies de las partículas; la de Kick expresada en el año 1885 y que se basa en una hipótesis volumtrica y la teoría de Bond del año 1951 LEY DE RITTINGER
