note that the definition of particle size in bonds law is different: d80 = particle size such that 80% by weight of the sample is smaller than it. bonds law is often written in terms of the work index w i as

the size reduction theories of solid foods

rittinger’s law 5 states that the energy required for size reduction is proportional to the change in surface area of the particles. rittinger’s law gives better results with fi ne grinding where there is a much larger increase in surface area. according to rittinger 5 the d and d should be calculated as follows: 1 j j d g d = ∑ 6 1 i i d g d = ∑

rittinger

the surface area of a known weight of particles of uniform diameter is inversely proportional to the diameter hence von rittinger’s law equates to: 5.2 e v r = k 1 p − 1 f which is the solution of eq.

a commentary on the kick bond and rittinger laws of grinding

rittinger's law is logical if the specific energy is defined as that necessary to supply the surface energy of the fresh surface produced on fracture. however it is not used with this understanding because e is taken as the mill energy which is quite another matter- if e is mill energy eqn. 3 is an empirical law.

rittinger and kick's laws of crushing

rittinger and kick’s laws of crushing. using the notation of the original paper the number of these planes of fracture is represented by the expression 3 u/s 1 . the area of each plane of fracture is u². the total area of fracture is then equal to 3u² u/s 1 which may be written 3u² u-s /s.

unit operation size reduction

1. the mechanism of size reduction in the grinding process materials are reduced in size by fracturing them. in the process the material is stressed by the action of mechanical moving parts in the grinding machine and initially the stress is absorbed internally by the material as strain energy.
