Energy requirements in size reduction of solids * L G. Reddy INTRODUCTION It is no exageration to state that of the many approaches to understand different aspects of process of comminution, perhaps the most important one is the search for the sound rela-tionship between the size and the energy used. Basic laboratory investigations of comminution have been concerned mainly with 3 phases of the... GRINDING LAWS The three laws of Rittinger, Kick and Bond can all be derived from the follow- ing relationship, proposed by Charles (1957), between energy consumed and mate- rial size [5] : de - - k dn (1) y Setting the exponent n to 1, li or 2 upon integration defines the laws of Kick, Bond and Rittinger respectively. Of these laws. Bond's third law of comminution [1,2] has developed the

A commentary on the Kick, Bond and Rittinger laws of grinding. Confusion concerning the socalled general law of grinding proposed by Walker et al. is removed when it is realised that two forms of the law exist, quite different in physical meaning. The Kick and Rittinger laws are special cases of one form, and Bonds law is a special case of the other. grinding and crushing of sample . Mining... reduction was assumed to follow Rittinger’s Law. This gave a Rittinger’s constant of 28 J.m/kg for the given system. Using this value of Rittinger’s constant, the energy required to generate microfibres 1 µm in diameter was predicted as 2480 kJ for each 24 g charge in the PFI mill. It was deduced that microfibres generated in this way would cost a minimum of $2.37 per kilogram. Hence

- Application of Rittinger’s law and Kick’s Law Not an accurate calculation for 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. Kick’s law, more closely relates to the energy required to effect elastic
- CHE F313: Separation Processes II Kick’s Law • In 1885 Kick proposed another law, based on stress analysis of plastic deformation within the elastic limit • This law states that the work required for crushing a given mass of material is constant for same reduction ratio – that is the ratio of initial particle size to the final particle size – This law is more accurate than Rittinger

- • Kick’s law • Rittinger’s law • Bond’s law 11. Kick’s law 2 1 ln d d KE K KK = Kick’s constant, d1 (m) = the average initial size of pieces, d2 (m) = the average size of ground particles. d1/d2 = the size reduction ratio (RR) and is used to evaluate the relative performance of different types of equipment.
