Most popular comminution laws are those proposed by Kick, Rittinger and Bond. Kick's Law (1885): Kick's law that can be applied to crushing states that "the work required for crushing a given quantity of material is constant for a given reduction ratio irrespective of its original size". Mathematically this law can be expressed as
It is the purpose of this paper to record and interpret a series of experiments made for the purpose of studying the consumption of energy in the crushing or fracturing of rock particles both coarse and fine. At the start, the expectation was to determine constants according to the Rittinger …

The double jaw crusher is designed for crushing hard materials, also quarried materials, sand and gravel, and recycling. [4, 5] crusher [4] The tie rod and compression spring ensure that the ...
To study the particle size distribution and energy variation law of hard coal under a load, an impact compression test of hard coal specimens under different impact loading conditions was carried out using a Φ50 mm diameter Separate Hopkinson Press Bar (SHPB) test system. We implemented the theory of dynamic impact energy of rock …
This paper presents the development of a new 3D finite element model for the simulation of UD composites materials under crushing, at the mesoscale.It is based on the Discrete Ply Model (DPM), enhanced with a new damage law to represent compression at constant stress due to localised crushing and its propagation from one element to …

Figure 5. Rittinger's Law The second theory of particle reduction is Kick's Law which is more accurate for coarse crushing where most of the energy is used to cause fractures to appear in existing cracks and deformities. This law applies best when the difference between the size of the coarse material and
crushing ratio, uneven particle size, and mainly used in a wide variety of applications, including construction and recycling demolition, quarrying and mining, etc.10 GYRATORY CRUSHER Gyratory crushers provide continuous crushing action and are used for both primary and secondary crushing of hard tough abrasive rock.

Kick's law is more suitable where coarser grinding takes place. This particular equation is valid for bigger particle size, for example, size reduction from 12 cm to 6 cm or from 6 cm to 3 cm. 6.6.3 Bond's Law. This law was developed by the Fred Chester Bond, an American mining engineer in 1952.

Fig. 2 is the SEM photo of the changes in the diamond powder size of the raw materials with different particle sizes before and after the super-high pressure (5.5 GPa) application without heating for a short time (30 s). It can be seen from the figure that the four raw diamond powders with different particle sizes were crushed to varying degrees …
This is an instance of what is commonly called a 'legal syllogism': a deductively valid argument that combines, as premises, (a) a general first-order statement of law (the 'major premise', as it is normally – if inaccurately – called), and (b) a statement about some aspect of the case in hand that instantiates the antecedent of that general …
Crushing a can by heating it, sealing it and cooling it rapidly is an excellent demonstration of the existance of atmospheric pressure. Many youtube videos describe the crushed can as an illustration of either Charles' Law or Gay-Lussac's Law. I don't agree. There are many variations on the theme, but the basic experiment involves heating a …
