– Rittinger's law is applicable mainly to that part of the process where new surface is being created and holds most accurately for fine grinding where the increase in surface per unit mass of material is large. – Kick's law, more closely relates to the energy required to effect elastic deformation before fracture occurs, and is more ...

Current estimates of grinding power requirements used for equipment sizing are indirect indications often based on industrial experience or scaled up from laboratory tests. Work indices (Bond, Hardgrove, Kick, Von Rittinger, Hukki, et. al.) are also indirect and empirical equations that calculate the energy needed to

Oct 22, 2008Amine and glycol-based grinding aids (GA) were incorporated at various concentrations of 0.04, 0.06, and 0.08% of the cement weight. At Ec values lower than around 20 kWh/ton, test results have shown that cement fineness increases almost linearly with the increase in grinding energy according to Rittinger's law. Get Price.

Theory of Comminution. H. J. Kamack (E. I. du Pont de Nemours & Co., Inc., Wilmington, Del.)—Rittinger's law usually is stated to the following effect: "The work (or energy) consumed in particle size reduction is proportional to the new surface area produced.". The law has been stated substantially in this way by Taggart, Berry, Dalla ...

This study illustrated that Kicks law was applicable in the crushing range (above 1 cm in diameter) . Bond's theory was more suited to the particle size ranges involved in conventional ball and rod mill grinding (5 to 250 mm). Rittinger's law showed more _app1icability to the fine. the. V ...

Rittinger assumed that the energy required for size reduction is directly proportional to the change in surface area, and not to the change in length. He considered that for the grinding of solids, the energy required should be proportional to the new surface produced, assigning the value of 2 to the power n, and obtaining the Rittinger's law ...
