Grinding and cutting - Unit Operations in Food Processing - RL Earle. Perhaps the most extensive application of grinding in the food industry is in the milling where KK is called Kick's constant and fc is called the crushing strength of the per unit mass for the smaller particles, than that predicted by Kick's Law.

11.2 Crushing laws All the common basic equations relating energy requirement for comminution can be derived from a single ordinary differential equation kLm L E =− d d (11.2) where E is power, L is particle dimension (diameter), k is a constant and m takes one of three values depending on the particle size -2, -1.5 or -1.

Jan 01, 2013 Grinding is a unit operation widely used in the food industry and designed to reduce the size of materials to give a usable form or to separate their components. In developing countries, it is the common method for food powder processing. In general, grinding is part of a larger set of operations involved in the process of size reduction.

Crushing Theory • The amount of power required for crushing is a major consideration in selecting crushing equipment. • The greatest problems lies is the fact that most of the energy input to a crushing and grinding is absorbed by the machine itself, and only a small fraction of the total energy is available for breaking the material.

(3) Where, XF and XP are the lengths of feed and product respectively. Geankoplis (2004) reported that this law is valid in grinding of fine powders. Kick’s Law This law states that within the elastic limit, the work required for crushing is constant for the same reduction ratio irrespective of their original sizes and thus value of n = 1.

Mar 11, 2016 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 fully expressed it.

Jun 02, 2017 The equation for Rittinger’s Law can be written as E = K R f c (1 L 2 – 1 L 1) Where E=Energy, K R =Rittinger’s Constant, f c =crushing strength of the material, L 1 =initial length, and L 2 =reduced length. Kick’s Law states that the energy is proportional to the size reduction ratio. The equation for Kick’s Law can be written as.

Jun 02, 2017 The equation for Rittinger’s Law can be written as E = K R f c (1 L 2 – 1 L 1) Where E=Energy, K R =Rittinger’s Constant, f c =crushing strength of the material, L 1 =initial length, and L 2 =reduced length. Kick’s Law states that the energy is proportional to the size reduction ratio.
