Specific energy vs. Rittinger''s gr inding law parameter for the data from this study, and th ose extracted from Mani et al. (2 004), Bi tra et al. (2009), and Adapa et al. ( 2011). Figure 8.
Equation () is known as Rittinger''s Law. As the specific surface of a particle, the surface area per unit mass, is proportional to 1/L, eqn. () postulates that the energy required to reduce L for a mass of particles from 10 cm to 5 cm would be the same as that required to reduce, for example, the same mass of 5 mm particles down to ...
Neither of these two laws permits an accurate calculation of the energy requirements. 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.

In Summary, Kick''s law is better for larger particles and Rittinger''s for fine grinding, see Large particles are easier to break than smaller ones as they have more cracks and faults. Often the laws are used in conjunction with empirically given constants: it can be dangerous to use the book values without some test work.
Mar 25, 2015· Rittinger''s Law — The energy required for reduction in particle size of a solid is directly proportional to the increase in surface area. E = K R f c (1/L 2 – 1/L 1) Kick''s Law — The amount of energy required to crush a given quantity of material to a specified fraction of its original size is the same, regardless of the original size.

•A crushing law proposed by Rittinger in 1867 states that – the work required in crushing is proportional to the new surface created • This law, which is really no more than a hypothesis – is equivalent to the statement that the crushing efficiency is constant and, for a given machine and feed material – is independent of the sizes of feed and ...
