Rittinger's constant
WebNov 8, 2012 · The indices derived by Kick, Bond and Von Rittinger all assume a constant energy requirement per unit of size reduction regardless of the particle size range. Industrial and laboratory results indicate that the energy required for size reduction increases as the product particle size decreases.
